In one example, an image forming apparatus or a corresponding computer device first determines user information of document data to be formed, and then acquires a background point code image matching the user information from a point code file.

In some embodiments, the user information may include: document name, document signature, document author, device information indicating a terminal device that prints the document data to be formed, or user name bound to the terminal device. For example, when the document name of the document data to be formed contains "three by three", the background point code image matching "three by three" may be determined as the target background point code image. Alternatively, when it is instructed that the terminal device to print document data to be formed includes "computer of lie four", the background dot code image matching with "lie four" may be determined as the target background dot code image. Based on the mode, different background point codes can be set for the document data to be formed of different users according to the personalized requirements of the users.

S30, generating preset encoded image data based on the document data to be formed and the preset background point code image;

in some embodiments, after acquiring the document data to be formed and the preset background point code image, the preset background point code image may be set to a background layer of the document data to be formed to generate the preset encoded image data.

In some embodiments, the preset background point code image may include a raster image or a vector image. When the preset encoded image data is generated, it may be determined whether the preset background point code image is a raster image. When the preset background point code image is a raster image, preset encoded image data can be generated based on pixel information corresponding to document data to be formed and pixel information corresponding to the preset background point code image.

Specifically, when the preset background dot code image is a raster image, one implementation may use the preset background dot code image as a background layer, so as to perform pixel operation with the document data to be formed, so as to prevent the document data to be formed from covering the background dot code image.

Optionally, the image forming apparatus may perform pixel operation on the preset background point code image and the document data to be formed through a rendering function (bitblt), so as to realize transparentization of the preset background point code image or the document data to be formed, and enable the document data to be formed and the background point code image not to be covered by each other. Note that when the image accuracy requirement is high when adding the background point code to document data to be formed, it is preferable not to perform processing such as stretching on the background point code.

In some embodiments, when the background dot code image is preset as a raster image, the bit depth bit number corresponding to the raster image may also be obtained. And judging whether the bit depth bit number corresponding to the raster image is greater than 1, and if the bit number is greater than 1, performing binarization processing on the preset background point code image. And then, generating preset encoded image data according to the preset background point code image subjected to binarization processing and the document data to be formed, and reducing the data volume of the preset encoded image data so as to reduce the size of the generated encoded file.

In some embodiments, when generating the preset encoded image data, it may be determined whether the preset background point code image is a lost image. If the preset background point code image is a loss image, preset encoded image data may be generated based on the document data to be formed and the loss information corresponding to the preset background point code image. Optionally, when the preset background point code image is a vector image, the vector coordinates of each background point code in the vector image may be acquired. The background dot code may then be formed in the document data to be formed according to the vector coordinates of the background dot code. Specifically, the background point code may be drawn on the surface of the document data to be formed by using a StrokePath tool and a brush tool according to the vector coordinates of the background point code.

S40, data output operation is performed based on the preset encoded image data, and an encoded file is generated.

After the preset encoded image data is acquired, the image forming device or the computer device directly generates an encoded file based on the preset encoded image data, the encoded file may directly display a display unit of the image forming device or the computer device, or the encoded file may directly be stored in a memory of the image forming device or the computer device, or the encoded file may also be subsequently directly exported from the image forming device or the computer device in a file manner.

According to the code file generation method provided by the embodiment of the application, the document data to be formed and the preset background point code image are obtained, the preset code image data are generated based on the document data to be formed and the preset background point code image, the data output operation is performed based on the preset code image data, and the code file is generated.

Before generating the encoded file, the embodiment of the present application further includes performing color processing on the document data to be formed and the preset background point code image by using a color conversion unit provided in a driving unit installed in the image forming apparatus or the computer device, so that color information of a portion corresponding to the document data to be formed in an output medium obtained by printing the encoded file by using the image forming apparatus is different from a color of a portion corresponding to the preset background point code image, specifically, when the color conversion unit receives the document data to be formed, the color conversion unit sets preset first information indicating that the processing of the document data to be formed is currently performed, and changes a color conversion target color into the first color; when the color conversion unit receives the preset background point code image, the preset mark information is set as preset second information, which indicates that the preset background point code image is currently processed, and the color conversion target color is changed into a second color; and respectively processing the document data to be formed and the preset background point code image according to the determined color conversion target color.

Specifically, when the driver is of an RGB color space type such as PCL, the driver converts the received document data to be formed and the preset background dot code image into CMYK color space data, so that the colors corresponding to the document data and the preset background dot code image in an output medium obtained by converting the CMYK color space data by image forming printing are different.

When the driver is of a CMYK color space type such as PS, the driver performs color conversion on the received document data to be formed and the preset background dot code image, so that the output medium obtained by printing the converted data by the image forming device has different corresponding colors.

Specifically, taking the first color as cyan as an example, when the driver is of an RGB color space type such as PCL, the RGB value of one pixel in the document data to be formed received by the driver is (100, 150, 200), the RGB value of the converted pixel is (255, 255, 140), and then the CMYK value obtained by spatially converting the RGB value obtained by conversion into CMYK is (45, 0, 0, 0), so that the portion of the output piece corresponding to the document data to be formed, which is obtained by the image forming apparatus performing the output operation, is cyan.

Specifically, taking the second color as black as an example, when the driver is of an RGB color space type such as PCL, the RGB value of one pixel in the preset background dot code image received by the driver is (255, 255, 255), and the CMYK value obtained by spatial conversion of CMYK obtained by the conversion is (0, 0, 0, 100), so that the output piece and the corresponding part of the preset background dot code image obtained by the image forming apparatus performing the output operation are black.

Therefore, the coded file generated by the image forming device or the computer equipment is printed and output subsequently, a medium which can be written and identified by the intelligent pen is obtained, and convenience is brought to users.

And S34, the preset background point code image is a raster image, and preset coding image data is generated based on the pixel information corresponding to the document data to be formed and the pixel information corresponding to the preset background point code image.

And S35, the preset background point code image is a vector image, and preset coding image data is generated based on the document data to be formed and the vector information corresponding to the preset background point code image.

The manner of generating the preset encoded image data in S34 and S35 is the same as that described above, and is not limited herein.

S36, data output operation is performed based on the user information and the preset encoded image data.

Specifically, the corresponding data operation is executed according to the user information. For example, the number of users may be determined based on the user information, and the number of output operations may be determined based on the number of users. In the embodiment of the application, the output operation can be performed on the preset encoded image data corresponding to different users, and the output operation is output to the folders corresponding to the user names.

The method for generating the coding file in the embodiment of the application can be applied to the image forming operation process performed by connecting the host computer and the image forming equipment. Image forming apparatuses include, but are not limited to, printers, copiers, facsimile machines, scanners, or all-in-one machines that integrate printing, copying, faxing, scanning, etc. functions to print images or characters on an image forming medium.

Specifically, the image forming job described above in the embodiment of the present application may be exemplified by, but not limited to, a print job. The host computer is provided with a driving program for image formation, and a main control process is operated in the host computer and is used for monitoring the whole printing operation. In an application scenario of the present application, the image forming apparatus is configured to print a content document with background dot codes, where the content of the document may include characters, images, and tables, or may not include any content and is a blank document.

In the image forming apparatus in the embodiment of the application, during a job process, a master process controls the entire printing process of the apparatus, for example, obtains content of a printed document, and sends the printed content to a print driver, and the print driver is responsible for converting the printed content into print data and sending the print data to a print engine, so as to print out a medium with a background dot code. In other embodiments of the present application, the host process may also be executed in other computer devices than the image forming device, such as a PC or the like that performs network communication with a printer.

As shown in fig. 4, the master process is running, and in step 21, dot code mode printing is first selected by the user. In the embodiment of the application, the user can select the dot code printing mode in a click or double-click mode or the like on the user interface, so that the printed medium contains the specially encoded background dot code. The user can also select a non-point code printing mode, and the printed medium only contains document contents and does not have background point codes, so that redundant description is omitted.

The print driver obtains the print instruction of the dot code mode sent by the main control process, and executes step 22, i.e. creating a print canvas.

In step 23, the document to be printed is acquired by the host process according to the operation of the user. And step 24, acquiring the background point code corresponding to the printed document by the main control process according to the specified operation of the user. Alternatively, steps 23 and 24 may be performed before step 21.

Specifically, the printed document may be a PDF, WORD, or other type of file, and may include, but is not limited to, contents such as images, text, tables, and the like, and at least includes one page of contents.

According to the preset setting, the document to be printed corresponds to different background point code images, furthermore, the contents of different pages of the document can also correspond to different background point code images, and the different background point code images can be set to different names and stored in different paths, for example, stored in a folder corresponding to the document name.

Therefore, the main control process can acquire the original document content to be printed and the corresponding background point code image according to the operation of the user and send the original document content and the corresponding background point code image to the printing driver.

After the original document content and the background dot code image are obtained, the print driver may fuse the image to the print canvas to generate a preset encoded image, as in step 25 of fig. 4. The preset encoded image may generate an encoded file to be transmitted to the print engine as print data.

The driver further sends the print data to the print engine for the print engine to execute the print job.

In some embodiments of the present application, in a process of fusing an original document content and a background dot code image to a printing canvas, if the original document content includes an image and the background dot code image is also an image, when the original document content and the background dot code image are directly copied to the printing canvas in a color image manner, a processing amount of data is increased, so that a generation speed of print data is reduced, and a printing speed is also reduced, and in an actual measurement process, an image forming apparatus with a general printing speed of 33ppm is reduced to 10 ppm. Therefore, further optimization of the present application is necessary.

In the preferred embodiment of the present application, the background dot code image is set to a black-and-white image, so that printing with a code in the image forming apparatus is only required to be performed in black (K). And the document content preferably does not contain black, so that the infrared identification device of the intelligent pen can identify the background point code at different induction frequencies on a printed medium without being interfered by the document content. Therefore, the background point code image is set as a black-and-white image, so that a compressed space can be provided, and the data processing amount is reduced. In the generation process of the printing data, only image elements in document elements need to be distinguished from the background point code image, binarization processing is carried out on the background point code image so as to reduce the size of the background point code image, and the processed background point code image is fused into a printing canvas.

In embodiments of the present application, the background point code image may be distinguished from the image elements in the document in a variety of ways. For example, the host process copies the background dot code image through a preset program and copies it into the print canvas. And the master control process analyzes elements (including images, characters and the like) in the document content through other programs except the preset program, and copies the elements into the printing canvas in a regional mode through the programs except the preset program. When the point code image is copied, the preset program sends a message to the print driver, so that the print driver can distinguish the background point code image from the content image of the original document.

As shown in FIG. 5, in one embodiment, the host process copies the background point code image through a pre-set UI program for a print Driver (Driver) to distinguish the background point code image from other images. The drvsecape function and the DrvBitBlt function run in parallel in the print Driver.

Specifically, in fig. 5, the UI program starts executing step 31 to start running. At which point the UI program sends a message to Driver.

In step 32, the drvsecape function is in the message listening process, and when a message executed by the UI program is received, step 33 is executed.

The DrvEscape function sets the global flag, step 33, indicating that the background point code image is being copied into the print canvas at this time.

At step 34, the UI program calls the StretchDIBits function to draw the print canvas.

And step 35, monitoring the running of the StretchDIBits function by the DrvBitBlt function, and starting working.

In step 36, the DrvBitBlt function first determines whether the global flag is set. If yes, go to step 37, otherwise go to step 38.

At step 37, the DrvBitBlt function performs image compression and copies to the print canvas.

The DrvBitBlt function copies the image directly into the print canvas, step 38.

In step 39, the operation of the DrvBitBlt function is finished, and the StretchDIBits function is also stopped.

In step 310, the UI program sends a message to Driver to stop running, and the drvsecape program resets the global flag.

Therefore, in the embodiment, the background point code image is copied through the preset UI program for distinguishing by the print driver, and binarization processing is performed on the background point code, so that the data processing amount is reduced, and the print driver does not perform additional processing on images other than the background point code image, so that the accuracy of the original document content is ensured.

In the embodiment of the present application, the print driver performs binarization processing on the background dot code image.

In an embodiment of the present application, the binarizing processing on the background point code image may include: and compressing the image bit depth of the background point code image.

As shown in fig. 6, in an embodiment of the present application, a processing flow for performing binarization processing on a background point code image is provided, and includes:

and step 41, acquiring SURFOBJ parameters of the image objects of the background point code images.

Specifically, the main control process sends the image object SURFOBJ parameter of the background dot code image to the print driver. The print driver acquires the parameters, and retains the original SURFOBJ parameters.

Step 42, determining the image bit depth of the background point code image.

Specifically, in one embodiment, the image bit depth may be a variety of bit depths in the RGB color space, which in this example may be illustrated as 24 bits, i.e., R, G, B with 8 bits of binary numbers in each color channel.

And 43, converting the color image corresponding to the background point code image into a gray image when the bit number of the image bit depth of the background point code image is greater than 1.

Specifically, taking a 24-bit color image as an example, the 24-bit color image can be converted into an 8-bit grayscale image.

Step 44, converting the gray scale image into a binary image.

Specifically, the 8-bit grayscale image is converted into a 1-bit binary image, which can be performed by, but not limited to, using a Halftone algorithm.

The original SURFOBJ parameters of the image are restored, step 45.

Specifically, when the image is binarized, the SURFOBJ parameter of the image object will change, and in the embodiment of the present application, after the print driver binarizes the background point code image, the original SURFOBJ parameter of the image object is restored and returned to the master control process, so that the efficiency of the master control process for continuing further execution is ensured.

The printing driver obtains the image surface parameters of the background point code image sent by the master control process, which correspond to the printing canvas, and keeps the image surface parameters unchanged after the binaryzation processing is carried out on the background point code image, thereby ensuring that the master control process avoids the occurrence of program errors in the process of monitoring the printing operation and ensuring the program operation efficiency.

As shown in fig. 7, an embodiment of the present application provides an encoding file generating apparatus.

Specifically, the encoding file generating apparatus 500 includes:

an output unit 504, configured to perform a data output operation based on the preset encoded image data, and generate an encoded file.

The above-described code file generation apparatus is explained below in some embodiments of the present application.

A document acquiring unit 501 for acquiring document data to be formed.

In the embodiment of the present application, the manner of obtaining the document data to be formed is not limited, and the document data to be formed sent by other devices connected to the image forming device may be received by the image forming device, where the other devices include the computer device installed with the driver, and are not limited herein; or the image forming apparatus directly accesses to-be-formed document data stored therein to acquire the to-be-formed document data, specifically, the to-be-formed document data is stored in a storage unit built in the image forming apparatus, and the image forming apparatus directly accesses to acquire the document data stored in the image forming apparatus based on the received instruction.

A background point code image obtaining unit 502, configured to obtain a preset background point code image.

Specifically, the preset background point code image comprises point codes arranged according to a certain rule, and when the intelligent pen point slides over the point codes, the intelligent pen obtains the arrangement information of the point codes which are slid by the pen point, so that the position information combination corresponding to the pen point is determined, and the writing track of the pen point is determined.

In some embodiments, the manner of obtaining the preset background point code image may include: and directly generating a preset background point code image based on a preset rule. That is, when the image forming apparatus or the corresponding computer device determines that the document data to be formed needs to be provided with the background point code, the image forming apparatus or the corresponding computer device directly generates the preset background point code image according to the preset rule.

Alternatively, the image forming apparatus or the corresponding computer device may set a point code folder for storing a preset background point code image from an external device. Alternatively, the image forming apparatus or the corresponding computer device may obtain the point code file from a usb disk or a hard disk. Alternatively, the image forming apparatus or the corresponding computer device may acquire the point code file from a terminal device having a connection relationship. Wherein the terminal device having a connection relationship with the image forming apparatus or the corresponding computer device may include: a terminal device that establishes physical connection with the image forming apparatus or a corresponding computer device; or, a terminal device that establishes wireless connection with the image forming apparatus or a corresponding computer device; alternatively, a terminal device connected to the same local area network as the image forming apparatus or the corresponding computer device.

Alternatively, when the background dot code needs to be set for document data to be formed, the image forming apparatus or the corresponding computer device may acquire a preset background dot code image from the dot code folder. Of course, when the image forming apparatus or the corresponding computer device acquires the preset background dot code image in the dot code folder, the association relationship between the printing parameters of the document data to be formed and the arrangement and/or size rules of the background dot codes and/or the association rules between the user information of the document data to be formed and the background dot codes may be further combined to acquire the preset background dot code image matching the document data to be formed from the dot code folder. In one example, an image forming apparatus or a corresponding computer device first determines user information of document data to be formed, and then acquires a background point code image matching the user information from a point code file.

In some embodiments, the user information may include: document name, document signature, document author, device information indicating a terminal device that prints the document data to be formed, or user name bound to the terminal device. For example, when the document name of the document data to be formed contains "three by three", the background point code image matching "three by three" may be determined as the target background point code image. Alternatively, when it is instructed that the terminal device to print document data to be formed includes "computer of lie four", the background dot code image matching with "lie four" may be determined as the target background dot code image. Based on the mode, different background point codes can be set for the document data to be formed of different users according to the personalized requirements of the users. In some embodiments, before acquiring the document data to be formed and the preset background point code image, an embodiment of the present invention further includes: acquiring preset mode information, and determining that a background point code needs to be set for corresponding document data to be formed according to the preset mode information. Optionally, the obtaining of the preset mode information may include obtaining a preset mode setting instruction, or determining that a preset background point code image exists. And when a preset mode setting instruction is acquired or a preset background point code image is determined to exist, determining that a background point code needs to be set for the corresponding document data to be formed.

In some embodiments, obtaining the preset mode setting instruction may include: and acquiring the preset mode setting instruction according to the setting operation of the user on the image forming device. For example, when a user issues a print job of document data to be formed through a terminal device, a prompt message of "whether to set a background dot code" may be displayed on the image forming device, and the preset mode setting instruction is acquired through a confirmation operation of the user on the relevant prompt. Alternatively, the image forming apparatus may integrate operation options, and the user may select the operation options according to the image forming apparatus. When the image forming apparatus sets: when the operation option of the background point code is set for the printing document, the image forming apparatus sets the background point code for all the received document data to be formed.

In some embodiments, the image forming apparatus may further acquire a preset mode setting instruction according to a terminal apparatus that provides document data to be formed. Specifically, when the user issues a print instruction of document data to be formed through the terminal device, the print instruction may include the preset mode setting instruction. Optionally, after the user issues the print instruction of the document data to be formed through the terminal device, before the document data to be formed is printed, the user may also issue the preset mode setting instruction through the terminal device.

An image generating unit 503 for generating preset encoded image data based on the document data to be formed and the preset background point code image.

Specifically, in some embodiments, after acquiring the document data to be formed and the preset background point code image, the preset background point code image may be set in a background layer of the document data to be formed to generate the preset encoded image data.

In some embodiments, the preset background point code image may include a raster image or a vector image. When the preset encoded image data is generated, it may be determined whether the preset background point code image is a raster image. When the preset background point code image is a raster image, the preset encoded image data can be generated based on the pixel information corresponding to the document data to be formed and the pixel information corresponding to the preset background point code image.

Optionally, the image forming apparatus may perform pixel operation on the preset background point code image and the document data to be formed through a rendering function (bitblt), so as to realize transparentization of the preset background point code image or the document data to be formed, and enable the document data to be formed and the background point code image not to be covered by each other. Note that when the image accuracy requirement when adding the background point code to the document data to be formed is high, it is preferable not to perform processing such as stretching on the background point code.

An output unit 504 for performing a data output operation based on preset encoded image data to generate an encoded file.

The output unit 504 is specifically configured to perform color conversion processing on the document data to be formed, so as to set a color conversion target value corresponding to the document data to be formed as a first color; performing color conversion processing on the preset background point code image so as to set a color conversion target value corresponding to the document data to be formed to a second color; and when the color conversion target value corresponding to the document data to be formed is set to be a first color and the color conversion target value corresponding to the document data to be formed is set to be a second color, printing an output medium obtained by the coded file, wherein the output medium comprises a first part corresponding to the document data to be formed and a second part corresponding to a preset background point code image, the color information of the first part is the first color, and the color information of the second part is the second color, and the first color is different from the second color.
