The method comprises: (a) the primitive processing unit selects at least one primitive that needs to generate a picture from the database; (b) reads a word template of the word application software, and sets the word template to be displayed. a parameter of the picture, the parameter including a view of the picture displayed in the word template; (c) the picture processing unit generates a picture of a picture, the view angle of the picture and the set image displayed on the word template (d) pasting the generated picture onto the read word template; (e) repeating steps (b) through (d) above until the selected element has generated a picture; and (f ) Display the generated image on the word application software.

Compared with the prior art, the method for generating a picture element can automatically generate a plurality of picture pictures of different perspectives at a time according to user requirements, thereby saving working time and improving work efficiency.

As shown in FIG. 1, it is a hardware architecture diagram of a preferred embodiment of the method for generating a picture element of the present invention. The hardware architecture diagram includes a host 1 on which the word application software 101 is run. The generated multiple views of the image are displayed on the word template of the word application software 101. In the preferred embodiment, the word template is used. The type is the report type. Each word template is used to display a final generated picture, and each word template is provided with view information displayed on the picture, and the view information includes: a left view, a right view, a positive view, and the like. The host computer 1 further includes a drawing software 102, which may be a Computer Assistant Design (CAD) software, a Pro/Engineer software, or the like. The drawing software 102 is also connected to the database 2, and the database 2 can be built in the host 1 or externally placed in the host 1. The database 2 stores the primitives drawn by the drawing software 102. The meta refers to the graphic data, which corresponds to the entities visible on the drawing interface. The drawing software 102 includes a primitive processing unit 103, and the primitive processing unit 103 is configured to process the primitives in the database 2 that need to generate a picture. It should be noted that when the primitive processing unit 103 is embedded in different drawing software 102, different interfaces, such as an application programming interface (API), need to be set to be compatible with the drawing software 102. The host 1 is also connected to the input device 3 and the output device 4. The input device can be a keyboard, a mouse, or the like. The output device 4 can be a display, a printer, or the like.

As shown in FIG. 2, it is a flowchart of a preferred embodiment of the method for generating a picture element picture of the present invention.

In step S20, the primitive processing unit 103 selects at least one primitive that needs to generate a picture from the database 2 according to the user request.

In step S21, the word template function of the word application software 101 is opened.

Step S22, reading a word template and setting a parameter of a picture of the primitive to be displayed by the word template, the parameter including a view angle of the picture of the primitive displayed in the word template.

In step S23, the primitive processing unit 103 generates a picture of a picture element, and the view angle of the picture is consistent with the picture view angle set in the word template parameter.

In step S24, the generated picture is pasted to the read word template by using a clipboard.

In step S25, the picture on the clipboard is cleared.

In step S26, it is determined whether there are still primitives in the selected primitive that do not generate a picture. If yes, go to step S22. If not, the process proceeds to step S27.

In step S27, the word template function is closed, and the generated picture is displayed on the word application software 101.

As shown in FIG. 3, it is a refinement flowchart of step S23 in FIG. 2.

In step S30, the primitive processing unit 103 receives the parameter of the picture that needs to be generated input by the user. The parameters include: length and width of the picture, resolution, storage size, and so on.

In step S31, it is determined whether the received parameter is legal. In the preferred embodiment, determining whether the parameter is legal is to determine whether the length and width of the received picture is greater than zero. If the length and width of the received picture are greater than zero, it indicates that the received parameter is legal; If the picture length and width values are not greater than zero, the received parameters are invalid. If the result of the judgment is that the received parameter is legal, the process proceeds to step S32. If the result of the judgment is that the received parameter is invalid, the process proceeds to step S38.

In step S32, it is determined whether the storage size of the picture is within the picture storage size range of the word template. In the preferred embodiment, the picture storage size range of the word template is [0.3M, 3.0M]. When the storage size of the picture is not within the picture storage size range of the word template, the process proceeds to step S33. When the storage size of the picture is within the picture storage size range of the word template, the process directly proceeds to step S34.

In step S33, the storage size of the input picture is adjusted in proportion, and the process proceeds to step S34. The storage size of the adjusted input image refers to that the user re-enters the storage size of the image to be generated, and adjusting the storage size of the image is implemented by adjusting the length and width values of the image. For example, if the storage size of the image is 30M, the image needs to be reduced by at least 10 times, that is, the aspect ratio of the image is , the length and width of the picture are followed Shrink to the range of [0.3M, 3.0M] respectively.

Step S34, setting the angle of view of the picture according to the view parameter of the word template displayed in the step S22 in FIG.

Step S35: Generate a device independent bitmap (DIB) format picture of the primitive according to the set angle of view and the size of the picture. Since the picture of the DIB format cannot be displayed on the word template of the word application software 101, the process proceeds to step S36.

In step S36, the generated picture in the DIB format is converted into a picture in the Device Dependent Bitmap (DDB) format, and only the picture in the DDB format can be displayed on the word template of the word application software 101.

Step S37, the picture of the converted DDB format is pasted on the clipboard, and the bitmap and the bitmap control code of the picture in the DDB format on the clipboard are output, and the process ends. In step S24 of FIG. 2, the generated picture is pasted to the read word template by using a clipboard, and is searched by using the bitmap and the bitmap control code of the clipboard outputted in step S23. DDB formatted image, then paste the found image into the word template.

In step S38, the parameter input by the user is prompted to be illegal, and the process ends.

As shown in FIG. 4, it is a refinement flowchart of step S36 in FIG.

In step S40, the picture information of the generated picture in the DIB format is read. The image information includes: image size, resolution, pixel information, color palette and other information.

Step S41, creating a picture of the DDB format of the same size as the picture of the DIB format.

Step S42, setting pixel element information of the created DDB format picture according to the read pixel bit information. The generated DDB format picture has a color organization compatible with the output device 4.

Step S43, deleting the picture in the DIB format.

Step S44, outputting a picture in the DDB format.
