The DWF files corresponding to the drawings can be read by the compiled DWF Toolkit, so that the DWF files corresponding to the drawings are obtained.
In operation S220, an image file corresponding to the image is acquired, and a new DWF file is generated according to the image file and the geometry information file, wherein the new DWF file corresponds to the drawing in which the image is inserted.
In the embodiment of the present disclosure, the image file corresponding to the image may be a file in a picture format, for example, a picture file in JPEG, PNG, or the like. The embodiment of the disclosure can read the content in the image file corresponding to the image.
According to an embodiment of the present disclosure, wherein generating the new DWF file from the image file and the geometry information file may include: creating a new geometric information file, reading the contents of the geometric information file and writing the contents of the geometric information file into the new geometric information file in sequence, and writing the contents of the image file into the new geometric information file.
For example, an embodiment of the present disclosure may create one or more new geometric information files, then read the contents of the geometric information files in the DWF file corresponding to the drawing through the DWF Toolkit, and sequentially write the read contents into the created new geometric information files, where at this time, the new geometric information files include geometric information corresponding to the drawing. Then, the contents of the acquired image file are written into a new geometric information file, and at this time, the new geometric information file contains both the geometric information corresponding to the drawing and the content information of the inserted image.

Fig. 3 schematically shows a flow chart of a DWF file mapping method according to another embodiment of the invention.
As shown in fig. 3, the method includes operations S210 to S220 and S310 to S340. Operations S210 to S220 are the same as or similar to the method described above with reference to fig. 2, and are not described again here.
In operation S310, position information of the image insertion drawing is determined.
According to the embodiment of the disclosure, the user can determine the position information according to the position in the drawing where the image is to be inserted. For example, if the image needs to be inserted into the center of the drawing, the determined position information may be the center of the drawing. For example, if the image needs to be interpolated 4 feet from the left boundary of the drawing and 5 feet from the lower boundary, the determined location information may be (4 feet, 5 feet), etc.
In operation S320, the location information is written in the new geometry information file.
According to an embodiment of the present disclosure, writing the location information into the new geometry information file may include: converting the position information into coordinate position information, and writing the coordinate position information into a new geometric information file.
Wherein converting the location information into coordinate location information may include: the method comprises the steps of obtaining dimension information and coordinate information of a drawing from a DWF file, determining the corresponding relation between the dimension information and the coordinate information, and converting position information into coordinate position information according to the corresponding relation.
In the disclosed embodiment, the actual dimensions of the drawing, for example, the actual length and width, etc., can be obtained from the DWF file. Coordinate information of a specific point of the drawing may also be acquired from the DWF file, for example, a coordinate position of a lower left corner point of the drawing in the internal coordinate system and a coordinate position of an upper right corner point of the drawing in the internal coordinate system may be acquired. The corresponding relation can be established according to the real size of the drawing and the corresponding coordinate information. Thus, after the position information into which the image is to be inserted is determined, the coordinate position information in the internal coordinate system into which the image is to be inserted is determined based on the correspondence relationship. The coordinate position information is written into the new geometry information file so that the position of the image insertion can be specified.
In operation S330, configuration information of the image is written in the new geometric information file, wherein the configuration information includes size information of the image.
According to the embodiment of the present disclosure, configuration information about configuring an image may also be written into a new geometric information file, for example, size information or resolution information of the image or the like may be written into the new geometric information file to implement the configuration of the image.
In operation S340, it is checked whether the information on the original drawing part in the new geometry information file is identical to the information in the geometry information file.
In the embodiment of the present disclosure, an end character of the information on the original drawing part in the new geometry information file may be used as a delimiter for separating the geometry information in the new geometry information file from the content information of the written image file. For example, after the content in the geometry information file in the read DWF file is written into the new geometry information file, the end character of the content of the geometry information file is used as a delimiter, and then the content information of the image is written into the new geometry information file after the delimiter.
According to an embodiment of the present disclosure, verifying whether the information about the original drawing part in the new geometric information file is consistent with the information in the geometric information file may include: and checking whether the information before the delimiter in the new geometric information file is consistent with the information in the geometric information file.
For example, in order to ensure that the content of the original drawing before the drawing is pasted does not change with the drawing behavior, the new DWF file may be checked, and since only the new geometric information file in the new DWF file is changed, only the new geometric information file may be checked, for example, only the information about the original drawing part in the new geometric information file may be checked.
The embodiment of the disclosure can specify the position and the size of the image to be pasted, the pasted image and the original paper are integrated, and the relative position of the image and the drawing is not influenced even if operations such as rotation and translation are performed on the drawing in the file.
