Description
Technical Field
The invention mainly relates to the technical field of computer aided design, in particular to a method for embedding a CAD font file into a DWG document and automatically installing the CAD font file.
Background
Cad (computer Aided design) is an important application field of computer technology as computer Aided design. AutoCAD is interactive drawing software developed by Autodesk company in America, and is a system tool for two-dimensional and three-dimensional design and drawing; it can be used by users to create, browse, manage, print, export, share information rich design graphics. As general drawing software, AutoCAD is widely used for design work in various industries.
At present, in the practical application process, the characters displayed by the AutoCAD graph come from two types of font files: a suffix SHX file and a suffix TTF file. Wherein:
the SHX file is developed by Autodesk and listed in the compiled file type of AutoCAD and classified into a CAD file, the font file is usually saved in the Fonts folder under the AutoCAD installation directory at the client, and the SHX file can only be referred by the specific AutoCAD program storing the font.
TTF files are a font file format created by apple inc, but are available on both Macintosh and Windows platforms and can be referenced by all programs within the system, including AutoCAD programs. TTF files are saved in a folder of 'system installation disk \ Windows \ Fonts \'.
Because the file format saved by the AutoCAD is DWG and only contains vector image data and metadata of loading drawing, the SHX and TTF font files can not be transmitted and installed along with the DWG file, so that when the DWG file is opened and the editing environment is changed, the abnormal display conditions that the character content of the CAD graph cannot be displayed or messy codes, deformation and the like can occur because the corresponding SHX and TTF font is not installed in the system.
In order to repair such abnormal situations, it is usually necessary for the AutoCAD software operator to manually search for the missing font information and find out that the corresponding SHX font file is copied into the Fonts folder under the AutoCAD installation directory or the corresponding TTF file is to be installed.
Therefore, although some practitioners have also proposed attempts to substitute for the missing font, there have been problems with the character style, character height, character width, and abnormal display of special characters, and the original drawing contents of DWG cannot be restored sufficiently.
In addition, Autodesk provides an electronic transfer tool, and can pack a printing style sheet, an SHX font file, a data link file and the like linked to a DWG document with the DWG document into a compressed file; however, SHX files need to be manually installed after decompression, and for TTF files, Autodesk does not provide the function of transmission with DWG files.

step S2: restoring and installing fonts; when the DWG graphic file is opened, the missing font files are automatically restored from the named object dictionary NOD of the DWG file and are respectively installed in the corresponding directories.
Referring to fig. 2, in a specific application example, the process of step S1 includes:
step S11: opening the AutoCAD program and reading in DWG or DXF documents.
Step S12: reading each style TextStyleTableRecord in a font style table TextStyleTable of the current document through an API of AutoCAD;
step S13: judging whether the font style adopts an SHX font file or a TTF font file for each style TextStyleTableRecord;
step S14: the SHX font file or TTF font file is stored in the named object dictionary NOD.
In a specific application example, in step S13, the font file name FileName and the large font file name BigFontFileName of the TextStyleTableRecord are obtained, and if the FileName string contains "SHX", it indicates that the font style adopts an SHX font file.
In a specific application example, if it is determined that the font style uses the SHX font file, in step S14, the following process is performed:
if a dictionary named FileName or BigFontFileName is already contained in the named object dictionary NOD, then the next TextStyleTableRecord is skipped.
A new dictionary Dict named FileName or BigFontFileName is created in the named object dictionary NOD.
Reading the FileName or BigFontFileName content in the Fonts folder under the AutoCAD installation directory, and storing the Dict content.
In a specific application example, in step S13, if the FileName string does not contain "shx", it indicates that the font style uses a TTF font file.
In a specific application example, if it is determined that the font style uses the TTF font file, in step S14, the following process is performed:
if a dictionary named FileName is already contained in the named object dictionary NOD, then the next TextStyleTableRecord is skipped.
A dictionary Dict named FileName is newly built in the named object dictionary NOD.
Reading the contents of the system installation disk, Windows, Fonts and FileName and storing the contents into the Dict.
In a specific application example, since each style TextStyleTableRecord needs to be operated, the DWG file is saved until all the textstyletablerecords are traversed.
Referring to fig. 3, in a specific application example, the process of step S2 includes:
step S21: and opening the AutoCAD to read in the file data of the drawing file in the supported format.
Step S22: and traversing Fonts folders under the AutoCAD installation directory to obtain all file names with SHX suffixes, and storing the file names into a variable ShxFonts.
Step S23: and calling a system API (application program interface), obtaining the name of the installed font of the system, and storing the name in a variable Ttfonts.

step S25: judging whether each dictionary Dict contains an SHX font file or a TTF font file;
step S26: the installation of the SHX font file or the TTF font file is completed.
Step S27: and restarting the AutoCAD and opening the original document until all Dicts are traversed.
In the specific application example, in step S25, a font name DName of Dict is obtained, such as that "SHX" is included in the DName string, indicating that the font style employs an SHX font file.
In a specific application example, if it is determined that the font style uses the SHX font file, in step S26, the following process is performed:
if the AutoCAD installed SHX font list ShxFonts does not contain the font named DName, the content of Dict is output as the file SFile named DName.
And moving the file SFile to a Fonts folder under the AutoCAD installation directory to complete the installation of the SHX font.
In a specific application example, in step S25, if the FileName string does not contain "shx", it indicates that the font style uses a TTF font file.
In a specific application example, if it is determined that the font style uses the TTF font file, in step S26, the following process is performed:
if the system installed TTF font list ttfffonts does not contain the font named DName, the content of dit is output as file TFile named DName.
And moving the file TFile to a folder of' system installation disk \ Windows \ Fonts \ to complete the installation of the TTF font.
By adopting the method of the invention, accurate restoration can be realized, embedding of two font files of SHX format and TTF format is realized by using Named Object Dictionary (NOD) of DWG file, the font files can be transmitted along with DWG graphic file, and information loss is avoided. When the DWG graphic file is read or edited in a new environment, the missing font file is automatically identified, the missing font file is automatically restored from the NOD and is respectively installed in the corresponding directories, the automatic identification and installation of the missing font file are realized, and the frequent problem that the graphic cannot be normally analyzed due to the missing font file is solved.
