MATLAB C/C++ Graphics Library

Restrictions

The MATLAB C/C++ Graphics Library supports most MATLAB 6.0 features, including multidimensional arrays, cell arrays, and structures. However, there are some MATLAB features the graphics library does not support, including:

• MATLAB objects
• MATLAB Java objects
• plotedit command
• propedit command

In addition to these restrictions, the graphics library provides limited support for certain callback coding practices.

Note    The graphics library is subject to the same limitations as the MATLAB Compiler. For example, MATLAB functions that require the MATLAB interpreter, most notably eval() and input(), are not fully supported. See the MATLAB Compiler documentation for information about their restrictions.

Graphics Library Printing Support

If your application uses default print command settings, it should require no modification. The default print command sends the current figure to whatever printer has been set up as the default printer on the system on which your application is running. However, if your application uses print command switches to specify device drivers and other options, be aware that the graphics library supports only a subset of these switches.

For example, the graphics library supports most of the MATLAB built-in drivers, such as the PostScript drivers, but it does not support any of the Ghostscript drivers.

Table 1-3 lists the device drivers supported by the graphics library. For more information about specifying device drivers, see the "Printing MATLAB Graphics" section in MATLAB Graphics documentation.

Table 1-3: Device Drivers Supported by the Graphics Library

Device	Description
-dbitmap	Windows Bitmap (BMP) format (Windows only).
-deps	Level 1 black and white Encapsulated PostScript (EPS).
-depsc	Level 1 color Encapsulated PostScript (EPS).
-deps2	Level 2 black and white Encapsulated PostScript (EPS).
-depsc2	Level 2 color Encapsulated PostScript (EPS).
-dhpgl	HPGL compatible with HP 7475A plotter.
-dill	Adobe Illustrator 88 compatible illustration file.
-dps	Level 1 black and white PostScript.
-dpsc	Level 1 color PostScript.
-dps2	Level 2 black and white PostScript.
-dpsc2	Level 2 color PostScript.
-dwin	Windows black and white printing services. (Windows only)
-dwinc	Windows color printing services. (Windows only)

In addition to device drivers, the MATLAB print command supports several other command-line options that control various aspects of the print job, such as the renderer used. Table 1-4 lists the subset of these options supported by the graphics library. For a complete list of print command options, see the "Printing MATLAB Graphics" section in MATLAB graphics documentation.

Table 1-4: print Command Line Options Supported by the Graphics Library

Option	Description
-adobecset	Use PostScript default character set encoding.
-append	Append to existing PostScript file without overwriting.
-cmyk	Use CMYK colors in PostScript instead of RGB.
-noui	Suppress printing of user interface controls.
-rnumber	Specify resolution in dots per inch (dpi).
-painters	Render using Painter's algorithm.
-zbuffer	Render using Z-buffer.

Unsupported Application Coding Practices

The graphics library does not support certain graphics M-file coding practices that are supported in the MATLAB interpreted environment. For example, MATLAB allows you to specify variable references and assignments in callback property strings. The graphics library does not support this coding practice in stand-alone graphics applications.

See Chapter 3, Troubleshooting for more information about unsupported coding practices and how to work around them.
