CD_METAFILE - CD Metafile Driver (cdmf.h)

+ +

This driver allows the generation of a CD Metafile, a very simple format that includes calls to functions of the CD + library and provides persistence to its primitives.

+ +

Use

+ +

The file is created by calling function + cdCreateCanvas(CD_METAFILE, + Data). The Data parameter is a string that must contain the filename and the canvas + dimensions, in the following format:

+ + 
"filename [widthxheight resolution]" or in C use "%s %gx%g %g"
+ +

Only the parameter filename is required. The filename must be inside double quotes (") + if it has spaces. Width and height are provided in millimeters + (note the lowercase "x" between them), and their default value in pixels is INT_MAX for + both dimensions. Resolution is the number of pixels per millimeter; its default value is + "3.78 pixels/mm" (96 DPI). Width, height and + resolution are real values.

+

Any amount of such canvases may exist simultaneously. It is important to note that a call to function + + cdKillCanvas is required to close the file properly.

+

Images - Be careful when saving images in the file, because it uses a text format to store all numbers and + texts of primitives, including images, which significantly increases its size.

+

Extension - Although this is not required, we recommend the extension used for the file to be ".MF".
