CD_PICTURE - CD Picture (cdpicture.h)

+ +

This driver allows the creation of a CD Picture. It store primitives and + attributes in memory that can be played and resized in any other driver. It + does not includes clipping and WriteMode.

+ +

Use

+ +

The file is created by calling function + cdCreateCanvas(CD_PICTURE, + Data). The Data parameter is a string that + can contain the resolution in the following format:

+ + 
"[resolution]" or in C use "%lg"
+ +

Resolution is the number of pixels per millimeter; its default value is + "3.78 pixels/mm" (96 DPI).

+

The canvas size is automatically calculated to be the bounding box of all the +primitives inside the picture.

+

Any amount of such canvases may exist simultaneously. It is important to note that a call to function + + cdKillCanvas is required to release the picture memory.

+ +

Attributes

+ +
  • + + WriteMode: does nothing.
    • +
  • FontDim: + uses a size estimator, returning approximate values.
    • +
  • + TextSize: uses a size estimator, returning approximate values.
