- @doc: pixmap
- @keyterms:
- pixmap object class
- @title:
- pixmap class
- @type:
- class
- @short:
- This class provide a pixmap.
- @inherits:
- [class]object[/class]
- [class]widget[/class]
- @description:
- The pixmap class is an off-screen, pixel-based paint device.
- @functions:
- !fn: $fill(<widget:object>,<x_offset:integer>,<y:offset>)
- Fills the pixmap with the widget's background color or pixmap.[br]
- Note that x_offset, y_offest are offsets in the widget.
- !fn: $resize(<width:integer>,<height:integer>)
- Resizes the pixmap to w width and h height. Set wh or hg to 0, to have a null pixmap.
- !fn: $scale(<sx:real>,<sy:real>)
- Scales the pixmap by sx horizontally and sy vertically.
- !fn: $rotate(<a:real>)
- Rotates the pixmap by a degrees.
- !fn: $load(<file_name:string>)
- Load a pixmap from the <file>.
- !fn: <integer> $height()
- Return the height of the pixmap.
- !fn: <integer> $width()
- Return the width of the pixmap.
