drawlist_ic -- create drawlist BOOPSI objects
imageclass
None.
This image class can create custom scaled glyphs via a
"drawlist". The drawlist is an array of drawing directives
such as lines, areafills, etc. All coordinates are based
on an imaginary grid of a user specified size, then
ScalerDiv() is used to scale these coordinates to the desired
image size to be rendered. This is a lower level class utilized
by glyph.image, if you create some interesting drawlist, please
consider passing them on to others, or to us for inclusion.
OM_NEW -- Create the drawlist image. Passed to superclass, then
OM_SET.
OM_GET -- Get object attributes. Passed to superclass first.
OM_SET -- Set object attributes. Passed to superclass first.
OM_UPDATE -- Set object notification attributes. Passed to
superclass first.
IM_DRAW -- Renders the images. Overrides the superclass.
IM_DRAWFRAME -- Renders the images scaled to thee frame size.
Overrides the superclass.
All other methods are passed to the superclass, including OM_DISPOSE.
DRAWLIST_Directives (struct DrawList *)
An array of drawlist directive structures are passed
to specify the vectors and render operation. The last
entry must be DLST_END!
struct DrawList
{
WORD dl_Directive;
WORD dl_X1, dl_Y1;
WORD dl_X2, dl_Y2;
WORD dl_Pen;
};
The following directives are supported;
DLST_END - End the directive list.
DLST_LINE - Render a line from dl_x1,dl_y1 to dl_x2,dl_y2
DLST_RECT - Cause a RectFill() of size dl_x1,dl_y1,dl_x2,dl_y2
DLST_LINEPAT - Set the line pattern to value held in dl_Pen
DLST_FILLPAT - Set the fill pattern to value held in dl_Pen
DLST_LINESIZE - Set the drawlist line thickness via dl_Pen
DLST_AMOVE - AreaMove() using dl_x1,dl_y1
DLST_ADRAW - AreaDraw() using dl_x1,dl_y1
DLST_AFILL - Cause the AreaFill() operation
DLST_FILL - Flood() an area.
DLST_ELLIPSE - AreaEllipse()
DLST_CIRCLE - AreaCircle()
DLST_BEVELBOX - currently unsupported (alpha function removed)
DLST_ARC - currently unsupported
DLST_START - currently unsupported
DLST_BOUNDS - currently unsupported
Defaults to NULL.
Applicability is (OM_NEW, OM_SET, OM_GET)
DRAWLIST_RefHeight (WORD)
Reference height of the drawlist imagary grid.
Applicability is (OM_NEW, OM_SET, OM_GET)
DRAWLIST_RefWidth (WORD)
Reference width of the drawlist imagary grid.
Applicability is (OM_NEW, OM_SET, OM_GET)
