Randall Hopper:
| But then when we get to rasterization and clipping down here:
|
| DXRender -> ... _dxfPaint -> ... -> _dxf_Quad -> _dxf_zclip_quads
|
|in _dxf_zclip_quads, the TRYCLIP macro (zclip.h) is used 6 times. It
|invokes the other macros SPLIT and ADDPT (also zclip.h). These macros
|assume that if there is no colormap (xf->cmap = NULL), then the colors
|must be RGBColor structs (floats) which is not correct.
|
| The work-around is not to Render anything with 24-bit RGB colors,
By way of confirmation, this unsigned char[3] -to- float color conversion:
Mark("colors") ---> Compute("$0/255.0") ---> Unmark()
inserted before the data gets to render seems to avoid all encountered
memory problems.
