DgGlyphTone_Threshold *pixel,
DgInt32 shapeIndex,
DgInt32 cellSize,
void *privData

);

Summary

Type definition of a function that pre-processes pixels. In particular, an entry in a threshold array. Such functions are intended to be called before the threshold array is sorted.

Parameters

pixel		Pointer to the pixel in a threshold array that is being processed
shapeIndex		The index of the shapes in this glyphtone design.
cellSize		The size of a glyph cell.
privData		Private data of the glyphtone mark

Output Parameters

pixel

Pointer to the pixel in a threshold array that is being processed.

Return Value

• DG_TRUE This pixel shall be included in the threshold array
• DG_FALSE This pixel shall be excluded in the threshold array
