The function sets optional flags affecting the graphics state, coordinate handling, as well as color
and image conversion rules. If the parameter Reset is true, the new flags replace current flags. If set
to false, the flags are combined with the current flags.
Flag
Description
gfCompatible
The graphics state is fully compatible to earlier versions of
DynaPDF.
gfRestorePageCoords
If set, the current base coordinate system like bottom or top down is
saved and restored with the graphics state.
gfRealTopDownCoords
This flag is reserved for future extensions. It is not implemented
yet.
gfNativeBlackWhite
If set, RGB black or white is not converted to DeviceGray. This flag
affects text and vector graphics but no images.
gfUseImageColorSpace
If set, the active color space is ignored when inserting an image. The
color space is taken from the image file instead. See also "Color
spaces and Images".
