I have a PDF file within which there are some polygons filled with
'Tilling Color Pattern'. I know how to retrieve the 'PatternColor'
object, but how to use this object and draw to canvas with GDI?
Note: The pattern displays blue, but the color I retrieved is always
black.
I retrieved the SDF object from 'PatternColor' as below:
{
/GS1 gs
q
32 0 0 -128 0 128 cm
/Im1 Do
Q
}
It seems the pattern cell is a masked image. How can I get the mask
image stream?
I would like to upload the PDF file to this thread for you, how to do?
