William Fausser commented on PDFBOX-1200:
-----------------------------------------
Additional info:
the ghostscript scructure that creates the "adhoc" colorspace that is then
turne into a stream object is:
/*
* Even though Ghostscript includes icclib, icclib is unusable here,
* because it requires random access to the output stream.
* Instead, we construct the ICC profile by hand.
*/
/* Header */
byte header[128];
static const byte header_data[] = {
0, 0, 0, 0, /* profile size **VARIABLE** */
