GraphicxSP is an extension of the graphicx package. GraphicxSP embeds
the graphic in the PDF document once, and allows the document author to
use and re-use that same graphic without significantly increasing the
file size. Additionally, GraphicxSP supports Adobe transparency imaging
model.
GraphicxSP is useful for repeated graphics like backgrounds,
watermarks, company/universit logos and so on. The graphics produced
by GraphicxSP appears to be clearer at high zoom factors than the same
graphic produced by the classic Graphic package. Restriction:
This package requires that the PDF be created by Adobe
Distiller, version 5.0 or greater for graphics without transparency,
version 5.0 with transparency.
