Summary: PDFGraphics2D addImage method: image in PDF look as very
low resolution image
Product: Fop
Version: all
Platform: All
OS/Version: All
Status: NEW
Severity: minor
Priority: P3
Component: pdf
AssignedTo: fop-dev@xmlgraphics.apache.org
ReportedBy: fabio_sassi@libero.it
[PATCH]
In PDFGraphics2D image are rescaled 2 times in the same way.
First is rescaled by java.awt.Graphics2D and put in BufferedImage
that will used to write PDF code. Second is rescaled by trasformation
matrix in PDF code.
This will cause a resulting image that have very low resolution (pixelized).
Before look at PDFGraphics2D code I try also to change DPI but this has
not effect.
