DO NOT REPLY [Bug 45027] New: Color 'blue' does not render correctly
when '
fo:external-graphic' is present
https://issues.apache.org/bugzilla/show_bug.cgi?id=45027
Summary: Color 'blue' does not render correctly when
'fo:external-graphic' is present
Product: Fop
Version: 0.93
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: pdf
AssignedTo: fop-dev@xmlgraphics.apache.org
ReportedBy: an_tonio@mail.com
CC: an_tonio@mail.com
I have tried to produce pdf documents either with blue text or embedding a svg
graphic with blue color in it (#0000FF, or rgb(0,0,255)), but this color does
not render correctly. However, when the embedding option is removed, blue text
does fine within the 'color' option in the fo/xsl document.

issue happens with Adobe X 10.1.3 on the Mac, does not happen with Mac's own
Preview. seems an Adobe issue to me, just like the dull colors issue.

jeremias, does this bug need to stay in the needinfo state, or should it be
moved to resolved?

Well, the bug is on NEEDINFO because what happens here is not understood, yet.
If anything, this marks a known problem but IMO it shouldn't be closed.

Actually I realized this problem when I printed a document using Acrobat 5,
(the blue was not printed correct). As you said, in the screen of Acrobat 5 the
blue renders accurate but it doesn't in the printer. Acrobat 8 is in this sense
‘more WYSIWYG’.

Thanks for the test files. I can now reproduce the effect. This is really
strange. What I can tell you is that the text painting code in PDF doesn't
change if I remove the opacity from the rectangle being painted AFTER the text.
But what's important to note is that I've seen the effect only on Acrobat 8 but
not on Acrobat 5 or GhostScript/GhostView. At the moment I have absolutely no
clue why this happens. I'm attaching the two PDF files (with compression turned
off) to demonstrate the difference. Maybe someone could check if the effect
occurs on other Acrobat versions like 6 or 7 and report back here.
As a side-note: It's a bit strange that Batik paints the transparent rectangle
as a bitmap as this is such a simple element. That could probably be improved
somehow. That accounts for the increase in size when opacity is turned used,
but it doesn't explain why the text color changes to a darker blue. There's
also an inconsistency about how the coordinate system for the rectangle is set
up between the two variants. But again, this doesn't account for the color
change.

Please attach an FO file that demonstrates the problem. I can't reproduce the
problem with your description alone. Furthermore, can you elaborate on what you
mean by "does not render correctly"?

Hello FOP community
I have checked the problem again (Bug #45027) and actually this problem resides
in the SVG document.
When the ‘opacity’ attribute (with a value less than 1) is included in a
determinate shape element, this affects the color of the text, even if such
text lies outside the shape range. That is what I mean ‘does not render
correctly’.
As an example, I attached a SVG file with blue text and a rect element with an
opacity attribute less than one. If you embed this with a FO/XSL file, the text
won’t be blue anymore.
Perhaps this issue belongs to the ‘SVG Component’, but it is up to you to
decide this...
