thanks, wow
I did a very quick test by adding this to my rendering test
{code}
BufferedImage image = renderer.renderImageWithDPI(i, 96, ImageType.ARGB);
BufferedImage imageWhite = new BufferedImage(image.getWidth(),
image.getHeight(), BufferedImage.TYPE_INT_RGB);
Graphics2D g = (Graphics2D) imageWhite.getGraphics();
g.setBackground(Color.WHITE);
g.clearRect(0, 0, image.getWidth(), image.getHeight());
g.drawImage(image, 0, 0, null);
g.dispose();
image = imageWhite;
// old code:
//BufferedImage image = renderer.renderImageWithDPI(i, 96); // Windows native
DPI
{code}
and the differences are amazing... I'll have to check each one of them.

{quote}some blendmodes don't work properly against the page background
{quote}
The "unmarked space" simply means a raster buffer (like BufferedImage) that is
initially fully transparent. This makes the blend modes work. No new graphics
engine is needed.
See how Mozilla PDF.js has implemented it
[here|https://github.com/mozilla/pdf.js/blob/ea3d8450d218dd53619c72c934547fe57f22530f/src/display/canvas.js#L731].
If a PDF page uses any blend modes [other than
Normal|https://github.com/mozilla/pdf.js/blob/ea3d8450d218dd53619c72c934547fe57f22530f/src/core/evaluator.js#L226],
PDF.js renders everything on a fully transparent RGBA canvas. Finally when the
page has been rendered, PDF.js draws the RGBA canvas on a white canvas.
When rendering graphics like this in a fully transparent buffer, you are
actually implementing _page groups_, which are explained in the PDF 32000
standard in section 11.4.7.

[ https://issues.apache.org/jira/browse/PDFBOX-4095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16350678#comment-16350678 ] Tilman Hausherr commented on PDFBOX-4095: - Thanks... I tested with many PDFs, there are a lot of differences, some are rendered incorrectly (e.g. [^gs-bugzilla690477.pdf])... maybe start with [http://www.eci.org/_media/downloads/altona_test_suite/eci_altona-test-suite-v2_technical2_one-patch-per-page_x4.pdf] there is an exception (IOOB) on one of the last pages. Of course I can't say for sure if it is a bug in your change, or if your change uncovered bugs that have been there already. It might also be possible that I messed up something while inserting your code. If possible, try attaching real diff / patch files, this avoids any human error. > Non Separable Blend Modes implementation(HUE, SATURATION, COLOR, LUMINOSITY) > > > Key: PDFBOX-4095 > URL: https://issues.apache.org/jira/browse/PDFBOX-4095 > Project: PDFBox > Issue Type: Improvement > Components: Rendering >Affects Versions: 2.0.8 >Reporter: savan patel >Priority: Major > Attachments: BlendComposite.java.patch, BlendMode.java.patch, > COSName.java.patch, blendmodes.pdf, gs-bugzilla690477.pdf, > gs-bugzilla697433-1.pdf > > > I have a patch for implementation of non separable blend modes... -- This message was sent by Atlassian JIRA (v7.6.3#76005) - To unsubscribe, e-mail: dev-unsubscr...@pdfbox.apache.org For additional commands, e-mail: dev-h...@pdfbox.apache.org
