Tilman Hausherr updated PDFBOX-615: ----------------------------------- Attachment: GouraudShadingContest.java Type5ShadingContext.java Type4ShadingContext.java GouraudTriangle.java Vertex.java Type5ShadingPaint.java Code for type 4 and (new) 5 shading, refactored. The two changes in other classes described previously must be done analog for type 5. The background problem is not just "not knowing what to paint there" because this time (see lattice1.pdf) there is text around the pattern which is missing in the rendered image. Any help is appreciated. > shfill operator needs implementation > ------------------------------------ > > Key: PDFBOX-615 > URL: https://issues.apache.org/jira/browse/PDFBOX-615 > Project: PDFBox > Issue Type: New Feature > Components: PDModel > Reporter: Daniel Wilson > Assignee: Daniel Wilson > Attachments: Centerplan.pdf, DECAHED.pdf, GouraudShadingContest.java, > GouraudTriangle.java, Type4ShadingContext.java, Type4ShadingContext.java, > Type4ShadingPaint.java, Type5ShadingContext.java, Type5ShadingPaint.java, > Vertex.java, axial-input-after.png, axial-input-before.png, axial-input.pdf, > bugzilla843488.pdf, bugzilla843488.pdf-1.png, color_gradient.pdf, > color_gradient.pdf-1.png, decahed.pdf-1.png, input.pdf, input1.png, > pdfbox-1.8.patch, pdfbox.patch, pslib-shading.pdf, radial-input-after.png, > radial-input-before.png, radial-input.pdf, shading_pattern.pdf, > shading_pattern.pdf-2.png, trityp4.pdf-1.png > > > I have a PDF file (for which I do not yet have release permission) that uses > the "sh" operator, equivalent to PostScript's shfill (per PDF spec 1.7 page > 987). > Adobe provides implementation guidance in a 78-page document at > http://www.adobe.com/devnet/postscript/pdfs/TN5600.SmoothShading.pdf#17 > I will be trying to add this functionality this week, but if anyone has > hints, suggestions, etc. they are most certainly welcome! -- This message was sent by Atlassian JIRA (v6.1.5#6160)
