Hi,
Regarding WORDSNET-14892, our product team has completed the work on your issue and has come to a conclusion that this issue is not a bug in Aspose.Words. Your issue (WORDSNET-14892) has now been closed with ‘Not a Bug’ resolution.
PostScript does not support transparency SoftMask. Theoretically it is possible to make some image areas transparent using mask, but it is impossible to create something like “transparency gradient”.
A simple workaround is available for your scenario:
Document doc = new Document(@"C:\Temp\in.doc");
PsSaveOptions opt = new PsSaveOptions();
opt.MetafileRenderingOptions.RenderingMode = MetafileRenderingMode.Bitmap;
doc.Save(@"C:\Temp\out.ps", opt);
Pictures in your document are metafiles, so if you render them as bitmaps, everything should work fine.
Best regards,
