Subject Problem converting a shaded shape to another format
Date Thu, 12 Feb 2015 16:31:25 GMT
I have been attempting to find the cause of this problem for at least a day and have tried
Google searches and your site https://pdfbox.apache.org

Originally I was attempting to convert the PDF to TIFF, but the shading does not get copied
to the converted file, although it does to the file ShadedShapes.pdf_COPY.pdf.

This is produced by loading the PDF ShadedShapes.pdf into a PDDocument and then saving it
to the output file. This was done to check that the shading was not lost during the loading
process.

When attempting to convert to PNG (or TIFF), the shading is lost so I assume the shading is
a non-stroking colour.

I am particularly keen to have a solution to this, as in all other respects, the conversion
to TIFF appears to have a very accurate reproduction.

I have not tried this with the Version 2 of PDFBox, as I note that the PDPage  method convertToImage
is not available and without any apparent information on how to use the collection of classes,
apart from other user contributions, it is difficult to work out how to use this very useful
library.
