I am using PDFBox to convert PDF pages to images. However, this one particular PDF is rendering too dark. The PDF can be found here https://www.sldttc.org/allpdf/21583473018.pdf.
I'm seeing the same rendering when using the PDFDebugger tool. LibreDraw shows the PDF as CMYK, but I'm not seeing colorspace information in PDFDebugger. Can someone please explain why PDFBox is not rendering this PDF correctly? Thanks, Dave
