New user here! Downloaded the V11 trial as I believe this may be a suitable product fro what I'm trying to do. I'm looking to convert PDF to PNG but preserving the transparent background in the PDF, as found if the PDF is opened in PhotoShop. So far the functions appear to render a solid background (white). Have been trying the DLL version on windows. DPLLoadFromFile DPLRenderDocumentToFile These work with both the gdi and DPLR renderers using DPLSelectRenderer but I just get a PNG without an alpha channel original PDF is RGB + alpha I'm obviously missing something simple but searching the help and forums is bringing nothing up  Alan |
