The computational time to render PDFs with transparency needs improvement. Several performance problems are summarized in an attached report. The problems are not restricted to any particular operating system.
Created attachment 5959 [details] PDFTransparencyPerformance.pdf The performance problems are summarized in the attachment. Solutions are suggested.
Created attachment 5960 [details] pdf_trans_performance.xls The spreadsheet is referenced in the PDF report. It contains timings for several PDF files that contain transparency and compares to rendering the files with transparency disabled. The referenced files are good choices for testing as the performance problems are resolved.

Closing this as Robin has made some significant speed-ups in transparency with his templates and the SSE code is giving good acceleration.
