Major Speed/Size when using SetCompressionForColorImage

[SarrasiM]

Good day,

We've been creating PDF with large grayscale image (plan) and we discovered that setting SetCompressionForColorImage to PdfCompressionJPEG2000 will cause a major slow down in processing as well as a very huge PDF.

For instance:

214 JPEG, 1.84GB

Total PDF size using SetCompressionForColorImage: 3 013 585MB
Total time using SetCompressionForColorImage: 51 minutes

Total PDF size WITHOUT using SetCompressionForColorImage: 620MB
Total time WITHOUT using SetCompressionForColorImage: 3 minutes

This is on v11. Any idea why such a difference?

Thank you,

[SarrasiM]

Any idea?
