Q: How is the quality parameter defined when using JPEG2000 compression in jPDFOptimizer? This is the sample code I am using to compress existing images to JPEG2000 within PDF documents using jPDFOptimizer. imageoutput.setCompression(ImageOutput.CO_JPEG2000); imageoutput.setCompressionQuality(0.8f);imageoutput.setCompression(ImageOutput.CO_JPEG2000); imageoutput.setCompressionQuality(0.8f); The quality setting for JPEG200 compression is used to calculate the data rate (bits per pixel). The range for this […]

How to set the quality parameter when optimizing PDFs using JPEG or JPEG2000 compression
Q: We are using jPDFOptimizer, your Java library to optimize PDF documents. We are getting inconsistent results when compressing using JPEG2000 with the quality parameter. Sometimes the images are well compressed with a quality of 0.8, sometimes we have to use a quality of 0.2 for what appears to be the same results. A: This […]
