[iText-questions] Why are the results of" Image.getInstance(URL uRL)" and "Image.getInstance(Image image, Color color)" different ?

[Rochana Attale]

Hi,   I need to generate PDFs with 30-50 pages of images per document. Since these PDFs are generated dynamically for a web application, I am concerned about the PDF generation time and the resulting file size.   First I tried the constructor getInstance(Image image, Color color) and Generated a PDF of 33 pages. The results were as follows:               PDF generation time: 9914 milliseconds             File size: 372 KB   Then I tried Image.getInstance(URL uRL) and generated the same PDF.               PDF generation time: 3616 milliseconds             File size: 4.47 MB   What is the cause of the difference in time and file size in these two cases?   Rochana.
