问题 I am trying to create code to export out the images within a PDF using iText Version 7.19. I'm having some issues with Flate encoded images. All the Flate encoded images from the Microsoft free book I'm using as an example (see Moving to Microsoft Visual Studio 2010) always coming out pink and depending upon how I try to copy the bytes they can come out distorted.
