My issues involves ImageMagick behavior with .pdf files. I don't work in the printing industry, so I apologize in advance for not knowing the proper terms.
I have a set of .pdf files for magazines. These files are apparently the same files that were sent to the print shop. For example, the color space is CMYK. I am using IM convert to generate .jpg page images from these files. I have two .pdf files have a 2-page landscape "spread" for the outside cover, so that the front & back covers are on the same landscape page. This makes sense for printing. One of these files has 2-page landscape spread for the inside covers as well. The other file treats the front/back inside covers as individual portrait pages. I am puzzled / struggling with ImageMagick (ghostscript?) behavior with these files. I have observed the following: * for the file with only the outside cover spread, the spread shows up only at the beginning. That is, it only shows up as a single image in the .pdf file * for the file with both outside and inside cover spreads, the spreads show up both at the beginning and at the end. For example, when I run "identify" the spreads show up both at the beginning and at the end of the list of image frames. I have observed that Adobe Reader also treats these files specially, so I assume that there must be directives in the .pdf file which describe this situation. My problem is the seemingly inconsistent behavior with ImageMagick / Ghostscript, where sometimes the cover spread is duplicated at the back and sometimes it is not. Q: Any advice on how to handle this issue would be greatly appreciated.
