My issues relate to convert PDF -> JPG SUMMARY
Q: Given a .pdf file with a mixture of individual pages and 2-page-spreads, how can I use ImageMagick convert to generate .jpg files of individual pages? BACKGROUND I have an archive (college alumni magazines) of .pdf files that I need to convert to .jpg page images. I don't know what tools were used to create these .pdf files. In Adobe Reader the .pdf properties say PDF Producer:Creo Normalize jTP The magazines are essentially 8.5x11. I would like to use ImageMagick convert to generate individual .jpg files of the individual page images. The colorspace on the .pdf files is CMYK, which makes me wonder/assume that these are the actual files which were sent to the print shop for printing the paper copies of the magazines. I was able to use -colorspace RGB to correct the colorspace on the output .jpg files. PROBLEM Some of the .pdf files contain a mixture of 8.5x11 portrait pages and 11x17 landscape 2-page-spreads. I can confirm this by opening the files in Adobe Reader. When I run them through "convert" these 2-page-spreads are getting compressed horizontally into a single 8.5x11 portrait page. I assume that convert is seeing the 8.5x11 size on the first page and is making all subsequent pages fit that size. The command line that I am using is: convert -quality 70 -density 300 -colorspace RGB TLN20100801.pdf 300dpi70/tulane_magazine_201008_%04d.jpg Advice/recommendations from the IM gurus would be greatly appreciated.
