Is there a good reason your output files are in JPEG format? EPS is a vector format, while JPEG is a lossy-compression bitmap format which is specifically optimized for photographs – i.e., images consisting of vaguely defined patches of variable color, as opposed to sharply defined solid areas, which is what vector images consist of.
22/07/2014 · convert convert.pdf -scale @550000 PNG8:convertedPDF.png My command above works wonderfully on some pdf’s but on others it does not as shown in the picture. There is not enough detail in convertedPDF.png to identify a basic drawing shape.
A variety of different commands are included with the ImageMagick distribution that I divide into “analysis” and “editing” tools. For this article, let’s stick with the analysis tools. Let me start by showing you how much more information it offers on a typical image file than the standard Linux command line.
How can I generate an A4 PDF, from an a4@300 PPI bitmap, using pdflatex (or if there is a better alternative to pdflatex, which one?) You can use the standalone class to get a PDF which is just as large as the the image, which gives you A4 if the image is in the size of A4.

I suspect there is no actual bug here, and certainly not a Ghostscript one. The problem is with the interpretation of 0. Your monitor can’t display CMYK inks, and so the CMYK in the file need to be converted to RGB for display.
ICC Profiles. PDFs optimized for physical printing often use the CMYK color space. On the web, however, the de facto color system is sRGB. By default, DSpace’s ImageMagick-based thumbnailing system will create thumbnails that use the same color space as the source PDF.
ImageMagick is behaving as designed. To convert from one colorspace to another, you need two profiles. If the source image already includes a sRGB profile, adding -profile USWebCoatedSwop.icc to the command-line converts the colorspace to CMYK and that is reflected in your JPEG image.

The seemingly superfluous 2nd call of convert is indeed due to unpaper which cannot deal with tif, and because the unpaper output did was not properly processed by tesseract. In version 0.1.6, -unit PixelsPerInch has been added to the convert options, and the order of the convert command line arguments has been changed according to the recommendations.
