Of course you can use the "ImageMagick-6.6.1-Q16-windows.zip" package. (Why should they provide a binary that doesn't work? :wink:) As the description says, the zip file is basically the Q16 static Win32 package - without installer. @Ayusman: You should have tried this after downloading (a...

Do you know how can I just crop a PDF file With Adobe Acrobat? :wink: I wouldn't be too optimistic about getting solutions for this - that's an ImageMagick board, you know.. I'm also still a bit unsure what's the purpose behind this. Do you want that other people don't see the 'borders' (of the Med...

Thanks but can you tell me will it effect the quality of image in printing..? What is "it"? - In your example, the resample does simply nothing. - Changing the density doesn't alter the quality of the image (the pixels) itself - but it will change the print size. When you change the densi...

When you first change the density manually to 300dpi, you don't need the "-resample".

Me thinks he wants to edit the PDF, but keep the elements vectorial..?
@omman95: That's not possible with ImageMagick. Read this:

First: You probably have to update Ghostscript. I'm using current versions (Ghostscript 8.71, ImageMagick 6.6.1-5) and have better results/colors (with a simple "convert -density 300 test.pdf[0] output.png" command): http://www.imagebanana.com/img/m84z7a2n/test300dpi_im.png But: There is s...

This is a known behaviour of Ghostscript. See here:
http://www.imagemagick.org/Usage/formats/#ps_reading

The 'ps:color' delegate is used rather than 'ps:alpha' by default because the 'pngalpha' ghostscript device only supports a one page/one image and PDF's generally are multi-page.

Getting correct colors from PDFs can be a difficult task sometimes - as this depends more on Ghostscript (not so much on ImageMagick).
Can you upload your PDF?

You have to insert "-define pdf:use-trimbox=true" into your ImageMagick command - as Fred (fmw42) told you. Did you try that?

Great! Thanks!

There is still some rounding issue IMO. Example: Again, I have a 300dpi PNG. "identify -verbose" shows the correct info for that: Resolution: 118.11x118.11 Print size: 21.607x30.3361 Units: PixelsPerCentimeter "identify -verbose -units PixelsPerInch" correctly shows the converted...

PNG only supports pixelspercentimeter. IM converts density from pixelsperinch if supplied that way to the correct density at pixelspercentimeter when creating a PNG. Yes, but there should be a way to recreate the 'PixelsPerInch value' IMO. When I have a 300dpi image, most programs do report the fil...

The only other IM command that I know of that makes the process quicker is "identify -verbose -ping <file>". But this will render the type/depth info useless. For the 'create-date', I think I would just use "dir". And did you try "%[colorspace]" (or maybe "%r"...

For large JPGs, you can usually add a '-define jpeg:size' parameter (unless you need the full statistic/histogram). So, such a command will be very quick on your file: identify -verbose -define jpeg:size=64x64 page_0001.jpg But as you're using an older IM version, the following command could still b...

I've tested with IM version 6.6.1-4. My problematic PSD files all work now!
Thanks again - for that great piece of software and for the fix!
