[magick-users] bad format PDF conversion

[Camille Roux]

Hello

I'm generating pdf from ppt files (in landscape format). The pdf is ok,
but when I convert it to jpg, the image is in a bad format and there's a
blank space above the picture :

Here is the result of "identify" on the pdf:
xxx.p.pdf[0] PDF 720x842 720x842+0+0 PseudoClass 256c 7.5mb 0.260u 0:02
xxx.p.pdf[1] PDF 720x842 720x842+0+0 DirectClass 7.5mb 
xxx.p.pdf[2] PDF 720x842 720x842+0+0 PseudoClass 256c 7.5mb 
xxx.p.pdf[3] PDF 720x842 720x842+0+0 DirectClass 7.5mb 
xxx.p.pdf[4] PDF 720x842 720x842+0+0 PseudoClass 256c 7.5mb 
xxx.p.pdf[5] PDF 720x842 720x842+0+0 PseudoClass 256c 7.5mb 
xxx.p.pdf[6] PDF 720x842 720x842+0+0 DirectClass 7.5mb 

I think the problem is that IM doesn't take care about the resolution or
something like that.
I did the same test for a lot of ppt converted in pdf and there's all
the time the same problem.

I think, I need to know the horizontal and vertical resolution or the
real dimension of the PDF in cm or inches. This way, I could force the
format to a correct size.
Do you know how to do that?


Thank you
