Hi,

we are using identify to retrieve the dimension of pdf files and the precision is not exact enough for us.

the command we are using is "identify -format %w#%h"

In the source code of "icoders/pdf.c" i found that you will round the values.

Code: Select all

/*
      Set PDF render geometry.
    */
    page.width=(unsigned long) (bounds.x2-bounds.x1+0.5);
    page.height=(unsigned long) (bounds.y2-bounds.y1+0.5);

So my question is it possible to retrieve somehow the original values without rounding them ? Or possible to retrieve the bounds ?

Any help would be welcome

We'll add a patch to ImageMagick 6.3.1-6 Beta to return the high-resolution bounding box for Postscript and PDF images. It will be stored as an image attribute so use

identify -verbose

to retrieve it. The updated Beta will be available by tommorrow.

First of all thanks for your fast response and this very quick enhancement. It will increase my trust in imagemagick and to this great community of developers.

I have one question to "-verbose" left. is the speed of "-verbose" behaviour same than "-format" ?

Thanks a lot

Here's what you want:

identify -format "%[HiResBoundingBox]" demos/verizon.ps

thanks a lot
