This is a more efficient and less memory intensive way to query if an imageGexists and what its size is. Note, only the size of the first image in%a multi-frame image file is returned.

<

-size <width>{%}x<height>{%}{+offset}{!}"
width and height of the image.

Use this option to specify the width and height of<raw images whose dimensions are unknown such as GRAY,ARGB, or CMYK. In addition to width and height, use@-size to skip any header information in the image or tellKthe number of colors in a MAP image file, (e.g. -size 640x512+256).

   192x128
   384x256
   768x512   1536x1024   3072x2048
N
Finally, use this option to choose a particular resolution layer of a JBIG$or JPEG image (e.g. -size 1024x768).



-verbose/
print detailed information about the image.

This information is printed: image name; the image classG(DirectClass or PseudoClass); the total number of uniqueFcolors; whether there is a matte associated with the image; the numberGof runlength packets; the image size; the depth of the image; the imageAformat; the image scene; and finally any image comment.
