on version 6.3
I using this command line:
convert "test1.png" -crop 3307X4677+0+0 "result.pdf"

I have updated to 6.5
and now the Crop command not function with pdf destinations

why?

Add +repage just before result.pdf. Does that give you the expected results?

ok now.

thanks!

only for understand, why +repage need on pdf and not for png result?

It is needed for all formats to reset the virtual canvas from the original image size to the new size

see

http://www.imagemagick.org/script/comma ... s.php#crop
http://www.imagemagick.org/Usage/crop/#crop_repage

Though many formats ignore or don't use a image 'offset' or canvas normally.

JPEG does not save it
PNG only saves offsets but few programs use the offset

and so on.

Obviously the PDF coder does use it. Probably for positioning images on a page.

In any case +repage resets the offset and sets the page size to the same size as the image itself.


Does anyone have any other information on how PDF images use the pafge/canvas infomation?
