Problems with image to PDF conversion

[squirrel]

Hi everybody,

I am using ImageMagic in PHP to convert image files (JPG, GIF, PNG) to PDF. At first I thought this was no problem and I was able to set everything up easily.

PROBLEM:
Some images (some resolutions, some dimensions) convert to PDF but then display an empty or a misplaced image in the resulting PDF. Most images will convert correctly though...

TASKS:
- rotate image by -90 degrees
- center image on page
- force image into A4 format and size

CODE:
I am using the following command to perform the tasks:

Code: Select all

convert -rotate -90 -gravity center -page A4+0+0 source.jpg target.pdf 2>&1

QUESTIONS:
1.) What could possibly the problem why *some* images just won't convert correctly? Where is my mistake?
2.) Do I have to RESIZE or SCALE the images in any way to achieve what I want? Am I missing something?


Thank you very much in advance for any ideas!

SOLVED... kind of...

I took the "-gravity center" option completely out of the command and... now every generated PDF show the original image! The only remaining issue is that the image is always aligned to the lower left corner of the page. That was actually the reason why I inserted the "-gravity center" option in the first place.

Cheers!
