Hi Eric. Welcome to TSDN!
The GD functions will work on most JPEG, PNG and GIF images. They also have support for some BMP formats, tho I have never been able to find much use for them.
There is no way to give exactly the functions you will need, as I do not know what you are trying to do, but all the GD functions are listed in the above link.
If that does not work for you, you could try a Google search for ImageMagick. I have never used it but it is supposedly superior to GD in many ways. -
Hi Eric
If your picture is 300dpi, I'd suppose saving the picture will still produce a 300 dpi picture unless you alter the size of the picture.
I would advise you not to use a php-method to toy around with images used for printing (if that is your objective). In this case i think Java would be better (don't know how much better tho)
I found this topic discussing the same subject, you might wanna check it out linkComment
