modifying images by PHP?

[charleswong]

Hi,

Can I have develop a PHP program to modify a image format form (e.g. tiff, jpeg) to add some data to these forms?

Take a look at the image functions (requires the GD extension). They cannot use TIFF, but you can use JPEG. Additionally, you may want to take a look at ImageMagick, but I do not prefer it as much as GD.

Might want to search the forums for 'image,' I'm sure you'll find something worth while.

What are you trying to do to the image?

For example, I have a pre-printed application form in hard copy. I have to fill out information in those required fields manually.

Now I want to scan this application form into an image format. Then I want to develop a PHP program to modify this image file to fill out (add) data to required fields (specific locations).

Is it possible?

I know that I can use PDF to do this automation. But the licence fee costs me US$900 per CPU by using PDFlib + PDI. What an expensive licence fee?
