Editing jpg files.

[arildr]

I have 6000 jpg's and need to edit them and than edit new pictures in this way.

Lets say i have a picture called test_1.jpg 200x100 pixels

Today i use Gimp and do this:

1. Remove the "image comment" and replase it with "This is my picture"

2. Save it with 85% quality

3. Make it 200x200 centered and flaten ( remove transparent )

4. Resize to 100x100 and saves it as test.jpg 85% quality

 

This way it will take years, so a PHP prog would make my life easyer.

...or do i have to make a Gimp script?

 

( May the force be with me )

PHP can do this.

 

See the doc: http://php.net/manual/en/book.image.php

 

Use imagecreatefromjpeg() then the rest is quite simple from the docs.

 

JPGs don't have transparency, so how can you remove it?

Irfanview has a lot of advanced batch operations:

Additionally, you can use the PEL library to edit the jpg's exif data.
