Image Handling

Anon

I have a couple of needs and am struggling to find the code, wonder if anyone can help...

What I need to do is take an image which has been uploaded, check the size of it(pixels not k) and then depending on it's size make either one or two new files from it as thumbnails and then save those into my MySQL db.

Now, I have mastered the uploading and saving into the db, it's just the resizing, twice, and then dumping the result images into the db too where I amk struggling.

Anyone help?

Thanks, much appreciated.

$original = ImageCreateFromGif($img_path);

$original_width = ImageSX($original);
$original_height = ImageSY($original);
$thumb_width = 40;
$thumb_height = 40;

$thumbnail = ImageCreate($thumb_width, $thumb_height);

ImageCopyResized ($thumbnail, $original, 0, 0, 0, 0, $thumb_width, $thumb_height, $original_width, $original_height);

Good Luck!

Is it possible to do the same thing with jpgs?

Yes, you would just substitute ImageCreateFromGif($file) with ImageCreateFromJpeg($file) and ImageGif($thumbnail, $newfile) with ImageJPEG($thumbnail, $newfile).

You must have version 1.8+ of GD installed (later versions won't generate .gifs however). It will include the support for jpegs and pngs if you have their respective libraries installed (libjpeg and libpng). Check out http://www.boutell.com/gd/ for more info on install requirements.

Please bear with me...I am a bit of a newbie at this gd stuff...
Is it compiled so that it also has jpeg support under windoze?
If yes I would definetly appreciate a copy :-)))

TIA

Does anyone know where I can get a copy of gd1.8 ? (So I can run gif and jpeg)
