Resample and make transparent or vice versa

A good example...

Can you please write me why following code is not working?

that's another question...

No it's not bugada. That code that you showed me is too long. Could you please check my one?

Thanks

Try this code is slighy modified. I cannot check if work beacuse my server hasn't gd library.

Only a thing: remember that if you are using gd library v1.6+ you haven't anymore imagegif(), so you may use imagepng()

It didn't work bugada. I am using this one, why it does not work? I want to minimize my image to half size.

Regards

imagecolortransparent( $im, $fill );
$image_p = imagecreatetruecolor($max_box_width / 2, $max_box_height / 2);
imagecopyresized($image_p, $im, 0, 0, 0, 0, $max_box_width / 2, $max_box_height / 2, $max_box_width, $max_box_height);

No bugada, it still looks awful. Do you have any other solution?

Cheers

I am using small fonts and small images, so I need something regarding that.

Thanks
