[Typo3-dev] function imagecopyresized

Hi Thomas,

The whole function provides a replacement for the imagecopyresized function
in PHP. I don't know why but Kasper expects this not to be working with GD2,
therefore he created this alternative function.

However I have found out that this would make absolutely no problems and
work fine even with GD2!

You can fix the problem by commenting out all the stuff from 'if(...) {' up
to the else statement and just leave this single line there:

imagecopyresized($im, $cpImg, $Xstart, $Ystart, $cpImgCutX, $cpImgCutY, $w, $h, $w, $h);

Hope this helps. I hope Kasper will read my mail and add a switch to the
config where one can choose if he wants to use the replacement or not.

Cheers - michael

Dear Kasper,

I am close to finish fully working Debian packages that contain full GIF
support.

My problem is that there is one outstanding problem with the alternative
imagecopyresized function you have created.

I don't know why, but I couldn't make it work. Apache simply died before
sending any output. The die happens in this function, but I don't know more
about that.

Anyway. After a few hours of playing around with that, I have finally found
out that PHPs original imagecopyresized function would be fully working! (At
least in the install tool - there are no problems with the checks.)

Since this is hardcoded and TYPO3 never uses this function when GDlib2 is
used, I would like to ask you to to add a new option where I can override
this.

Thanks in advance.

Kind regards
- michael
