TYPO3 Core

I am unable to reproduce this with an 800X600 image. Your given TS leads to two different files (and hashes) in current 4.3 trunk (revision 3978).

Attached your patch from the core list, if the issue is still valid but just doesn't occur in my current setup.

I can confirm this bug on TYPO3 4.0.12.
If have something like this:
file.width = 900c
file.height = 100c-100
and change it to
file.width = 900c
file.height = 50c-100
It will still output an image with 100pixels in height.

If I then change it into:
file.width = 900c
file.height = 50c-99
I will get an image with 50pixels in height.

If I go back to:
file.width = 900c
file.height = 50c-100
I will get 100 pixels again...

I am still unable to reproduce this in trunk (r5064). Full TS used in test:

page.10 >
page.10 = IMAGE
page.10 {
file = fileadmin/img/testpic.png
file.width = 900c # Changing from 100c-100 to 50c-100 leads to different hashes for me!
file.height = 100c-100
wrap = <div>|</div>
}

This is my GFX section in localconf.php:
$TYPO3_CONF_VARS["GFX"]["TTFdpi"] = '96';
$TYPO3_CONF_VARS['GFX']['im_path'] = '/usr/bin/';
$TYPO3_CONF_VARS['GFX']['im_version_5'] = 'gm';
$TYPO3_CONF_VARS['GFX']['noIconProc'] = '0';

The code sections changed with 6261.diff are actually called, I still get different hashes without applied patch (something like typo3temp/pics/a123456789b.png).

Please check if this bug is still reproducible for you in trunk or latest 4.2

Tested in 4.2.12 and 4.4-trunk without the patch.
Could not reproduce in both installations.

Like Jigal and Steffen on Core List I cannot reproduce this.
Fixed in current versions. TYPO3 4.0 no longer is supported and so won't be fixed (if that should still be buggy there).
