TYPO3 Core

I try to reproduce the example from:

http://wiki.typo3.org/GIFBUILDER

in STRATO hosted WEB server with;

typo3 Vers: 4.7.7
ImageMagick 6.2.1-2

localconf.oho is attached.

TS:
temp.headpics = COA
temp.headpics {
10 = IMAGE
10 {
file = GIFBUILDER
file {
XY = 800,600
format = jpg
quality = 70
10 = IMAGE
10.file = fileadmin/yag/watermark/Backimage.jpg

15 = IMAGE
        15.offset = 40,40
        15.file = fileadmin/yag/watermark/typo3.png
        15.mask = fileadmin/yag/watermark/typo3_mask_i.png

}
  }
}

page.10.subparts.INHALT < temp.headpics

The jpg and the png's are downloaded from http://wiki.typo3.org/GIFBUILDER

the result in not realy satified (see result.jpg)

I made a test on a local typo3 4.7.7 installation from introduction package
with GrafikMagick settings -> every thing works fine

Next tested with ImageMagick 6.8.1-9 installation on the local web server.
Again the result ist not realy satisfied (see result2.jpg)

After a little bit of googling for the error I found a hint in Bug #37060
an tried this setting on both systems.
Not really better:

STRATO Server: result3.jpg
local WEB Server: resul4.jpg
