[TYPO3-english] GIFBUILDER watermark poor quality

[Jan Bednarik]

Hi folks,

I'm adding a watermark to images using GIFBUILDER but the output quality 
is very poor. It looks like the image is converted into 256b GIF 
(although it's still JPG). The config is following:

image = IMG_RESOURCE
image {
   file = GIFBUILDER
   file {
     XY = [20.w],[20.h]
     format = jpg
     quality = 100

     20 = IMAGE
     20.file.import = uploads/tx_pxbgalerie/
     20.file.import.current = 1

     30 = IMAGE
     30.file = fileadmin/templates/pixelbox/img/vodoznak.png
     30.mask = fileadmin/templates/pixelbox/img/maska.png
     30.offset = [20.w]-124,[20.h]-71

   }
}

Any ideas how to improve the output?

Thanks

Jan
