[TYPO3-english] GIFBUILDER duplicates images

[Alexander Dorn]

Hello,

I got a problem with a TYPO3(v.6.1) installation.

I am using GIFBUILDER to render a watermark on my images. Every time the page is reloaded the GIFBUILDER re-renders every image. where the mask is used 

The folder typo3temp/GB grew to over 3GB on my developement system.

Here are the file names generated. The hash of the mask is calculated differently, so the image is rendererd again.

csm_E-3R_Bad_04_764b6ddafa_mask_c1a301ebdf.jpg


This is the TS use:

lib.watermark600 = IMAGE
lib.watermark600 {
    file = GIFBUILDER
    file {
        XY = 600,400
        format = jpg

        quality = 95

        20 = IMAGE
        20.file = EXT:property_manager/Resources/Public/img/maske.png
        20.offset = 25,25
        15 = IMAGE
        15.file.import.current = 1
        15.file.width = 600c
        15.file.height = 400c

    }
}

The Typoscript is rendered in a FLUID-template via:
<f:cObject typoscriptObjectPath="lib.watermark600" data="uploads/tx_propertymanager/{firstImage.image}" />

Any help is appreciated.

Regards Alexander
