[TYPO3-english] alpha background GIFBUILDER TYPO3 problem: Resolved!

[Francisco Cifuentes]

I've forgotten the typoscript:

plugin.tx_ourextension_pi1{

imageTransparency=fileadmin/transparentBackground.png

image_header=IMAGE
image_header{
posX=50
               posY=20
               transparentBackground = 1
               transparentColor = #893070
               backColor=#893070
  file = GIFBUILDER
       file{
     XY=260,20
   transparentColor = #893070
   transparentBackground = 1
   backColor=#893070
     10=TEXT
     10.tex=header
     10.text.case = upper
   10.text.align=center
   10.offset = 1,18
   10.fontFile = {$temp.corpcom.menuFont}
   10.fontColor = {$temp.corpcom.menuFontColor}
   10.niceText = 1
   10.fontSize = {$temp.corpcom.menuFontSize}

     11< .10
     12< .10
     15< .10


       }

}
image_image=IMAGE
image_image{
posX=0
               posY=50
               XY=260,180
               transparentBackground = 1
transparentColor = #893070
backColor=#893070
               file = GIFBUILDER
       file{
     backColor=#893070
     transparentBackground = 1
   transparentColor = #893070
     XY=260,180
     10 = IMAGE
     10.file.maxW=260



       }

}


}

>> Hi Francisco,
>>
>> IMHO it can not be achieved at all. I mean without changing the core.
>> The combine/composite command of ImageMagick is always called with
>> "+matte" option (see t3lib/class.stdgraphic.php around line 2549) which
>> disables the alpha channel of the output image.
>>
>> I have tried to set it to "-matte" and "-alpha On" but without any effect
>> :(
>>
>> But trying to run this in console:
>> Note: image1.png contains some graphic with transparent background,
>> image2.png is fully opaque
>>
>> composite -compose src-over -matte image2.png image1.png output.png
>>
>> behaves as intended = the resulting image is a composition of the two
>> images with transparent background...
