You probably know PNG This file format supports an "alpha" channel matte called in ImageMagick which is another channel besides RGB and defines "how transparent" each pixel is. The results are not very nice. But there is the possibility to use ImageMagick for this task. In TYPO3 this is not done with a single image containing RGB and alpha channel to overlay but rather two separate images: The RGB image itself overlay image and 8-bit grayscale image defining the alpha-channel Mask image.

Here "backimage. For example: Then you will need an image to overlay over the original. It should have no alpha channel. And as last thing you will need the transparency mask. It depends on your Image Magick version and setting wether the black or the white areas will be completely transparent or not.

Here is an example of an image mask and inversion of it: And here the inversed: The resulting masked image will look like: You can create the mask from a colored file using the ImageMagick command "-colorspace GRAY". You can negate it by adding the command "-negate". But this tasks can also be done with every better image manipulation tool Gimp i.

How to create a mask from an Alpha-Layer PNG If your designer supplies you with a Photoshop file with transparency mask or a PNG you will have to extract the alpha channel information out of the image. Click on the thumb of the colored image to select working on the image and not on the layer mask. Move the layer tothe correct position so it is below the just filled regions. Now you should have a black white image containing the mask from the alpha layer.

Tested with IM v6. Creating semi-transparent Boxes with transparent Text Using the GIFBUILDER you can also create images from photos and insert a box which could probably be semi-transparent so the background shines through, And insert some "transparent" letters which will let the background image shine through into the box. Then you could retrieve the background image from the media field for example.

The base image is the same as above. The transparency of the text. This is easily possible using one of the following two TypoScript variants. Variant 1 Here a background image gets used. The background image shadow.
