Superimpose without getting the picture background

[Michiel Spape]

Hi,
Yes, like in GIF the transparent colour is defined as the colour of one of the corners, you can set the colour which should be treated by E-Prime as transparent by changing backstyle to transparent and setting the source colour key. Or look in the help file:

Sourcecolorkey: The source color key allows the image to be transparent during presentation by specifying one color in the image as the transparent mask.  Pixels in the image that are the same color as the value set in SourceColorKey are not painted, which permits the image to appear transparent.  

Instead of photoshop, try the awesome programme MSPAINT (start>run>mspaint): fill the 'background' with white, set white as sourcecolourkey and the image to transparent.
Best,
Mich

Hi

What I want to do is to superimpose an arrow onto a picture. When
doing so the arrow image gets a black background eventhough the arrow
has been stripped from background in Photoshop an saved as .gif.

This way works in other programs (Authorware). Is it possible to get
an image superimposed to another image without E-Prime adding
background to the object?
