Fotomix - Tutorial 4: Transparent background

The figure below is actually a HTML table with a cell which has a sort of paper image background.
The image of the flower and butterfly is being displayed on top of the paper background.

To remove the background of the flower/butterfly image, you would need to make that background transparent, and that's what you use the transparent background option in FotoMix for.

On the Background Page we select Transparent Background and a size a bit larger than the flower/butterfly image.
On the Foreground Page we import the flower/butterfly image and erase the background as shown below.

On the composition page, we simply fade a bit of the flower stem. and the final image which we save is shown below.

Note that most browsers and image programs are only able to handle transparency within GIF and PNG files.
GIF files can only hold images where the transparency is either on or off. PNG files can hold images with grades of transparency. Therefor, GIF files often result in images shown with ragged edges. PNG files however, can have nice anti-aliased edges.
The illustration below, shows the HTML table cell with paper background and a PNG transparent flower/butterfly image on top.
