Depends on the shape of the content that will still be visible.

If you've got rectangular content like boxes or images you can simply set
backgroundColor and transparentColor to the same value.

If there are rounded or sloped shapes (i.e. letters of a font you are using
in GIFBUILDER) you have to disable antialiasing and nicetext to get sharp
edges, but this will lead to a very ugly look and therefor I would not
recommend it.

In these cases you could use the workaround described in the thread you
already found and use the background image as a GIFBUILDER background. With
some cropping you will get the area that fits the position of your image and
with some masking you can still make it transparent but leave the
anitaliased borders visible.
