Hi!

I am failed to use DisplayTextObject() on an alphachannel after SelectAlphaChannel(). However I can use drawing functions successfully for this purpose.

I'd like to make transparent brushes with 0% transparent text on it. Is it possible somehow?

In German I would answer "Jein", which is a mixture of "Ja" (yes) and "Nein" (no).

The problem is that SelectAlphaChannel() currently always draws to the alpha channel with the intensity specified with SetAlphaIntensity(). Thus, you cannot copy any arbitrary alpha channel data from a text object to the alpha channel of a brush.

What you can do, however, is to create a full brush copy of a text object by using GetBrushLink(). GetBrushLink() in Hollywood 2.0 does NOT create a link as the very name suggests, but creates a full copy of the source object. So you could convert your text object to a brush including alpha channel.

In Hollywood 2.5 which will be released soon (hint, hint), there are two new functions which are more helpful:

Code: Select all

; the special value #VANILLACOPY will do a 1:1 copy of alpha channel
; data which is exactly what you want
SetAlphaIntensity(#VANILLACOPY)

; converts any object to a brush
ConvertToBrush()
