Re: Opacity Percentage?
The blendLevel seems a better solution in this case, but getting back to the handler posted at the URL below, could it not be simplified even further: on mouseUp put empty into aData put numToChar(128) into ch repeat for the number of chars in the alphaData of image 1 put ch after aData end repeat set the alphaData of image 1 of aData end mouseUp On Dec 4, 2004, at 4:46 PM, David Kwinter wrote: You'll need to use images and manipulate their alphadata.

Re: Opacity Percentage?
Dear Rick I experimented with this problem and it seems to have a really straightforward solution (unless I misunderstand the problem) ... I created empty image areas on a card and then used the fill tool (in the graphics tools at the bottom of the toolbox) to fill them with colors (e.g. red, green blue). If I then set the blend property to on by checking the box on the property inspector for each image area, I could manually set their opacity using the slider on the property inspector, or in a script, by using a command of the form: set the blendLevel of image myImage to 50 This seems to have the desired effect for creating colored semi-transparent filters. I guess the colors are innacurate unless you do some more fancy screen calibration - but is this what you were trying to achieve? Best Gordon --- Frank D.

Gordon Gordon, You must have missed my last post. That was the approach I ended up using, and it works great. My initial problem was that the Rev documentation didn't show me a cross reference when I was searching it for opacity. Once I understood that I needed to use Blendlevel everything fell into place.

Regards, Scott Rossi The blendLevel setting works perfectly! I hooked it up to a slider bar so I can watch the color changes in real time. Four lines of code did it all! I still marvel at the incredible power of Rev! Many thanks to David, Dar, Scott, and Chipp for such quick answers!

Re: Opacity Percentage?
If all you want to do is change the opacity, then just create a 10x10 pixel color square image (.png should do), set it the size you wish, set the lockloc of it to true (so it won't resize back to 10x10) and then do like Dar suggests: set the blendLevel of img blue10x10.png to 50 (sets it to 50% transparent) -Chipp Rick Harrison wrote: I wanted to create a bunch of different color filters and to be able to change the opacity by percentages. ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
