Generating custom windowshapes within Rev

[Ian Wood]

Having played around quite a bit with custom windowshapes I finally  
got around to looking at Eric's recent tutorial which prompted me to  
try out an idea I had some time ago - the creation of custom  
windowshapes within the app itself.


Ingredients: Rev 2.7 and above - we're using the 'from object with  
full transparency' capability of the import snapshot command.

1. Make a graphic or group of graphics the shape that you want the  
window to be, applying corners with a radius, variable opacity etc. In  
this example, it's a rounded graphic called "windowshape". Original,  
hey?

2. Start with the following code and play around:

import snapshot from grc "windowshape"
put the id of the last img into tID
set the windowshape of this stack to tID

3. There is no step 3.

Obviously this is very bare bones, but a bit of extra tinkering gives  
us this:

import snapshot from grc "windowshape"
put the id of the last img into tID
set the windowshape of this stack to tID
put the propOldShape of this stack into tOldID
if tOldID is not empty then
	delete image id tOldID
end if
set the visible of the last img to false
set the propOldShape of this stack to tID

which automatically deletes the old temporary image.


Stick it all on a substack and we can have fully automated  
windowshapes, maybe even with the possibility of *resizable* custom  
shapes...
