GEORGE : tv_imageIsEmpty layerID iPosition

[Mads Juul]

I would like a George command to quickly tell if an image is empty
Something like

Code: Select all

GEORGE : tv_imageIsEmpty layerID iPosition
RETURN bool 
1 if image(frame) is empty. 0 if something is drawn on the image

I know there is ways to do this with George for instance with tv_layercompareimage
But I would prefer a simpler solution that didn't inklude making new empty instances or layers

I would prefer something like that ( "0" for "Empty" seems to me more intuitive) :

Code: Select all

GEORGE : tv_ImageContents layerID iPosition
RETURN bool 
- 0 if image(frame) is empty, 
- 1 if something is drawn on the image //pixel(s) with alpha > 0

I agree.

A quick way is to capture the complete frame into a cutbrush, optimize the cutbrush and check its dimensions... of course you would probably want to somehow temporarily store the current cutbrush or animbrush image so you could restore it after the test.

I know but it is slow . I also have a different feature request for optaining the dimension of an image here

In the thread I also briefly discusses the problems involving using the cutbrush method.

Forgot dat. Having a George command for dimensions of a cutbrush and another that tests for a blank frame would be useful, especially inside a script that does other things as well.

so +1.
