Hi Mario,

Here's a simple way:

Code: Select all

on mouseUp
     lock screen
     choose select tool
     drag from the topleft of img 1 to the loc of img 1
     cut
     choose browse tool
     unlock screen
end mouseUp
Best,

Hi Mario,

Of course it runs. Probably, you mean that it doesn't do what you want.

Why exactly do you want to delete an area of an image that's covered by a button?

Best,

Mark

..some btns are transparent... and only the img over them is visible...
by clicking on a different btn ... it should be possible to erase a part of the img...

Dear Mario,

Why? Maybe there's a different way to do it, but I need to know why.

Best regards,

Mark

Dear Mark
some times the procedure you told me runs ... and the corrispondent part of the img is erased...
some times it doesn't happen nothing...
perhapse it depends from the img data... i use imgs taken from web..
i'm studying it..
best,
mario

Hi Mark
I' thinking also that it may be impossible to drag ,within an image, if the point from which the drag action begins is not within the img itself....
