Have a look at these 4 expressions: SnapshotRedAt(x, y), SnapshotGreenAt(x, y), SnapshotBlueAt(x, y), SnapshotAlphaAt(x, y). Those expressions combined pick the colour of an exact point.
I saw them but they took info from whole frame/layers.
Can I take snapshot of the frame just for certain objects or layers?
If not, those expressions will get wrong color.
For example lets take scene: color sprites with 50% opacity on top of ground image. SnapshotRedAt(x, y) will count RGB of the ground too but only RGB of sprites needed.
Since I could not sample color directly from layer my idea was to use canvas as way to draw color info there and sample it from there somehow.
Paste just the objects you want into the canvas, take the snapshot, then sample the pixels. e.g.
-> Paste object Sprite with effects
-> Save snapshot
-> Wait for previous actions to complete
-> Log in console: DrawingCanvas.SnapshotRedAt(0, 0) & " " & DrawingCanvas.SnapshotGreenAt(0, 0) & " " & DrawingCanvas.SnapshotBlueAt(0, 0) & " " & DrawingCanvas.SnapshotAlphaAt(0, 0)
Oh my, NOW I get it!
Somehow I thought of 'snapshot canvas' from System actions. Now I see that Drawing Canvas have its own snapshot that does everything I asked for.
Thank you for your patience!
