Lets you setup FX processing to the current frame, copies it into the Spare Buffer, restores the current frame and sets the drawing tool's mode to Merge. This lets you selectively modify the current frame by simply drawing... Each stroke on the current fame reveals FX imagery from the Spare Buffer.
To use:
1. Setup the FX Stack window with your effect. DO NOT APPLY IT TO THE FRAME.
2. Click the FXBrush button. You won't see any change, but the FX process has been applied to the frame which was then copied into the Spare Buffer.
3. Draw anywhere you want on the frame image and the strokes will modify it using the FX processed Spare Buffer image.
4. Clicking the FXBrush button at any time will update the Spare Buffer, after re-applying the FX process to the current image.
5. When you are done "merging", set the draw-Mode back to Color to revert again to normal drawing functionality.
TWO CAUTIONS:
1. The Merge draw-mode isn't available with the custombrush tool, so a warning message will appear. Stop using custombrush and select some other drawing tool (penbrush, airbrush, filled shape, etc.) and press the FXBrush button again.
2. If you have no FX loaded in the Stack window, you will get an "FX Stack" error message when you press the FXBrush button.
ViewBuffer Button
Lets you temporarily view the contents of the Frame Buffer and return to the current frame.
To use:
Clicking the ViewBuffer Button swaps the current frame with the Spare Buffer so you can see the image you will be merging. Click OK in the pop-up warning window, to swap the Buffer image with the current frame and proceed with merge-drawing.
