ImagePush ImagePop bug in TVP 10
Posted: 07 Nov 2012, 09:44
Something strange when an image is pushed onto the image stack, then popped off the image stack, which only happens in TVP release 10...
Looking at the attached image below we see four ABC drawings.
Images 1 and 2 are TVP 9.5 while images 3 and 4 are TVP 10.0.11.
For all drawings, the tool is a PenBrush set to size 9, power 75% opacity 75%.
Here's what I did in image 1 and 2 using TVP 9.5:
In image 1, I drew the letters and used the Push Image button to put it onto the image stack.
I then cleared the screen.
I then used the Pop Image button to restore the original image.
Finally for image 2, I draw transparent lines over ABC and crossed out TVP 9.5.
You can see the transparent strokes in image 2 work as expected with the original image letters showing through the transparent overdrawn strokes.
When I did the same thing in Image 3 and 4 using TVP 10.0.11, the result of drawing the transparent strokes over the ImagePop letters has a strange, stair-steppy edge of gray around the new strokes... no transparency. Further more, if I try to erase using the right-mouse-button (barrel switch plus tip switch) it just draws more lines with the gray area around the eraser strokes. Obviously, something isn't working right in TVP 10 when the Pushed Image is ImagePopped onto the cleared frame.
Note this happens in TVP 10 whether I use a George script (tv_ImagePush, tv_clear, and ImagePop) OR when I use the Push Image button, the clear frame button and then the Pop Image button for the same result.
Wonder what changed between TVP 9.5 and TVP 10 to cause this drawing malfunction?
Can anyone confirm this problem in TVP 10?
