Performing a Transparent Sweep Within Paintbrush

• Microsoft Windows operating system versions 3.0, 3.0a

SUMMARY

Within the Windows version 3.0 Paintbrush program, you can only sweep a cutout transparently if the selected background color is the same background color as the image to be swept.

MORE INFORMATION

When doing a transparent sweep, the selected background color is not swept, so the underlying colors show through. If the background color of the selected image is not the same as the selected background color, the background color of the image is swept and draws over itself.

Steps to Reproduce Problem

1. Start Paintbrush.

2. Using the Line tool, split the screen from top to bottom, making sure that the split is complete.

3. Using the Paint Roller tool, make the right half of the screen red.

4. Draw a black, empty square in the white half of the screen. The square image is just an example. Any image can be used to see the effects.

5. Choose the Pick tool and outline the square image.

6. Hold the CTRL key down and drag the image with the left mouse button that starts a transparent sweep and then the right mouse button that starts an opaque sweep. At this point, proceed to cross in and out of the red half of the screen.

7. Change the background color and repeat step 6.
