A Different way to hilight a Black and White scan

[jclements]

If any of you ever import black and white scans of CAD drawings, here is a way to highlite specific areas of the image. I don't think it can be done using existing transparency effects.


Import the scan. Scale and/or crop it to the required size for print output or exporting. Make a bitmap copy.

Assign the bitmap copy of the scan as a Background (via the BitMap Gallery).

Click on the bitmap object with the Fill tool, then drag a color from the color-line onto the center fill-handle; this will change the color of the blacklines.

Now draw a "highlighting" shape. Give it a glow shadow. With the shape still selected move it behind the bitmap and shift-select the bitmap, and apply a clipview. The result is similar to a Stained Glass transparency, but what would normally be retained as black is now a different hue.

If you want to change the position of the Hilight object, click on the upperleft-keyhole icon of the clipview and USE THE ARROW KEYS TO NUDGE THE CLIPPING OBJECT to a new position.

Good use of clipview there - useful
