hi,
i have an application which is a kind of a drawing application. i have a background map(CDib) on which i want to draw some polygons. these polygons are getting filled by an hatch brush in a transparent mode, i.e., the background can still be seen (i used FillRgn() to fill the polygons).  the problem is that while printing the whole thing, the transparent mode dissapears, the polygon covers all its area and the backgrounf under it cannot be seen anymore.
i'll be thankful for anyhelp.

You might be relying on default brushes while drawing polygons. Try selecting a brush with appropriate mode before drawing the polygons.

I assume a print previoew shows things correctly.

Many printers have problems with transparency etc.  For example, I have one printer that, if you set the fill hatch colour to white, will print the fill balck.  Other printers will print transparently when on screen things are obscured.

I suggets you either try another printer, and / or check that you have the latest printer driver for that printer.

after dealing with it for quiet a long time i guess RONSLOW is right. it all depends on the printer and/or its driver.
