Transparent Bitmap

[cpaige]

Does any body have any source code to display a Transparent Bitmap. One restriction, it can be in C++ ,but no MFC!!!!<br><br>Making a lean and mean program and have no interest in extra stuff being traported with the EXE. <p>Clayton T.

Dear Clayton,<br><br>Nigel Thompson has code available on MSDN for drawing Bitmaps using a transparent pixel value. He also authored a great book for performing animation in windows applications, before DirectX.<br><br>Good luck<br>-pete

Thank You!<br>&nbsp;Do you know by any chance what the name of the article is? <br> <p>Clayton T. Paige<br><a href=mailto:cpaige@home.com>cpaige@home.com</a><br><a href=

Dear Clayton,<br><br>Well that would actually be considered an outdated method so maybe you should just start with OpenGL here:<br><br><A HREF="

should get you started researching the issue of rendering images. You will be reading for some time I think when you start to discover paletts, double buffering and more.<br><br>Good luck<br>-pete

I'm not real intersted in using OpneGL or any graphics engines.&nbsp;&nbsp;I was hoping to use just the windows GDI.&nbsp;&nbsp;Speed isn't really important.&nbsp;&nbsp;Just small code with as much portablity as posible. So, if you have&nbsp;&nbsp;a fresh install of Win95a or WIn98se it will still run with out any other files other then the EXE.&nbsp;&nbsp; <p>Clayton T.

Clayton,<br><br>&gt; I was hoping to use just the windows GDI.<br><br>Then you just want to use BitBlt(), StretchBlt() or DIB_BitBlt() which ever works for you and you will have to setup a DRAWMODE structure to provide the transparency information, etc. Also you must take into account any Palette issues depending on your bitmap(s).<br><br>If you've never done any of this before you will likely need to do some research.<br><br>&gt; Does any body have any source code to display a Transparent Bitmap<br><br>No it's not exactly the sort of solution that can be accomplished in a dozen lines of code.<br><br>Good luck<br>-pete<br><br><br>

Win32 API &quot;BitBlt&quot; will do it.&nbsp;&nbsp;You just need to create a negative mask of your image and it will blit the information in rotation.<br><br>Read up on Bitblt.<br><br>Brian
