I'm using owner drawing on a button, catching the WM_DRAWITEM message and rendering various bitmaps/text to the hdc. My problem is that I am trying to use the ANTIALIASED_QUALITY flag on a font which fails to draw the text antialised. <br />
<br />
I have the following:<br />
<br />
LPDRAWITEMSTRUCT lpdis = (DRAWITEMSTRUCT*)lParam;<br />
HDC hMemDC = CreateCompatibleDC(lpdis-&gt;<wbr />hDC);<br />
int i = GetDeviceCaps(hBmpDC,BITSP<wbr />IXEL);<br />
<br />
GetDeviceCaps returns 16; does this indicate that my HDC is only 16bit? Perhaps this is why the antialising isn't working, as I understand this needs to be at least 24bit? How can I accomplish this?<br />
<br />
Appreciate any suggestions.

Ownerdrawn buttons in only 16bit?

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
