NOTE: If I change the PixelFormat8bppIndexed to PixelFormat24bppRGB it works fine. But with this, "c" is NULL.
Any suggestions?
Hello. I'm haveing an issue converting a bitmap to 256 colors. Really what I would like to do is grab a piece of the screen and convert it to a 256 color bitmap. The whole purpose is to display what a small image would look like on a device with a limited screen size and color depth.
a->GetHeight(),
PixelFormat8bppIndexed);

WCHAR* unicodeFileName = new WCHAR[currentFile.GetLength()+1];
MultiByteToWideChar(CP_ACP,0,ansiFileName,strlen(ansiFileName),unicodeFileName,currentFile.GetLength()+1);
Bitmap* tempbmp = new Bitmap(unicodeFileName);//error occur:error c2660 'new':function doesnot take 3 parameters
//but using like below can work well
Bitmap tempbmp(unicodeFileName);
What is wrong here??

I have it solved. Because MFC has operator new overload,so when you use Gdi+ in a mfc project ,you'd better comment the line #define new DEBUG_NEW .Of course if you build a release version,this is not a problem

Since I had problems using the new operator on gdi+ objects, I used:
#ifdef _DEBUG
#define SAVED_NEW new
#undef new
#endif
before allocating an Image object.
Now the allocation succeeded but it seems the operation itself didn't come out right, since looking at the allocated Image parameters the nativeImage is 0x00000000 and lastResult is InvalidParameter.
When I simply use ::new Bitmap( filename, FALSE) it comes out right but as mentioned before this object delete will fail.
Thanx in advance,
Asaf

Is there anybody who can help me?
Thanks in advance!
