Create bitmap from info and data

[tbeu]

I need to know how to create a bitmap from bitmap info and bits, i.e.

Code: Select all

[in] BITMAPINFO *info
[in] unsigned char *bits
[out] HBITMAP hbmp

Any idea how to do this?
Thanks!

CreateDIBSection

Code: Select all

HBITMAP CreateDIBSection(
  HDC hdc,                 // handle to DC
  CONST BITMAPINFO *pbmi,  // bitmap data
  UINT iUsage,             // data type indicator
  VOID **ppvBits,          // bit values
  HANDLE hSection,         // handle to file mapping object
  DWORD dwOffset           // offset to bitmap bit values
);

You can use the returned pointer *ppvBits to copy the bits into the Device Independent Bitmap.

Code: Select all

HBITMAP GetBmp(BITMAPINFO *info, unsigned char *bits)
{
	HDC dc = CreateCompatibleDC(NULL);
	unsigned char * bits2;
	HBITMAP hbmp = CreateDIBSection(dc, info, DIB_RGB_COLORS, (void **) &bits, NULL, 0);
	if (hbmp) memcpy(bits2, bits, info->bmiHeader.biSizeImage);
	DeleteDC(dc);
	return hbmp;
