DIB to Bitmap

Hi all,

I have the folowing structure:

static BITMAPINFOHEADER bmpInfo;
static BYTE *pVideoBuffer;

who can I get the content of the buffer and create a TbitMap ??

Thanks for all

Use the StretchDIBits() API function to draw the DIB to the canvas of
your TBitmap. Something like (untested):

StretchDIBits(MyBitmap->Canvas->Handle,
destX, destY,
destWidth, destHeight,
srcX, srcY,
srcWidth, srcHeight,
yourBits, yourInfoHeader,
DIB_RGB_COLORS, SRCCOPY);

Good luck!

Re:DIB to Bitmap

Thank you very much Yoto

Now I have another problem.. How to Send it back?

How to send a bitmap image to fill the folowing structs?

static BITMAPINFOHEADER bmpInfo;
static BYTE *pVideoBuffer;

Re:DIB to Bitmap

The DIB should be checked to see if it is a pallette
based DIB, and if the destination DC needs a pallette,
it will require some palette handeling code.

Re:DIB to Bitmap

// see DIBSECTION in "C:\Program Files\Common Files\Borland Shared\MSHelp\win32sdk.hlp"

DIBSECTION JDIBSECT ;
ABmp->HandleType = ??DIB ;

int dibsize = sizeof(DIBSECTION) ;
int Len = ::GetObject (ABmp->Handle, dibsize , &JDIBSECT) ;
if(dibsize != Len) throw Exception ("GetObject-DIBSECTION" ) ;
JWidthBytes = (int) (JDIBSECT.dsBm.bmWidthBytes) ; // mult_of_4 "width of scanline"
JBits = (BYTE*)(JDIBSECT.dsBm.bmBits) ; // image data
JSizeImage = (int) (JDIBSECT.dsBmih.biSizeImage) ;
