Handle of a DrawDib DC.
Handle of a DC for drawing. This parameter is optional.
Width and height, in MM_TEXT client units, of the destination rectangle.
Address of a BITMAPINFOHEADER
structure containing the image format. The color table for the DIB follows
the image format and the biHeight
member must be a positive value.
Width and height, in pixels, of the source rectangle.
Applicable flags for the function. The following values are defined:
Allows palette animation. If this value is present, DrawDib reserves as many
entries as possible by setting PC_RESERVED in the palPalEntry
members of the LOGPALETTE
structure, and the palette can be animated by using the DrawDibChangePalette
function. If your application uses the DrawDibBegin
function with the DrawDibDraw
function, set this value with DrawDibBegin
rather than DrawDibDraw
Realizes the palette used for drawing as a background task, leaving the
current palette used for the display unchanged. (This value is mutually exclusive of
Causes DrawDib to try to use an off-screen buffer so DDF_UPDATE can be used.
This disables decompression and drawing directly to the screen. If DrawDib is
unable to create an off-screen buffer, it will decompress or draw directly to the
screen. For more information, see the DDF_UPDATE and DDF_DONTDRAW values
described for DrawDibDraw
Current image is not drawn, but is decompressed. DDF_UPDATE can be used later
to draw the image. This flag supercedes the DDF_PREROLL flag.
Always dithers the DIB to a standard palette regardless of the palette of the
DIB. If your application uses DrawDibBegin
, set this value with DrawDibBegin
rather than DrawDibDraw
Draws the image by using GDI. Prohibits DrawDib functions from decompressing,
stretching, or dithering the image. This strips DrawDib of capabilities that
differentiate it from the StretchDIBits
Use the current drawing parameters for DrawDibDraw
. Use this value only if lpbi
, and dySrc
have not changed since using DrawDibDraw
. This flag supercedes the DDF_SAME_DIB and DDF_SAME_SIZE flags.
Use the current DC handle and the palette currently associated with the DC.
Last buffered bitmap needs to be redrawn. If drawing fails with this value, a
buffered image is not available and a new image needs to be specified before
the display can be updated.
Returns TRUE if successful or FALSE otherwise.
This function prepares to draw a DIB specified by lpbi
to the DC. The image is stretched to the size specified by dxDest
. If dxDest
are set to
1, the DIB is drawn to a 1:1 scale without stretching.
You can update the flags of a DrawDib DC by reissuing DrawDibBegin
, specifying the new flags, and changing at least one of the following
, or dySrc
If the parameters of DrawDibBegin
have not changed, subsequent calls to the function have no effect.
