CreateDIBPatternBrush info  Overview  Group

The CreateDIBPatternBrush function creates a logical brush that has the pattern specified by the specified device-independent bitmap (DIB). The brush can subsequently be selected into any device context that is associated with a device that supports raster operations.

This function is provided only for compatibility with applications written for versions of Windows earlier than 3.0. For Win32-based applications, use the CreateDIBPatternBrushPt function.

HBRUSH CreateDIBPatternBrush(

    HGLOBAL hglbDIBPacked,

// handle to device-independent bitmap

    UINT fuColorSpec 

// color table data

   );

Parameters

hglbDIBPacked
Identifies a global memory object containing a packed DIB, which consists of a BITMAPINFO structure immediately followed by an array of bytes defining the pixels of the bitmap.

Windows 95: Creating brushes from bitmaps or DIBs larger than 8x8 pixels is not supported. If a larger bitmap is specified, only a portion of the bitmap is used.

fuColorSpec
Specifies whether the bmiColors member of the BITMAPINFO structure is initialized and, if so, whether this member contains explicit red, green, blue (RGB) values or indices into a logical palette. The fuColorSpec parameter must be one of the following values:

Value

Meaning

DIB_PAL_COLORS

A color table is provided and consists of an array of 16-bit indices into the logical palette of the device context into which the brush is to be selected.

DIB_RGB_COLORS

A color table is provided and contains literal RGB values.

Return Values

If the function succeeds, the return value identifies a logical brush.

If the function fails, the return value is NULL. To get extended error information, call GetLastError.

Remarks

When an application selects a two-color DIB pattern brush into a monochrome device context, Windows does not acknowledge the colors specified in the DIB; instead, it displays the pattern brush using the current background and foreground colors of the device context. Pixels mapped to the first color of the DIB (offset 0 in the DIB color table) are displayed using the foreground color; pixels mapped to the second color (offset 1 in the color table) are displayed using the background color.

When you no longer need the brush, call the DeleteObject function to delete it.
