dxFillBitmapInfoHeader(TBitmapInfoHeader,Integer,Integer,WordBool) Method

Returns the header information of a specified bitmap object.

Declaration

procedure dxFillBitmapInfoHeader(out AHeader: TBitmapInfoHeader; AWidth: Integer; AHeight: Integer; ATopDownDIB: WordBool);

Parameters

Name	Type
AHeader	TBitmapInfoHeader
AWidth	Integer
AHeight	Integer
ATopDownDIB	WordBool

Remarks

This method obtains the header information from the bitmap object passed as the ABitmap parameter and returns this information as the AHeader parameter. The second overloaded variant allows you to obtain the header information for a bitmap with dimensions passed as the AWidth and AHeight parameters.

Pass True as the ATopDownDIB parameter to specify if the bitmap object is a top-down DIB. Otherwise, it is considered a bottom-up DIB.

Note

Both the variants set the biPlanes, biBitCount, and biCompression fields of the returned header object to 1, 32, and BI_RGB, respectively.
