TIEBitmap.CopyFromDIB

Declaration

procedure CopyFromDIB(Source: THandle); overload;
procedure CopyFromDIB(BitmapInfo: pointer; Pixels: pointer = nil); overload;

Description

Copies from the specified DIB handle.
The second overload copies from a DIB composed by a BitmapInfo structure and pixels buffer pointer.
When Pixels is null, pixels are supposed to stay just after BitmapInfo structure.

Note: if ParamsEnabled = True, then the DPI is returned in Params.DpiX and Params.DpiY

Example

IEBmp :=TIEBitmap.Create();
IEBmp.ParamsEnabled := true;   // So we can get the DPI
IEBmp.CopyFromDIB( HDib );     // Copy from HDIB passed by scanner
lblDPI.caption := IntToStr( IEBmp.Params.DpiX );
ImageEnView1.IEBitmap.assign( IEBmp );
IEBmp.Free;
