BitmapFromDib (ImageKit Control/ Custom Method)

This method converts a Device Dependent Bitmap to a Device Independent Bitmap

Parameters

Return Value

Returns True if successful, otherwise returns False.

Explanation

The DibFromBitmap method converts a Device Dependent Bitmap to a Device Independent Bitmap. If successful, the image handle is set in the LayerNo property (ImageHandle property or Layer(LayerNo).ImageHandle property).

This method can be used to retrieve an image from TBitmap.

Note: The argument hBm is not freed after executing this method.

In C++Builder:

      //Set a raster image in TBitmap

      Graphics::TBitmap *bm = new Graphics::TBitmap();
     try
     {
          bm->LoadFromFile("C:\\Bmp\\001.bmp");
          // Some image processing code
          VImageKit1->LayerNo = -1;
          VImageKit1->DibFromBitmap(bm->Handle, bm->Palette);
          // Some image processing code
     }
     __finally
     {
          delete bm;
     }

In Delphi:

      {Set a raster image in TBitmap}

      var
          Bitmap1: TBitmap;
     begin
          Bitmap1 := TBitmap.Create;
          try
               Bitmap1.LoadFromFile('C:\Bmp\001.bmp');
               {Some image processing code}
               VImageKit1.LayerNo := -1;
               VImageKit1.DibFromBitmap(Bitmap1.Handle, Bitmap1.Palette);
               {Some image processing code}
          finally
               Bitmap1.Free;
          end;
     end;
