Question

I want to draw a shadow around a thumbnail in my software. It seems CreateHatchBrush can help but I do not know how to use it, can anyone provide me a sample in C++? Many thanks!

The easiest option would be to use GDI+ to do this. Here’s a quick and dirty shadow rendering sample:

void Render( HDC hdc ) {     Graphics gr( hdc );     Image image( L'sample.jpg' );     const int SHADOW_OFFSET = 7;      //     // draw shadow     //     SolidBrush shadow( Color( 190, 190, 190 ) );     Rect rc( 50, 50, image.GetWidth(), image.GetHeight() );     rc.Offset( SHADOW_OFFSET, SHADOW_OFFSET );     gr.FillRectangle( &shadow, rc );      //     // draw the image     //     gr.DrawImage( &image, 50, 50, image.GetWidth(), image.GetHeight() );      //     // draw a border     //     Pen border( Color( 0, 0, 0 ), 1 );     rc.Offset( -SHADOW_OFFSET, -SHADOW_OFFSET );     gr.DrawRectangle( &border, rc ); } 

Hope this helps!
