kowal	Posted - Aug 30 2023 : 13:10:29 Hi, I'd like to do some operations on the new created IEBitmap i.e. draw some symbols to use them later in my application. But I can not access the IEBitmap canvas. here is the snippet of my code procedure Tfienv.ietest1Click(Sender: TObject); var iebmp: tiebitmap; begin iebmp := tieBitmap.Create; // I got av error here - the Canvas property is nil iebmp.Canvas.Brush.Color := clBlack; iebmp.Canvas.Pen.Color := clWhite; end; How can I create an image using TIEBitmap? regards S. Kowalski

xequte	Posted - Aug 30 2023 : 18:43:48 Hi Canvas requires a valid VclBitmap, so call iebmp.VclBitmap after creating to initialize it (this is automatic in the next update). https://www.imageen.com/help/TIEBitmap.VclBitmap.html However, rather than Canvas, you are better to use the GDI+ canvas instead: https://www.imageen.com/help/TIEBitmap.IECanvas.html It is much more powerful: https://www.imageen.com/help/TIECanvas.html Nigel Xequte Software www.imageen.com
