Apply antialiasing to scaled button icons

Please see the attached Sample Project. I also included a screen shot showing how it appears on my computer. The other thing I notices was that even though I am loading the same image, the graphic is smaller in the Wizard Button than in the cxButton.

Please note that the graphic was purchased and thus copyrighted. Included several different sizes in case you need to test with them.

Thanks in advance for your assistance.

Thanks, Luke. I see that the image is correctly loaded, but in the Wizard Control's button it is automatically resized to better fit the button's size. I mean, you can set the dxWizardControl.Buttons.Common.Height property to 36 to make this image look better (just like in the TcxButton control). Moreover, I see that the focus rectangle overlaps the image in the TcxButton button. So, you can also increase the TcxButton.Height property to make the focused button look better.
I have found that this image is drawn in the TdxWizardControlButtonViewInfo.DrawContent method of the dxCustomWizardControl.pas unit, so Wizard Control uses different painting routines than the TcxButton button. If you modify this method in the following manner, even resized images in your Wizard buttons should be drawn much better:

[Delphi]
procedure TdxWizardControlButtonViewInfo.DrawContent(ACanvas: TcxCanvas);  
const  
  EnabledImageDrawModeMap: array [Boolean] of TcxImageDrawMode = (idmNormal, idmDisabled);  
var  
  AOffset: TPoint;  
  AGlyphBitmap: TBitmap;  
begin  
  if not FadingHelper.DrawImage(ACanvas.Handle, Bounds) then  
    DrawButtonBackground(ACanvas, Bounds, State);  
  AOffset := Painter.GetButtonOffset(State);  
  
  if not cxRectIsEmpty(GlyphRect) then  
  begin  
    if not Button.Glyph.Empty then  
      AGlyphBitmap := Button.Glyph.GetAsBitmap  
    else  
      AGlyphBitmap := nil;  
    try  
      cxDrawImage(ACanvas.Handle, cxRectOffset(GlyphRect, AOffset),  
        cxRectOffset(GlyphRect, AOffset), AGlyphBitmap, WizardControl.Buttons.Images,  
        Button.ImageIndex, EnabledImageDrawModeMap[State = cxbsDisabled], True);  
    finally  
      AGlyphBitmap.Free;  
    end;  
  end;  
  
  ACanvas.SaveState;  
  try  
    ACanvas.Font := Font;  
    ACanvas.Font.Color := Painter.GetButtonTextColor(State);  
    if not cxRectIsEmpty(CaptionRect) then  
    begin  
      cxDrawText(ACanvas, Button.Caption, cxRectOffset(CaptionRect, AOffset),  
        DT_VCENTER or DT_SINGLELINE or DT_CENTER);  
    end;  
    if IsFocused then  
      ACanvas.DrawFocusRect(Painter.GetButtonFocusRect(ACanvas, Bounds));  
  finally  
    ACanvas.RestoreState;  
  end;  
end;

With this modification, you will be able to keep the 30 value for the dxWizardControl.Buttons.Common.Height property. I think that we can modify our source code in future builds to make this modified drawing routine default for our Wizard buttons. Please let me know your opinion.

Thank you for your observations. For now, I will just adjust the button height rather than modify the dxCustomWizardControl.pas unit.

Personally, I would think that the wizard would draw the buttons the same way as cxButton does.

You may close this issue and thank you again for your assistance.

Go ahead and make the content of this ticket visible. You do need to remove the attachments as they include graphics that I purchased.

Thanks!
