Hello,

What commands should I be using If I want to cover an image opened in my ole control with a rectangle? For security reasons, certain users should not be able to see some images - but I still want to display them - just basically hide or cover them with rectangle.

I use Leadtools 14.5 and my ole is Lead Main Control 14.0.

Thanks a lot in advance for any hints,

Srechko

Hello,

You can try to use LEAD1.DrawRectangle method to draw a rectangle on the screen or on the bitmap. The DrawPersistence property determines whether the object is drawn on the screen or the bitmap.

For example, the following code shows how to draw a red rectangle on the bitmap:
--------------------------
LEAD1.Load "D:\testing\Ann.jpg", 0, 0, 1
LEAD1.DrawFillColor = vbRed
LEAD1.DrawMode = DRAWMODE_COPY_PEN
LEAD1.DrawFillStyle = DRAWFILLSTYLE_SOLID
LEAD1.DrawPersistence = True 'On the window, not the bitmap

LEAD1.DrawRectangle 0, 0, LEAD1.BitmapWidth, LEAD1.BitmapHeight
--------------------------

Thanks,
