Sorry for all the questions but i'm new to this digital paint stuff and am trying to get some basics down. I have a simple application in C# (Lead Tools 14.5 Raster Pro) that loads an image from file into a RasterView control and I am trying to use the digital paint class to draw a rectangle onto the image. I've searched the Help files and have not had any luck finding anything that does this in C#. Can someone provide me with some direction on howto draw a basic opaque rectangle using these controls.

thanks,

jp

You can use the GDI Plus Graphics instead of Digital Paint to create a basic rectangle  in your application.

For more information and code sample, please refer to the "IRasterImage.CreateGdiPlusGraphics Method" topic in LEADTOOLS .NET Help file.

I am not using the .net package, just the standard Lead Tools Raster Pro 14.5.

There is a way to create a basic rectangle in your application without using the Digital Paint.


If you are using LEADTOOLS COM Object, you can use the DrawRectangle
method. For more information about it, please refer to the "DrawRectangle method (ILEADRasterFXD)" topic in the LEADTOOLS Main COM Object Help file.


If you are using LEADTOOLS ActiveX, you can also use
the DrawRectangle method. For more information about this method, please refer
to the "DrawRectangle method (Main Control)" topic in the LEADTOOLS Main OCX Help file.

Do these methods allow me to apply opacity to the fill? I was under the impression that I needed digital paint in order to accomplish this.

thanks

If you don't want a variable opacity (solid color), then you can use the Main Control:

LEAD1.DrawPenColor = RGB(255, 0, 0)
LEAD1.DrawFillColor = RGB(255, 0, 0)
LEAD1.DrawFillStyle = DRAWFILLSTYLE_SOLID
LEAD1.DrawRectangle 50, 50, 100, 100

However, if you DO want variable opacity, so that the rectangle is see-through, then you must use the digital paint control:

LEADPaint1.Shape.BorderColor = RGB(255, 0, 0)
LEADPaint1.Shape.BackgroundColor = RGB(255, 0, 0)
LEADPaint1.Shape.Opacity = 150
LEADPaint1.Shape.DrawRect 50, 50, 100, 100
