Hi,
I use VB dotnet , but still the COM library (v.14).
Can you tell me how to create a new system.drawing.image from a leadraster.bitmap?
In VB6, I used the "setpicture" and "getpicture" methods to put a lead bitmap y a windows control , like a picturebox.
But in dotNet I dont know how to do it.
I tryed getDIB but without good results.
Thanks in advance

Hello,

You can create a new System.Drawing.Image object from a LeadRaster bitmap by using the following C# code:

======================================

System.Drawing.Image image1;

stdole.IPictureDisp pic = axLEADRasterView1.Raster.GetPicture();

image1 = System.Drawing.Image.FromHbitmap(new IntPtr(pic.Handle), new IntPtr(pic.hPal));

pictureBox1.Image = image1;

======================================

Regards,

How can I do the same thing using a RasterImage object as the source?

DanOls,

I've used the RasterImage.ConvertToGdiPlusImage() method for that purpose. It's very quick, too, at least in v. 15.

Steve,
Thank you for the feedback.

Also, if you are using our .NET 14.5 classes, you can convert a LEAD RasterImage to System.Drawing.Image using the ChangeToGdiPlusImage Method.

In LEADTOOLS 17 and later, RasterImage does not contain the ChangeToGdiPlusImage(). Instead, use the Leadtools.Drawing.RasterImageConverter.ChangeToImage() method. This will return a System.Drawing.Image. If you need a copy of the image instead, you can use RasterImageConverter.ConvertToImage().
