Image Mask combine

Post by fnaudeau » Thu Aug 18, 2016 11:07 pm

Hello,

I'm migrating from LeadTools to GDPicture, and I'm looking for an equivalent of FeatherAlphaBlendCommand :

Combines image data from two images with feathering. The two images can be combined with variable opacity applied by specifying the region of a fade mask image.

It's useful to merge an image to another based on a masked region.
Is there an equivalent with GDPicture ?


Thanks.
Frédéric

Here an example:

Code: Select all

using (GdPictureImaging gdPictureImaging = new GdPictureImaging())
            {
                int imageMask = gdPictureImaging.CreateGdPictureImageFromFile("e:\\mask_test\\Anniversaire1_mask0.png");
                int imageBackground = gdPictureImaging.CreateGdPictureImageFromFile("e:\\mask_test\\Anniversaire1.jpg");
                int imageLayer = gdPictureImaging.CreateGdPictureImageFromFile("e:\\mask_test\\layer.jpg");
                gdPictureImaging.DrawGdPictureImageOP(imageLayer, imageMask, 0, 0, gdPictureImaging.GetWidth(imageMask), gdPictureImaging.GetHeight(imageMask), Operators.OperatorAnd, System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic);

                gdPictureImaging.SetTransparencyColor(imageMask, Color.Black);
                gdPictureImaging.DrawGdPictureImage(imageMask, imageBackground, 0, 0, gdPictureImaging.GetWidth(imageBackground), gdPictureImaging.GetHeight(imageBackground), System.Drawing.Drawing2D.InterpolationMode.NearestNeighbor);
                gdPictureImaging.ReleaseGdPictureImage(imageMask);
                gdPictureImaging.ReleaseGdPictureImage(imageLayer);
                gdPictureImaging.SaveAsJPEG(imageBackground, "e:\\mask_test\\result.jpg", 90);
                gdPictureImaging.ReleaseGdPictureImage(imageBackground);
            }
