Hello -
I’m trying to add a metafile (EMF, WMF) to a presentation and have it maintain its full vector clarity. I know that PowerPoint natively supports metafiles. If I add the same image manually and zoom way in it is crystal clear. When I add it via the methods that I think I have to use in Aspose.Slides, it appears the image is converted to a raster format and thus zooming make it look all aliased. Our code engine can output metafile images and we’d love to have these inserted in native format in PowerPoint using Aspose.
Details:
I’m using C#
I’m using the Aspose.Slides.Pptx namespace and and working with pptx presentations.
I’m using the .Net 4.0.30319 runtime and Aspose.Slides version 8.3.0.0.
The code I’m using is very simple. Here it is:
Note:
Pres is a Aspose.Slides.PresentationEx instance
slide is a Aspose.Slides.SlideEx instance (the slide i’m working with)
shp is a Aspose.Slides.ShapeEx instance (a shape I’m using to identify where the metafile should go)
//load the metafile
var mf = new System.Drawing.Imaging.Metafile(“EMFTEST.emf”);
//create the ImageEx
Aspose.Slides.Pptx.ImageEx imgx = Pres.Images.AddImage(mf);
//add the PictureFrame
slide.Shapes.AddPictureFrame(PP.ShapeTypeEx.Rectangle, shp.X, shp.Y, shp.Width, shp.Height, imgx);
//set the image in the PictureFrame
shp.FillFormat.PictureFillFormat.Picture.Image = imgx;That’s it! What am I doing wrong? I saw in the old PPT forum that metafiles should be added using a “Picture” object not an “Image” object - but that was a very outdated comment. Any help would be great appreciated. Thanks.
