# Adding image with setting it's opacity

How to add image in Aspose.Words and set it’s opacity? Is there is any property or something?

For example, the following code of Aspose.Imaging for .NET API creates a blank canvas of type PNG with transparency and draws another image over it while specifying the desired opacity (ColorMatrix.Matrix33). Please note, 0.3f means 30% so you may set it to any desired value. Moreover, you may change the opacity for every next image if you set this property in a loop.

using (PngImage pngImage = new PngImage(1500, 1500, PngColorType.TruecolorWithAlpha))
{
ColorMatrix cmxPic = new ColorMatrix();
cmxPic.Matrix33 = 0.3f;
ImageAttributes iaPic = new ImageAttributes();

{
Graphics gr = new Graphics(pngImage);
}
pngImage.Save(“D:/ newPng.png”);
}


After that your Image is processed you will then be able to insert image inside Word document and set its different parameters:

Document doc = new Document("E:\\Temp\\in.docx");
DocumentBuilder builder = new DocumentBuilder(doc);
builder.MoveToDocumentEnd();
Shape shape = builder.InsertImage("E:\\Temp\\Aspose.Words.jpg");
shape.Fill.Opacity = 0.7;
shape.Stroke.On = true;
shape.Stroke.Color = doc.Theme.Colors.Accent1;
shape.Stroke.Weight = 5;
shape.Stroke.Opacity = 0.7;
doc.Save("E:\\Temp\\19.12.docx");


Hope, this helps in achieving what you are looking for.

Is there is any possible way to use only Aspose.Words for this task?
