ImageSize

ImageData.ImageSize property

Gets the information about image size and resolution.

public ImageSize ImageSize { get; }

Remarks

If the image is linked only and not stored in the document, returns zero size.

Examples

Shows how to resize a shape with an image.

// When we insert an image using the "InsertImage" method, the builder scales the shape that displays the image so that,
// when we view the document using 100% zoom in Microsoft Word, the shape displays the image in its actual size.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
Shape shape = builder.InsertImage(ImageDir + "Logo.jpg");

// A 400x400 image will create an ImageData object with an image size of 300x300pt.
ImageSize imageSize = shape.ImageData.ImageSize;

Assert.AreEqual(300.0d, imageSize.WidthPoints);
Assert.AreEqual(300.0d, imageSize.HeightPoints);

// If a shape's dimensions match the image data's dimensions,
// then the shape is displaying the image in its original size.
Assert.AreEqual(300.0d, shape.Width);
Assert.AreEqual(300.0d, shape.Height);

// Reduce the overall size of the shape by 50%. 
shape.Width *= 0.5;

// Scaling factors apply to both the width and the height at the same time to preserve the shape's proportions. 
Assert.AreEqual(150.0d, shape.Width);
Assert.AreEqual(150.0d, shape.Height);

// When we resize the shape, the size of the image data remains the same.
Assert.AreEqual(300.0d, imageSize.WidthPoints);
Assert.AreEqual(300.0d, imageSize.HeightPoints);

// We can reference the image data dimensions to apply a scaling based on the size of the image.
shape.Width = imageSize.WidthPoints * 1.1;

Assert.AreEqual(330.0d, shape.Width);
Assert.AreEqual(330.0d, shape.Height);

doc.Save(ArtifactsDir + "Image.ScaleImage.docx");
