Resize Class

Syntax

Public NotInheritable Class Resize _
	Inherits BitmapTransform

public sealed class Resize : BitmapTransform

Remarks

Using this class you may resample the bitmap: specify Width and Height properties, then apply the transform, and it will return resized bitmap. If you set some of these properties to 0, this property is automatically calculated to preserve the aspect ratio of the image.

Essential parameter of all the geometric Transforms (including resizing) is an interpolation algorithm. It specifies how to calculate intermediate points. Different algorithms produces different quality, but as usual the higher quality it produces, the slower algorithm works. You can select interpolation algorithm with InterpolationMode property.

This class provides interesting feature - you can resize not only entire bitmap, but even a portion of this bitmap. This way you can avoid edge effects (which will arise if you first crop and then resize the bitmap). It is important when you need to stitch several resized portions seamlessly (for example, during optimized drawing). To enable this feature, set CropEnabled property to true and fill CropRectangle with necessary values.

All the coordinates and sizes are measured in units specified with Unit property.
