Resize.CalculateProportionalDimensions Method (Bitmap, Int32 %, Int32 %, ResizeMode)

Syntax

Public Shared Sub CalculateProportionalDimensions ( _
	srcBitmap As Bitmap, _
	ByRef destWidth As Integer, _
	ByRef destHeight As Integer, _
	mode As ResizeMode _
)

public static void CalculateProportionalDimensions(
	Bitmap srcBitmap,
	ref int destWidth,
	ref int destHeight,
	ResizeMode mode
)

Remarks

Use this method if you need to get the exact dimensions of the bitmap after proportional resize. This method recalculates specified width and height to preserve the aspect ratio of the input bitmap respecting the specified ResizeMode. Note, destWidth and destHeight are both in and out, and these values are changed by the method.

For example, you need to make sure that the bitmap after resize will fit 640x480 rectangle. In this case you should pass the following values:

• srcBitmapAn instance of the bitmap which you are going to resize.
• destWidthAn integer variable which is equal to 640.
• destHeightAn integer variable which is equal to 480
• mode Fit

After you run this method, variables you pass as destWidth and destHeight will store recalculated dimensions.
