Parameters

canvasImage

References the canvas image.

transparency

The transparency amount between the image and the canvas. Valid range is from 0 to 100. When set to 0, only the canvas image displays, and when set to 100, the canvas image is barely visible.

emboss

Apparent depth of the canvas image. Valid range is from 0 to 200. When Transparency is at 100, and Emboss is 0 only the image displays. Increasing Emboss increases the apparent depth of the canvas image.

xOffset

The X distance between the canvas origin point and the image origin point (in pixels). Valid range is from -Canvas image width to +Canvas image width.

yOffset

The Y distance between the canvas origin point and the image origin point (in pixels). Valid range is from -Canvas image height to +Canvas image height.

tileOffset

The amount to shift every row of the canvas image from the origin. This parameter is not used when Flags is set to CanvasCommandFlags.TileFit.

flags

Flags that identify how to distribute the canvas image with respect to the image and how to handle resizing.

This procedure run a CanvasCommand of the image using canvasImage.
