Widget that displays an image file on the screen using a location and filename.
For images stored in the app's directory, location should be set to app, and filename should be set to the name of the image file.Construct a new Image Object.
Reloads the image from disk. This is needed to clear the UI drawing cache. Should only be used if a new image is written over an existing one of the same name that has been used in the current run of the app.
Changes the size of the image. If either width or height is set to 0, the image will be scaled to the other width/height, maintaining the aspect ratio.
