An image layer represents an image from a photo or other image file. It can be moved, resized, or rotated. A new image layer can be created by clicking the Image icon on the Tools tab of the toolbar.
Size Image Effects
Use the Width and Height fields to set the size of the overlay image in pixels. Rotation
The image size can also be changed by dragging the image's scale handles on the canvas viewer when the image layer is selected.
By checking the "Keep Aspect Ratio" checkbox, the width to height ratio of the image will be maintained when changing the scale using the properties panel or scale handles on the canvas.
The image can be rotated using the canvas widget's rotate handle, or by specifing a value in the Rotation: field. Flipping
The image can be flipped (or mirrored) using the Flip Horizontal and Flip Vertical buttons. Opacity
Use the Opacity: slider to adjust the transparency of the overlay image. Sharpness
When a selection is deleted from the overlay image, the Sharpness slider can be used to blur the edges of the overlay image.
An effect can be applied to the overlay image by checking the Use Effects checkbox.
Use the Choose an Effect pulldown list to select the effect to be applied.
