Here you specify how the image is displayed in the plot.
Display style
Stretch mode
Image origin
Image size
The display style decides how the colours of the images are shown.
Copy Colours
Shows the colours of the top picture only
Copy Colours with Transparency
Shows the colours of the topmost picture's colours, but you can choose one transparent colour. Areas of your picture that has this colour will be transparent, so you can see the image below.
Blend colours
The colours of the different layers will be mixed.
When a pixel image is drawn in a window such that the image is maller in at least one direction, at least some pixels in the original image will map to a single displaced pixel. The stretch mode determines the colour of those pixels.
Halftone
Maps pixels from the source rectangle into blocks of pixels in the destination rectangle. The average colour over the destination block of pixels approximates the colour of the source pixels.
Color-on-color
Deletes all eliminated lines of pixels without trying to preserve their information.
Black-on-white
Performs an operation using the colour values for the eliminated and existing pixels. If the bitmap is a monochrome bitmap, this mode preserves black pixels at the expense of white pixels.
The default values for the origin of the image are taken from the *.dfs/*.dt data file.
The image size is defined by the pixel width and height multiplied by the number of pixels in the image for the two directions.
