Graphics Printer Functions

What each function of the graphics printer is

DITHERING: You can choose between

-ORDERED. Prints a square block for each pixel shown on screen.

HALF TONE Changes the size of the pixel according to its darkness.

-FLOYD-STEINBERG. Dithers the Amiga to make the printout look like it uses more colours

SCALING: There are two options that you can choose from

-FRACTION Will use the page size that is defined by the width and height.

-INTEGER Prints the image in a square shape, but it may not fit on the page.

IMAGE: Can be set to

-POSITIVE This will make it look like your picture.

-NEGATIVE All the colours/shades are reversed, so black turns into white etc.

ASPECT: You can choose from

-HORIZONTAL Prints out the image facing up on the page.

-VERTICAL Prints the image "on its side". Useful if you want to print in A5.

SHADE:

-BLACK AND WHITE Prints in black and white.

-GREY SCALE 1 Converts colour to different shades of grey.

-GREY SCALE 2 Uses only four shades of grey.

-COLOUR Obviously, prints in colour.

THRESHOLD: This sets how dark a colour is before it is printed as black. Only of use to black and white printers.

DENSITY: How close together the graphics are printed out at- a higher density means more detail. The higher the density the longer it takes to print.

SMOOTHING: In art packages it is known as anti-aliasing. This attempts to make jagged edges smooth.

CENTER PICTURE: Prints in the middle of the page.

COLOUR CORRECTION: Reduces the number of colours that the colour printer has to interpret. This can help make the image look slightly better.

LEFT EDGE: The amount of space that is left for the left margin.

LIMITS:

-IGNORE Does not use any limit to the image.

-BOUNDED Parts of an image that go over the limit are not printed.

-ABSOLUTE Allows you to print small pictures.

-PIXELS Prints image of an unusual size that are larger than can be displayed.

-MULTIPLY Useful for printing on a wide carriage printer. It expands the picture to fill the limit.

WIDTH AND HEIGHT: Sets the size of the paper limits.
