This is one of two basic lith filters and creates an image that has only black or white areas.
Any pixel in the image that has a brightness that lies between the two thresholds set is changed to black and those outside the thresholds are changed to white.

This is the second of the basic lith filters and creates an image that has only black and white areas but is the opposite of Black/White.
Any pixel in the image that has a brightness that lies between the two thresholds set is changed to whiteand those outside the thresholds are changed to black.

This is the first of the more advanced filters and creates an image with some pixels unaltered and others changed to black or white.
Any pixel in the image with a brightness that lies between the two thresholds is left unaltered, those that lie below the lower threshold are changed to black and those that lie above the upper threshold are changed to white.

This is the second of the more advanced filters and creates an image with some pixels unaltered and others changed to black or white.
Any pixel in the image with a brightness that lies between the two thresholds is left unaltered, those that lie below the lower threshold are changed to white and those that lie above the upper threshold are changed to black.

This is the fourth of the more advanced filters and creates an image with some pixels unaltered and others changed to white.
Any pixel in the image with a brightness that lies between the two thresholds is changed to white, those that lie outside the thresholds are left unaltered. It is the opposite of the Cut To White filter above.

This is the first of the Coloured filters. It is quite simple and produces a result similar to Black/White and White/Black but uses user-selected colours instead of black and white. When this filter is selected from the combo box the Colour Select Panel displays two colour patches, Inside Colour and Outside Colour, that represent the colours between the thresholds and outside them. To select a colour click on the colour patch to open a Colour Chooser. The Swap button will swap the colours.

This filter is similar to the Cut to Black and Cut to White filters but allows the user to select the colour that will be used for pixels that are outside the thresholds, the pixels between the thresholds will be left unchanged. When this filter is selected from the combo box the Colour Select Panel displays a colour patch, clicking on this will open a Colour Chooser allowing the selection of the colour.

This filter is the opposite of the Cut To Colour filter above, the pixels that lie between the thresholds are changed to the selected colour and those outside are left unaltered. When this filter is selected from the combo box the Colour Select Panel displays a colour patch, clicking on this will open a Colour Chooser allowing the selection of the colour.

This filter is similar to Cut to Colour but allows the user to select different colours to be used above the upper threshold and below the lower threshold, the pixels between the thresholds are left unchanged. When this filter is selected from the combo box the Colour Select Panel displays two colour patches, Highlights will be used above the upper threshold and Shadows will be used below the lower threshold. Clicking on a patch will open a Colour Chooser and allow the colour to be selected.

This filter produces a simple posterisation effect. Three colours are supplied along with the two thresholds. The first colour is used to colour all the pixels in the original image that are brighter than the upper threshold, the second colour is used for all pixels in the original that lie between the thresholds and the third colour is used to colour those pixels that are darker than the lower threshold. Clicking on the appropriate colour patch will open a colour chooser alowwing selection of the desired colours.
