Conversion

Options on this window are used to configure color conversion for text and graphics, indexed images and high color images.

The dialog can be opened by pressing the Configure button from the Graphics window in Printing Preferences.

Enable conversion

If checked colors for text and graphics, indexed images or high color images will be converted. That means the images will be added in the PDF file with converted to grayscale or monochrome (black/white) color.

Convert to grayscale

Each color will be converted to a gray value between 0 and 256. You can convert to grayscale texts and graphics, indexed and high color images.

Convert to monochrome

Each color will be converted to black or white. You can convert to monochrome texts and graphics, indexed and high color images. For images you can select a dithering algorithm for better results.

Treshold

The treshold value is used to convert to monochrome color. It can range between 0 and 256; the default value is 128. All colors less the treshold value will be converted to black and all colors above the treshold value will be converted to white.

Dither

When converting images to monochrome you can choose a dithering algorithm for better results. Available algorithms are: Floyd & Steinberg error diffusion, Bayer ordered dispersed dot 4x4, Bayer ordered dispersed dot 8x8, Ordered clustered dot 6x6, Ordered clustered dot 8x8, Ordered clustered dot 16x16.

By default, the Floyd & Steinberg error diffusion dither method is used to dither monochrome images. Dithering is not available for text and graphics.
