The Convertion section is embedded in the Graphics tab of the Profile Manager and allows you to set the options for converting colors of text and graphics, indexed images or high color images to grayscale or monochrome (black/white) color.
How to convert content?
This group allows you to choose a predefined conversion preset or use a custom one. By default there are several predefined conversion presets defined but you can add new or manage those by clicking on New / Manage. You can read more about predefined conversion presets in the Manage Presets->Conversion help section. A predefined conversion preset can be used by multiple profiles, while Custom settings only affect the current profile.
During conversion, the colors for text and graphics, indexed images or high color images will be converted to grayscale or monochrome (black/white) colors depending on which option you select.
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.
The threshold value is used to convert to monochrome color. It can range between 0 and 256; the default value is 128. All colors less the threshold value will be converted to black and all colors above the threshold value will be converted to white.
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.
