To convert an image to the paletted color modeĬhoose one of the following color palette types from the Palette list box: All images that you include in the batch are changed using the color palette and conversion options you specify. Before you perform a batch conversion, you must open the images in Corel PHOTO-PAINT. You can change multiple images to the paletted color mode simultaneously. You can also remove the presets you have added.Ĭonverting multiple images to the paletted color mode You can add and remove as many conversion presets as you want. Because the palette has a maximum of 256 colors, emphasizing a seed color reduces the number of colors that fall outside the range sensitivity.Īfter you choose a color palette and set the dithering and range sensitivity for the changing of an image to the paletted color mode, you can save the selected options as a conversion preset that you can use with other images. You can also specify how much emphasis to place on the range sensitivity. The seed color, and similar colors that fall within the range settings, are included in the processed color palette. When you change an image to the paletted color mode using the Optimized palette, you can choose a seed color, or base color, and a range sensitivity for the seed color. Setting the color range for a custom color palette If your image contains only a few colors and simple shapes, you do not need to use dithering. Jarvis, Stucki and Floyd-Steinberg are methods of error diffusion. Error diffusion scatters pixels randomly, making edges and colors softer. Ordered dithering approximates color blends by using regular dot patterns as a result, solid colors are emphasized and edges appear harder. The relationship of one colored pixel to another creates an optical mix, so you perceive additional colors.ĭithering can be done by distributing colors either regularly or randomly.

Dithering creates additional colors and shades from an existing palette by interspersing pixels of different colors. If the original image contains many colors, you can use dithering to create the illusion of seeing more than 256 colors. Paletted images can only contain up to 256 different colors. The color palette you use to convert the image is called the processed color palette, and it can be saved for use with other images.įor more information about creating custom color palettes, see Working with color. If you choose the Optimized color palette, you can also edit the palette by specifying a range sensitivity color. When you change an image to the paletted color mode, you use a predefined or a custom color palette and then edit the palette by replacing individual colors. Paletted color mode is an 8-bit mode that stores and displays images by using up to 256 colors.Ĭhoosing, editing, and saving a color palette As a result, the paletted image contains less data than the original, and it has a smaller file size.

These values are stored in a compact color table, or palette.

When you convert a complex image to the paletted color mode, a fixed color value is assigned to each pixel. The paletted color mode, also called indexed color mode, is frequently used for GIF images on the web.
