Converting images to the Paletted color mode

The Paletted color mode is an 8-bit color mode that stores and displays images using up to 256 colors. Converting a complex image to the Paletted color mode reduces file size — especially important for Internet publications — and allows more precise control over the colors used throughout the conversion process.

When you convert an image to the Paletted color mode, you can choose from different color palette types. Choose a predefined palette or create your own customized palette based on the colors displayed in your image. For more precise control over the colors contained in the palette, you can specify the number of colors and the range sensitivity to apply throughout the conversion.

Smoothing

When you smooth an image, CorelDRAW analyzes the color differences around each pixel in the image and blends the color transitions where abrupt color changes occur. Smoothing creates a softly blurred image but helps produce a more accurate palette.

Dithering

Dithering enhances the appearance of photographic images by using a limited Color Palette. Dithering places pixels with specific colors or values relative to other pixels of a specific color. The relationship of one colored pixel to another helps to create the appearance of additional colors that do not exist in the Color Palette. There are two types of dithering: error diffusion and ordered dithering. Error diffusion scatters pixels irregularly, making edges and colors softer. Ordered dithering approximates color blends using fixed dot patterns; as a result, solid colors are emphasized and edges appear harder.

Range sensitivity

If you convert an image to the Paletted color mode using an optimized palette, you can specify a range sensitivity color. This color acts as a target color for the conversion, meaning more colors in the specified color's range are used in the conversion. You can determine the importance of the range sensitivity color and customize its appearance.

Batch conversion

You can convert multiple files to the Paletted color mode using batch conversion. You can specify which files to convert and preview each image before applying the conversion.
