LEADTOOLS Color Conversion Color Space features can convert images from any color resolution to any other color resolution. Whether you are working with medical images, scanned documents or digital photographs, LEADTOOLS can help you provide the correct color depth for the hardware your clients are using (from 1-bit to 64-bit*), with multiple dithering methods using various palette options. These functions are included with LEADTOOLS Raster, Vector, Medical, and Document Imaging products.
Use flexible palette options, including LEAD's fixed palette, an auto-optimized palette, or a user defined palette.
Apply palettes to a single image or to an entire list of images.
Convert, separate to and reconstruct images from individual RGB, BGR, CMYK, CMY, HSV, HSL, YUV, YIQ, CIELAB, XYZ, YCCK, Y41P, UYVY, YUY2, YVU9, ARGB4444, IHS and YCC color planes using LEAD's built in conversion functions, ICC color profiles or Emulation Tables.
Window-level 12- and 16-bit grayscale images. The support LEADTOOLS toolkits provide allows you to select the desired range of bits to be used for display or processing. *
The Color Conversion SDK supports the following conversions:
|Source Color Space||Can be converted to||Conversion method||Recommended|
|RGB||Any other color space.||Built-in, ICC profiles, or emulation tables, depending on the destination color space.|
|BGR||Any other color space.||Built-in, ICC profiles, or emulation tables, depending on the destination color conversion.|
|YUV||Any other color space.||Built-in.|
|CMYK||Any other color space.||Emulation Tables (one way CMYK => RGB)||The best conversion is through the ICC Profiles (USE_ICC). This is because of the nature of the CMYK conversion, which is machine-dependant. You can use profiles that vary in the degree of black color (ink) generation.|
|HSV||Any other color space.||Built-in.|
|HSL||Any other color space.||Built-in.|
|YIQ||Any other color space.||Built-in.|
|LAB||Any other color space.||Emulation Tables (one way CMYK => RGB).||For two-way conversion (RGB to LAB and vice versa), the best solution is with emulation tables and built-in conversions. These preserve the colors better. However, for one-way conversion you can use ICC profiles.|
|XYZ||Any other color space.||Built-in.|
|YCCK||Any other color space.||Built-in.|
|Y41P||Any other color space.||Built-in.|
|UYVY||Any other color space.||Built-in.|
|YUY2||Any other color space.||Built-in.|
|YVU9||Any other color space.||Built-in.|
|YCC||Any other color space.||Built-in.|
|ARGB4||Any other color space.||Built-in.|
|IHS||Any other color space.||Built-in.|
The toolkit comes in Win32 and x64 editions. The environments supported depend upon the specific product, platform and function. For more information, refer to Supported Platforms / Operating Systems.
