color management disabled then you often get an image that does not look very good. +The colors do not look natural, the contrast is bad, the image is too dark etc. + +The reason for this is that each device interprets a color e.g. represented by a red, green and blue value in +its own way. +<p> +When you want a display or a printer to produce an image with the colors of a photo that you want to scan with a scanner +then you need to tell your system how each device interprets colors. This is done with ICC/ICM profiles. +When you have at least an ICC/ICM profile for your scanner and for your display then you can enable the color management of XSane. +Please make sure that you filled out the +<a href="sane-xsane-setup-color-management-doc.html">color management setup</a> +correct before you enable it, otherwise you will get a lot of error messages. +<br> +<br> +<br> +<a NAME="ENABLE_CMS"></a><b>Enable color management:</b><br> + +<img SRC="xsane-enable-color-management.jpg" alt="enable-color-management"> + +<blockquote> +To enable the color management activate it in the <i>Preferences</i> menu. +When you do this then the gamma, contrast and brightness options are disabled. +</blockquote> + +<a NAME="CMS_FUNCTION"></a><b>Color management function:</b><br> + +<img SRC="xsane-cms-function.jpg" alt="cms-function"> +<blockquote> +There are three different functions available when color management is enabled: +<ul> + <li> + <a NAME="EMBED_ICM_PROFILE"></a><b>Embed scanner ICM profile</b> + <br> + The image is saved with the original image data, no color transformation is + done.
