With the completion of the changes, RGB now means linear color and sRGB means non-linear color in terms of their respective colorspaces.</p>
60 <p>ImageMagick supports color profiles, however, for images without a profile or a declaration of colorspace, ImageMagick assumes non-linear sRGB. Most image processing algorithms assume a linear colorspace, therefore it might be prudent to convert to linear color or remove the gamma function before certain image processing algorithms are applied. For example,</p>
63 convert myimage.jpg -colorspace RGB -resize 200% -colorspace sRGB mybigimage.jpg
66 <p>To declare that an image is linear RGB rather than sRGB, you can use the set option:</p>
72 <p>Afterwards, the verbose information for the output file lists the colorspace as RGB. This only works on image types containing meta data that distinguishes between linear RGB and non-linear sRGB, such as PNG and GIF. Therefore, if the above command is run with a JPG or TIF output format, the verbose information for the colorspace still shows sRGB. In order to properly have the JPG output know that it is linear RGB, include an appropriate color profile.</p>
81 <p>The same concept is needed when separating channels. Normally, the conversion to separate each channel of an sRGB color image produces separate linear grayscale images. However the same concept can be applied, if it is desired to keep the separate channels as non-linear grayscale. For example, the following produces non-linear grayscale channels.</p>
94 <p>In the above example, the result is darker than the original, because the channels were separate as linear gray and subsequently combined as linear color. In order to return the channels back to sRGB, one must change the colorspace from RGB back to sRGB after the <code>-combine</code> step.</p
