Inkscape

grayscale

Asked by Talita on 2008-06-17

Does the grayscale tool work only for the drawings designed in the Inkscape?
Why is that when I try to apply the grayscale tool on an imported image nothing happens?
Thank you, i'll wait for an answer

I believe the grayscale effect does not work on bitmapped images (jpeg, tif, gif, bmp, etc.), only on vector objects (svg, pdf, ai, etc.)

Actually, you can convert an image (jpeg, tif, gif, bmp, etc.) to grayscale in Inkscape. You need to apply a filter effect to do it. I believe it's Color Matrix>Saturation.

An alternative method outside of Inkscape would be to use Imagemagick: convert color.png -colorspace Gray grayscale.png. Why this wasn't included in the Imagemagick raster effects in Inkscape is beyond me. Seems like this would be a common thing. Too bad we didn't have the ability to add extra Imagemagick commands to the drop down menu. That would be neat. Oh well. :)
