Simple interactive object extraction (SIOX) is an algorithm for extracting foreground objects from color images and videos with very little user interaction. [1] It has been implemented as "foreground selection" tool in the GIMP (since version 2.3.3), as part of the tracer tool in Inkscape (since 0.44pre3), and as function in ImageJ and Fiji (plug-in).
The clone tool can remove objects by copying a nearby background. The user selects a matching location as the source, then paints over the element to be hidden. [1] A typical use for the tool is in object removal – more colloquially, "airbrushing" or "photoshopping" out an unwanted part of the image.
However, Inkscape is capable of producing color images by decomposing each channel into several black and white images and tracing them separately with Potrace. The commercial Total Vectorize program also uses Potrace as its core. Potrace is licensed under the GNU General Public License v2.0 or later.

Inkscape began in 2003 as a code fork of the Sodipodi project. [6] Sodipodi, developed since 1999, was itself based on Raph Levien's Gill (GNOME Illustration Application). [7] One of the main priorities of the Inkscape project was interface consistency and usability by following the GNOME human interface guidelines. [6]
This is the standard blend mode which uses the top layer alone, [3] without mixing its colors with the layer beneath it: [example needed] (,) =where a is the value of a color channel in the underlying layer, and b is that of the corresponding channel of the upper layer.
In the window that appears, click on the Flat color button (see 4 on screen). Then change the color with the cursor or enter the RGBA code of a color. (A=alpha, normally 255=opaque). Note: you can select several zones at the same time, and change their color at the same time, by clicking whilst pressing the shift key.
An example of converting an image from color to grayscale. It is possible, using the software, to change the color depth of images. Common color depths are 2, 4, 16, 256, 65,536 and 16.7 million colors. The JPEG and PNG image formats are capable of storing 16.7 million colors (equal to 256 luminance values per color channel).
