Whether we capture using camera or an application called TuxPaint or Screenshot, the images have been captured digitally based on the resolution of the computer or mobile screen; this is indicated in terms of pixels.  Such images are called raster images and they are dependent on the resolution of the device for their quality.  All raster images are those that involve capturing some underlying image or object using various devices.  For more information on raster images, see [https://en.wikipedia.org/wiki/Raster_graphics here]. GNU Image Manipulation Program (GIMP) is an image editing software, that can edit and compile raster images.  There is another kind of digital image called the [https://en.wikipedia.org/wiki/Vector_graphics vector] which is not discussed in the toolkit.  Vector images involve creating drawings based on defined mathematical shapes; this can be defined in terms of the shapes and is not governed by the resolution of the device.  Inkscape is a tool that can be used to create and edit vector images.
