Is Inkscape a replacement for The GIMP or Photoshop?
In most cases, no. They’re used for two very different things. Inkscape is used for creating vector drawings, such as laying out a poster or creating a fancy logo, whereas bitmap editors are for working on raster images, such as touching up a photograph. In many projects, you would need to use both Inkscape and a bitmap editor (such as GIMP), for example, to add bitmap effects to an image exported from Inkscape. However, currently bitmap editors are often used for common tasks they are not well equipped for, such as creating web page layouts, logos, or technical line art. In most cases, this is because users are not aware of the power (or even the existence) of the modern vector editors. Inkscape wants to amend this situation, and to raise a vector editor to the status of an essential desktop tool for everyone, rather than an exotic specialized tool that only professionals use.
