Adjust the transparency more if needed:.And you get beautiful progressive transparency:.Select both the rectangle and the object under it and apply the gradient rectangle as a mask ( Object > Mask > Set):.Fill the rectangle with a vertical gradient going from solid black to solit white:.Take your image and make a duplicate, place the duplicate on bottom:.Update: I was wrong, it is possible to do much better with vectors, read on: The graphics we will create will look like this:Ī vector application in not as powerful for this job as a raster editor, but it allow a lot of things to be made. Of course, it can be also made with 3D graphics, but this is out of the scope of this tutorial. Depending of your base image, style of work and target, it can be done in vectors (Inkscape) or raster (GIMP).
This is a trick abused often: take an image and create its reflection on a surface to obtain a kind of perspective effect. Reflecting images on surfaces with Inkscape and GIMP Article updated: Since I wrote this article I learned a very neat trick about I was not aware, so the article is updated to include it, it is about applying a mask to get the partial transparency for reflection in Inkscape.
