Expression is a vector editor, mixing bitmap and vectors. Used mostly to create quickly illustration.
There are really good things, like the fact that a bitmap (or a set of vector), is used as brush for another verctor. The definition of the brush, is like a sound in a sound editor, there is loop range (for repeating motif), increase, decrease, wave amplitude variation on stroke shape, etc...
29 June 2004 Expression 3.3 This program is now available free in PC and Win forms. For those who do not know, it is a vector based painting program and one of the best programs available for free on the net at present. There are many things that it does that Inkscape is heading towards. The company was taken over by Microsoft last year and the program is now known as Microsoft Expression. The following is taken from Sue Chastains site at http://graphicssoft.about.com/cs/illustration/gr/expression.htm and the program itself can be downloaded at http://www.microsoft.com/products/expression/default.asp?pg=home. The PC version of the download is 57.5MB and became available about a week ago. Who knows how long it will stay available.
