To use Patternshop, you need Windows 98 or above, an open GL compatible graphics card and an Internet connection.
Patternshop handles TIFF, PNG and JPG formats, and is compatible with most image processing programs.
As well as these three formats, Patternshop uses its own file format, PTS, to save documents.
Note: We recommend using formats which allow for transparency for your motifs, such as TIFF or PNG.
