![]() WinTopo provides 5 thinning methods, each utilising different mathematical algorithms and producing different results: The approach used by WinTopo is to reduce thick or blobby regions down to single pixel width items, so that the image is transformed into lines of pixels. For example, the lines may be fairly obvious to a human observer, until the image is magnified, at which point it may be seen that the lines are several pixels wide, uneven along the edges and fade out into the background. In order for WinTopo to extract vectors from a raster image it needs to determine which parts of the image constitute lines, and where those lines start and end. ![]() Extraction of real vectors from the pixel lines.Thinning of the raster image to single pixel width lines.WinTopo employs a two stage vectorisation process: Whether you are using WinTopo Pro, or the greatly acclaimed WinTopo Freeware, you will achieve exceptional results. WinTopo is a high quality tool for converting raster images to vector data.
