What does Select Color Layers do?By default, Scan2CAD is “color blind” and sees raster images as non-white areas on a white background. When you activate Select Color Layers some functions become “color aware” and only work on Selected Colored parts of the image. For example:
Without Color Layers Selected, Scan2CAD sees all the non white areas of the image as one color and only removes speckles that are entirely surrounded by white space. With Color Layers Selected, Scan2CAD only sees Selected Colored speckles and removes these regardless of the background color they are on.
Without Color Layers Selected, no despeckling has taken place because Scan2CAD sees the whole image as one color. With all the colors on the image selected as Color Layers, any area of any color smaller than a given size has been treated as a speckle and removed.
Without Color Layers Selected, Scan2CAD sees all the non white areas of the image as one color and vectorizes them all to black. With Color Layers Selected, Scan2CAD only sees and vectorizes Selected Color Layer parts of the raster image.
