Before	After

Remove Speckles cleans up the raster image by removing speckles from it.

Remove speckles from the whole image

1.	Click or select Raster Effects Menu > Clean > Remove Speckles.

Warning: If you display a large section of your raster image in the Preview Window this function may operate very slowly.

As you move the slider you will see speckles smaller than the speckle size disappearing in the Preview Window.

Adjust the speckle size if necessary.

Scan2CAD removes all speckles that are smaller than the speckle size you have selected.

Click to undo.

Remove speckles from part of the image

If you only want to despeckle part of the image, choose the part you want to despeckle by windowing it or zooming into it, then follow the steps above. In Step 5, ensure the Apply changes to Full Image option is not selected.

Special note for color images

If you are working with a color raster image you can modify the way that Remove Speckles works by selecting a Pick Color or Color Layers.

Before	After: no Pick Color, no Layer Colors

If no Pick Color or Layer Colors are selected, Scan2CAD removes speckles of any color that are entirely surrounded by white space.

Before	After: Pick Color = blue

If a Pick Color is selected, Scan2CAD removes all Pick Colored speckles, regardless of the background color they are on.

Before	After: Layer Colors = blue and gray
Before	After: Layer Colors = all the colors on the image

If Layer Colors are selected, Scan2CAD removes all Layer Colored speckles, regardless of the background color they are on.
