208Editing FontsIn the Destination font combo box you can select the font in which to store the blended glyphs. Choose “New font” to put the generated glyphs into a new font.Further down there are two options:Select the second option if you want to blend only glyphs that are selected in the destination font.To the right there are controls to specify the blend amount:Enter the blend percentage in the editing field. If you want to blend fonts nonproportionally along the X and Y axes, uncheck the Uniform check box and enter the blend amount for the two directions.To not let FontLab Studio add nodes to compatible contours leave the Do not interpolate compatible outlines option switched on.Switch on the Remember source and destination fonts option if you have more than one font open and are going to repeat the operation later.Click OK and wait while FontLab Studio blends the fonts. After the process is finished you will find the new glyphs in the new font or in the destination font. The outlines of the two source glyphs will be stored in the Mask layer of each glyph and the blending result in the outline layer.Those glyphs that had compatible outlines and do not get additional nodes during the blend operation will be marked with green color in the font window. Those glyphs that had no their own outlines (composite glyphs) will be marked with blue color.In some cases it is not possible to blend two outlines. This happens when two source glyphs have different numbers of contours, like O and 8. If some glyphs were not blended, FontLab Studio will show a warning message and those glyphs will have an empty outline layer and will be marked with red color.
