Transparency Cell (Layers Section)
Determines the transparency level for a layer color.
0 - 100
Represents the percentage of transparency. The default is 0% (completely opaque).
Values are rounded to the nearest half percent. A value of 100% is completely transparent. Although a layer that has completely transparent color appears the same on the drawing page as a layer that has no color, it interacts with other objects on the page in the same way as if its transparency were 0%. You can also set this value by using the slider control in the Layer Properties dialog box (on the Home tab, in the Editing group, click Layers, and then click Layer Properties).
To get a reference to the Transparency cell by name from another formula, or from a program by using the CellsU property, use:
Layers.ColorTrans[i] where i = <1>, 2, 3...
To get a reference to the Transparency cell by index from a program, use the CellsSRC property with the following arguments:
visRowLayer + i where i = 0, 1, 2...
