BUTTON.transparencyColor

The transparencyColor attribute specifies or retrieves the color that will be transparent in the BUTTON images.

Syntax

elementID.transparencyColor

Possible Values

This attribute is a read/write String with no default containing one of the following values.

Value Description
Auto The color of the pixel at location 0,0 in the image becomes the transparent color.
any IE color format value An Internet Explorer color format value becomes the transparent color (for example, "red" or “#FF0000”).
None No transparency.

Remarks

A transparent color in an image allows whatever is behind the image to show through the transparent areas. The BUTTON will still receive clicks on the transparent region.

The transparent color can be any Internet Explorer color value. If the value of the transparencyColor attribute is set to “Auto”, the color of the pixel at location 0,0 in the image is used.

If the color specified is not one of the valid IE colors, the previous value is maintained.

Because JPGs are lossy and therefore subject to unexpected color change, they are not recommended when transparencyColor is used.
