BUTTON.transparencyColor

[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

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

        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 Internet Explorer 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.

Requirements
