Transparent and Semi-transparent Images

The image annotations support two types of transparency – binary transparency and transparency by alpha channel.

Binary transparency specifies one color in the image to be transparent. The pixels with this color are displayed as fully transparent, other pixels - as fully opaque. Each image can have only one transparent color. The transparent color can be selected by using ImGearARTImage.Page.Transparency property.

In case of Transparency by alpha-channel, the alpha channel represents transparency information of an image on a per-pixel basis. A value of 100% in the alpha channel gives a fully opaque pixel and 0% provides a fully transparent pixel. Image annotations support alpha channel only for pages with the following color spaces - RGBA32 and RGBPA32 with 8 bits per channel.
