# Background transparency

Tera Term supports window background transparency. Now Tera Term has two types of transparency function. You can select either function.

## (1) AlphaBlend window

In this type Tera Term window can be background transparency. As a point that should be noted, this function is enabled on only Windows2000 later.
You can configure the value in "Visual" tab on [Setup] Additional settings.
You can set up the value of transparency. The range of transparency is from 0 to 255. The more transparency reduces the value, the more window transparency is blinding. Default value is 255 (opaque).

## (2) Eterm lookfeel window

In this type Tera Term window looks like Eterm background transparency. If this function is enabled, Tera Term window becomes background transparency and mixes the wallpaper with your specified image file(*.jpg).
Please edit the "BGEnable=on" in the teraterm.ini file, or you can configure the value in "Visual" tab on [Setup] Additional settings.

Please refer to "Eterm lookfeel window" for more detailed settings.

## (3) Background image

When both Eterm lookfeel and Background Image is enabled, an image file can be drawn into the terminal background.
And then, the background window does not make transparent.
