## Globals
Properties listed below affect the entire window, regardless of the profile settings.

| `historySize` | Optional | Integer | `9001` | The number of lines above the ones displayed in the window you can scroll back to. |
| `icon` | Optional | String | | Image file location of the icon used in the profile. Displays within the tab and the dropdown menu. |

## Background Images and Icons
Some Terminal settings allow you to specify custom background images and icons. It is recommended that custom images and icons are stored in system-provided folders and are referred to using the correct [URI Schemes](https://docs.microsoft.com/en-us/windows/uwp/app-resources/uri-schemes). URI Schemes provide a way to reference files independent of their physical paths (which may change in the future).
The most useful URI schemes to remember when customizing background images and icons are:
| URI Scheme | Corresponding Physical Path | Use / description |
| --- | --- | ---|
| `ms-appdata:///Local/` | `%localappdata%\Packages\Microsoft.WindowsTerminal_8wekyb3d8bbwe\LocalState\` | Per-machine files |
| `ms-appdata:///Roaming/` | `%localappdata%\Packages\Microsoft.WindowsTerminal_8wekyb3d8bbwe\RoamingState\` | Common files |
> ⚠ Note: Do not rely on file references using the `ms-appx` URI Scheme (i.e. icons). These files are considered an internal implementation detail and may change name/location or may be omitted in the future.
### Icons
Terminal displays icons for each of your profiles which Terminal generates for any built-in shells - PowerShell Core, PowerShell, and any installed Linux/WSL distros. Each profile refers to a stock icon via the `ms-appx` URI Scheme.
> ⚠ Note: Do not rely on the files referenced by the `ms-appx` URI Scheme - they are considered an internal implementation detail and may change name/location or may be omitted in the future.
You can refer to you own icons if you wish, e.g.:
```json
"icon" : "C:\\Users\\richturn\\OneDrive\\WindowsTerminal\\icon-ubuntu-32.png",
```
> 👉 Tip: Icons should be sized to 32x32px in an appropriate raster image format (e.g. .PNG, .GIF, or .ICO) to avoid having to scale your icons during runtime (causing a noticeable delay and loss of quality.)
### Custom Background Images
You can apply a background image to each of your profiles, allowing you to configure/brand/style each of your profiles independently from one another if you wish.
To do so, specify your preferred `backgroundImage`, position it using `backgroundImageAlignment`, set its opacity with `backgroundImageOpacity`, and/or specify how your image fill the available space using `backgroundImageStretchMode`.
For example:
```json
"backgroundImage": "C:\\Users\\richturn\\OneDrive\\WindowsTerminal\\bg-ubuntu-256.png",
"backgroundImageAlignment": "bottomRight",
"backgroundImageOpacity": 0.1,
"backgroundImageStretchMode": "none"
```
> 👉 Tip: You can easily roam your collection of images and icons across all your machines by storing your icons and images in OneDrive (as shown above).
With these settings, your Terminal's Ubuntu profile would look similar to this:

You can refer to you own icons if you wish, e.g.:
```json
"icon" : "C:\\Users\\richturn\\OneDrive\\WindowsTerminal\\icon-ubuntu-32.png",
```
> 👉 Tip: Icons should be sized to 32x32px in an appropriate raster image format (e.g. .PNG, .GIF, or .ICO) to avoid having to scale your icons during runtime (causing a noticeable delay and loss of quality.)
### Custom Background Images
You can apply a background image to each of your profiles, allowing you to configure/brand/style each of your profiles independently from one another if you wish.
To do so, specify your preferred `backgroundImage`, position it using `backgroundImageAlignment`, set its opacity with `backgroundImageOpacity`, and/or specify how your image fill the available space using `backgroundImageStretchMode`.
For example:
```json
"backgroundImage": "C:\\Users\\richturn\\OneDrive\\WindowsTerminal\\bg-ubuntu-256.png",
"backgroundImageAlignment": "bottomRight",
"backgroundImageOpacity": 0.1,
"backgroundImageStretchMode": "none"
```
> 👉 Tip: You can easily roam your collection of images and icons across all your machines by storing your icons and images in OneDrive (as shown above).
With these settings, your Terminal's Ubuntu profile would look similar to this:
![Custom icon and background image](../images/custom-icon-and-background-image.jpg)
