# Display flags

A 32-bit integer containing flags that describe how the text should be drawn.

## Overview

The following flags are defined:

- Don’t auto scale: Controls text scaling. If this flag is set to `1`, the text media handler reflows the text instead of scaling when the track is scaled. This flag’s value is `0x0002`.
- Use movie background color: Controls background color. If this flag is set to `1`, the text media handler ignores the background color field in the text sample description and uses the movie’s background color instead. This flag’s value is `0x0008`.
- Scroll in: Controls text scrolling. If this flag is set to `1`, the text media handler scrolls the text until the last of the text is in view. This flag’s value is `0x0020`.
- Scroll out: Controls text scrolling. If this flag is set to `1`, the text media handler scrolls the text until the last of the text is gone. This flag’s value is `0x0040`.
- Horizontal scroll: Controls text scrolling. If this flag is set to `1`, the text media handler scrolls the text horizontally; otherwise, it scrolls the text vertically. This flag’s value is `0x0080`.
- Reverse scroll: Controls text scrolling. If this flag is set to `1`, the text media handler scrolls down (if scrolling vertically) or backward (if scrolling horizontally; note that horizontal scrolling also depends upon text justification). This flag’s value is `0x0100`.
- Continuous scroll: Controls text scrolling. If this flag is set to `1`, the text media handler displays new samples by scrolling out the old ones. This flag’s value is `0x0200`.
- Drop shadow: Controls drop shadow. If this flag is set to `1`, the text media handler displays the text with a drop shadow. This flag’s value is `0x1000`.
- Anti-alias: Controls anti-aliasing. If this flag is set to `1`, the text media handler uses anti-aliasing when drawing text. This flag’s value is `0x2000`.
- Key text: Controls background color. If this flag is set to `1`, the text media handler does not display the background color, so that the text overlay background tracks. This flag’s value is `0x4000`.
