# Export Current Frame

COSEDA provides two frame export actions under the **Tools** menu, both enabled only when a frame is loaded in the viewer.

## Export current frame

**Tools → Export current frame** saves the raw detector data for the current frame as a TIFF file at full bit depth. No display adjustments (gamma, brightness, contrast) are applied — the file contains the same values that the detector recorded.

The bit depth of the output matches the source data:

| Source dtype | Output |
|---|---|
| uint8 | 8-bit grayscale TIFF |
| uint16 | 16-bit grayscale TIFF |
| float32 | 32-bit float TIFF |
| other | cast to float32 TIFF |

A save dialog opens. If you omit the extension, `.tif` is added automatically.

## Export current frame as displayed

**Tools → Export current frame as displayed** saves the frame exactly as it looks in the viewer — with all gamma, brightness, and contrast adjustments applied — as a PNG or JPEG.

If a geometry overlay is active, the exported image includes it. The save dialog lets you choose PNG or JPEG; if you omit the extension it is inferred from the selected filter.

## When to use which

Use **Export current frame** when you need the raw signal values for further processing, or to load the frame in another tool that expects real detector data. Use **Export current frame as displayed** when you want a publication-ready figure or a screenshot that matches what you see on screen.
