# LosslessJpegTransform Methods
The [LosslessJpegTransform](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Codecs_LosslessJpegTransform.htm.md) type exposes the following members.
## Methods

Aligns given coordinates to the JPEG sample size |
|  | [Close](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Codecs_LosslessJpegTransform_Close.htm.md) | Closes JPEG transform and releases the file opened with [Open(String)](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Codecs_LosslessJpegTransform_Open_1_bb3a7a4f.htm.md) method. |
|  | [Continue](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_SyncHandler_Continue.htm.md) | Resumes execution of the operation previously paused with [Pause()](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_SyncHandler_Pause.htm.md) method.
