| + | Diamond anvil cells have a limited opening and create shadows due to the seat supporting the diamonds. | ||
| + | |||
| + | We we started multigrain crystallography experiments, we though this was going to be a problem and created a script called [[software:remove-shadow|timelessDACShadow]] to do so. | ||
| + | |||
| + | As a matter of fact, this is not very useful as there simply nothing in these regions. You can probably leave the shadows as they are. | ||

| + | ==== Inpainting ==== | ||
| + | |||
| + | By default, the [[software:timelessDiamondSpotRemoval|timelessDiamondSpotRemoval script]] replaces the masked region with the median intensity of the image. Sometimes, this can lead to problems. | ||
| + | |||
| + | In such case, you can use //inpainting// which will try to fill the gap as well as possible. This is done by adding ''--inpaint True'' to the command line arguments. | ||
| + | |||
| + | The script will be significantly slower, but gaps will be filled with values matching the mask's surroundings. As a matter of fact, we have had little use of this option but, at least, it is available. | ||
