Editing multispectral and panchromatic pixels

Mit der Image Analyst-Lizenz verfügbar.

Pixel Editor is used to edit multispectral and panchromatic imagery. The operations that can be applied are limited to obscuring the pixels: Blur Verwischen, Pixelate Verpixeln, Redact Überarbeiten, and Set NoData NoData festlegen.

The Capture group has two tools: Copy Region kopieren and Replace Region ersetzen. Copy allows you to specify an area in the region in which you want to copy the pixels, and then dynamically move and apply it to a different area. Replace allows you to specify a region that you want replaced, and lets you dynamically drag the working region to another area to be used to fill it. Both of these tools work on pixels from the current layer being edited, or you can choose another raster layer to work with in the map by specifying the Source Layer.

Use the Region and Region Mode tools to create a region or edit an existing region. Then choose the operation you want to perform on your selected region. For an example of how to create a region and perform an operation, see Pixelate a confidential region.

The Edit group has an interactive Redact Interaktives Überarbeiten tool and an Operations drop-down gallery. The Redact tool allows you to draw a polygon on the image, and it will black out your region. Each of the Operations will open the Pixel Editor Operations pane, and the operation will only be performed on the selected region. The Pixel Editor Operations pane shows you the parameters available for the edit operation.

Verwischen

Blur

Obscures the selected region with a blurred effect. Blur can also be used to smooth a noisy area.

The Factor option allows you to set the level of blurring to perform, in which higher values result in more blurring.

Check the Sharpen check box to sharpen the image that has been obscured. This will make the region less noticeably obscured.

When the Exclude Region Intersections check box is checked, any regions that intersect the active region will be excluded from this operation.

Verpixeln

Pixelate

Obscures the region by resampling the region to an exaggerated pixel size.

The Factor option allows you to set the level of resampling to perform, in which higher values will create more pixelation.

Check the Sharpen check box to sharpen the image that has been obscured. This will make the region less noticeably obscured.

When the Exclude Region Intersections check box is checked, any regions that intersect the active region will be excluded from this operation.

Überarbeiten

Redact

Black out the selected region.

When the Exclude Region Intersections check box is checked, any regions that intersect the active region will be excluded from this operation.

NoData festlegen

Set NoData

Set the pixels in the selected region as NoData pixels, for each band.

When the Exclude Region Intersections check box is checked, any regions that intersect the active region will be excluded from this operation.

The Undo button Rückgängig can be used to reverse the last action that was performed with the tools on the Pixel Editor tab. Undo can also be performed by pressing Ctrl+Z; this shortcut can also be used to undo actions that were performed within the Pixel Editor Operations pane. The Redo button Wiederherstellen can be used to reverse the undo action that was performed with the tools on the Pixel Editor tab. Redo can also be performed by pressing Ctrl+Y; this shortcut can also be used to redo actions that were performed within the Pixel Editor Operations pane.
