Image View |

### Image View

The Image View displays the sample values of raster datasets such as bands and tie-point grids as an image.

The view uses tiled images and image pyramids, and therefore has a good image display performance and memory usage.
Additionally the view is enhanced with a navigation control which can be used to to pan, zoom and rotate the image.

#### Slider Bar

By default the horizontal and vertical slider bars are disabled for the Image View. You can activate the sliders again in the options dialog in the section Layer Properties.
If the slider bars are visible you have also a small button in the lower right corner of the Image View which zooms to the fill image bounds if you click on it

#### Navigation Control

The navigation control, which is located in the upper left corner of the Image View, can be used to pan, zoom and rotate the image. The visibility of the control is dimmed if the mouse pointer is not located over the and it becomes visible when the mouse gets near the control.
If you rotate the image, you can use the CTRL-Key to change the stepping of the rotation angle from continuous values to a discrete stepping of quarter of 90°.
The left image shows the dimmed version of the control the right one shows the active control with a rotation. You can deactivate the navigation control in the options dialog in the section Layer Properties

#### Multiple Windows of the same band

It is possible to open more than one window of the same band to have several views. This can be done by selecting Open Image View from the context menu of the band name in the Product Tree. The will open a new view and will be numbered according to their appearance:

#### Context Menu

When you right-click the mouse over the Image View a popup menu comes up:

Entries:

- Geometry from WKT... - allows to create a geometry from Well-Known-Text (WKT) format.
- WKT from Geometry... - is only enabled if a geometry is selected. It displays the geometry in Well-Known-Text (WKT) format. It can be used as a parameter for the binning processor or in external tools and applications.
- Export Transect Pixels - exports the pixels of a transect
- Export Mask Pixels - export pixel values of a mask to clipboard or file.
- Export View as Google Earth KMZ - exports the current Image to a KMZ file supported by Google Earth.
- Export View as Image - exports the current image to an image file format (JPEG, PNG, TIFF, BMP)
- Export Colour Palette as File - exports the colour palette as CSV-File.
- Export Colour Legend as Image - exports an image of the colour legend.
- Spatial Subset from View - opens a new product subset dialog, with predefined spatial subset scene by the actual Image View.
- Copy Pixel Info to Clipboard - copies all sample values at the current pixel position, their names and physical units (which you also can see in the pixel view) to the clipboard. This copies information as tabulator-separated text and may therefore be pasted directly into a spreadsheet application (e.g. MS Excel).

#### RGB Image Support

On creating an RGB Image View you are prompted to select or create a RGB-Profile. You have also the possiblity to create new and change existing profiles in the Options Dialog.

Note: The band to be used for each of the channels in the current RGB Image View can be changed at any time in the Colour Manipulation Tool View window.
