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.
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
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
