The image menu has functions for changing the size, position,
orientation, resolution and data types of images.
For documentation of any of these functions, use the control
key when selecting it.
Scale to Byte
Clip to Byte
Truncate to Byte
Scale to Positive Integer
Clip to Limits Give range of values, output image (or all images if
shift key held down) is clipped to that range. Pixels below the lower
limit are changed to the lower limit, pixels above the upper limit are changed
to the upper limit, pixels in between are not changed.
-
Change to Float
Shrink (Sum)
Duplicate
Reduce data type (This is done automatically before saving an image.
Also this changes the original image, ie. it does not make a new image, as
do the rest of these functions.)
-
Aspect Ratio - Change Width
Aspect Ratio - Change Height
Flip Vertically
Flip Horizontally (Note that this results in an upside down image,
as does the 180 deg. rotation, but that these two inverted images are mirror
reflections of each other.
Translate
Transpose (Similar result to the 90 deg. CCW rotation, but is a mirror image.)
Rotate
90 deg CW and CCW, 180 deg. (New image size is adjusted to retain all
the pixel values)
Type in arbitrary angle, CW or CCW. (New image size is the same as the
old image.)
Use the profile tool to select the angle. (New image size is the same
as the old image.)
