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)
- 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.
- Transpose (Similar result to the 90 deg. CCW rotation, but is a mirror image.)
- 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
- Use the profile tool to select the angle. (New image size is the same
as the old image.)
- Invert Pixel Values
- Reverse Pixel Bytes
