Resample; Convolution Filters - Meade Autostar Software Manual

function properly. To preclude these problems, the contents of the buffers are destroyed before the
rotation takes place. You should then copy the rotated image into the desired buffer(s). After the
command is complete, the newly rotated image is automatically copied into Buffer A.

Resample

The Resample command changes the actual size of the image. This allows you to make an image larger
or smaller. Unlike Resizing which only affects the display, this command actually manipulates the image
data make it a new size. When you select this command, the following dialog appears:
To change the size of the image, just enter the new dimensions desired. If the Preserve Aspect Ratio
switch is set, Any time you enter either the width or height, the other number will be adjusted to perserve
the aspect of the image. With the switch off, you can maker changes that will alter the aspect ratio of the
final image. When you click on OK, the image will be modified.
Remember, when you reduce the size of the image, information will be lost.

Convolution Filters

The Convolution Filter dialog box displays the kernel values of the current convolution filter and allows
you to select from a list of pre-defined kernels or to enter your own values. See the Appendix for a
description of image convolution.
