The following are instructions on how to run the applets which are part of the HIPR package. These applets are designed to allow the user to try out the operators which are outlined in the worksheets.
You may want to review the general instructions first, which gives a demonstration overview, JAVA details, browser details, known bugs, etc.
Source for this operator.
The only input box is the rotation angle box. Into this is entered an integer that specifies how much the image is to be rotated by. All rotations happen as if the image was a compass point pointing directly North. So if a rotation angle of 90 is entered, then the image will be rotated 90 degrees to the right. The rotations occur about the center of the image.
The output is displayed to the right of the input image.
Pressing the green start button causes the operator to run. Pressing the Stop button causes the operator to stop running. This is useful if the system being run on is very slow and the operator is taking a long time to complete.
The time box shows the amount of time which the operator took to complete the process on the input image.
You can inspect the input and result image pixel values by depressing the left mouse button and moving the cursor over the desired pixel. The pixel coordinates and gray-level value are displayed underneath the image. Note that some images are larger than the displayed 256x256 display window. Larger images are subsampled in an appropriate manner.
You can find out about known problems with the system here.
