Using the Pan viewer
Currently, there are two "viewers". The older one is
"stand-alone", and the newer is a "component" viewer.
The main advantage of the newer one is that you can save and load parameter
settings files (having a ".pan" filename suffix). We'll probably
discontinue the stand-alone version at some point. PhotoShop plugins also
also support panning & zooming described below.
You can use the mouse and keyboard to pan and zoom in the viewer.
First, click inside the image display portion. Then:
![](_themes/pan/kdabull1.gif) | "Drag" to pan (i.e., click and old inside the display area with
the left mouse button. Move the mouse while holding the button down.) |
![](_themes/pan/kdabull1.gif) | Shift-drag vertically to zoom smoothly (have the shift key down while starting to
drag). Up zooms in and down zooms out. |
![](_themes/pan/kdabull1.gif) | If you have a wheel mouse, then use the wheel to zoom in and out
discretely. Roll the wheel forward to double and back to halve the
zoom factor. |
Other tips:
![](_themes/pan/kdabull1.gif) | Some effects respond to mouse movement while the right button is down,
usually to position an effect on an underlying image. |
![](_themes/pan/kdabull1.gif) | Resize the window to increase or decrease view space. Why would you
want to decrease? Because currently, displaying does work per pixel,
even in the blank areas (to figure out that they're blank). |
![](_themes/pan/kdabull1.gif) | Starting with release 2000-12-06, pan effects do anti-aliasing
of non-time-varying images, for
smoother display. While the image is changing continuously, it will render
in only one pass in most cases. For non-animated images, continuous change
happens while adjusting the view or parameters. When the changes stop or
slow enough, display will make several passes, progressively improving the
visible image. In each pass, the ideal image is jittered by a small random
amount, and all passes are averaged. You can adjust the number of passes
and the maximum jitter, via the "settings" dialog from the View menu of
the viewer. |
![](_themes/pan/kdabull1.gif) | To copy a displayed image, use the copy button or Control-C, and then paste into another
program. The image will be re-rendered at a resolution and number of
anti-aliasing passes determined by the Settings dialog under the View
menu. Or use Atl-Printscreen to get the whole window at screen
resolution, including
sliders and border, and paste elsewhere. |
![](_themes/pan/kdabull1.gif) | In the component viewer, you can also create new images with File/New dialog
(or blank sheet icon), in which you select a component (effect). You will
see an image together with its own customized set of sliders, check boxes, etc
for the effect's parameters. Once you have set the controls and pan &
zoom to your liking, save it with File/Save (or floppy disk icon). Later,
you can open the resulting file (which should have a ".pan" suffix) to
restore your image, settings and view. Better yet, send it to someone else
who has the Pan component viewer and the effect you used. |
