PDT Editing Demo
Explore Pliable Display Technology in real-time! The PDT Editing Demo was designed to introduce
"detail-in-context" viewing and editing, and to show how the PDT lens can help improve situational
awareness. Within this demo, you will be able to:
See detail without losing contextual surroundings
Configure the PDT lens focal region, base region, magnification level, and the shoulder region on the fly
Move and position the lens in real-time over your area of interest
Explore how PDT can support common tools used to perform tasks such as mark-up, annotation
and editing functions
Unique to PDT is the
(patents pending) algorithm which guarantees that the PDT data displacement
is accurately reversible. With PDT, you have the ability to edit or annotate data within the PDT lens,
and have your changes mapped back to their correct locations in the original unmagnified data set.
How to Use the PDT Editing Demo
Manipulate the Lens
Control the PDT lens with the MDLC (Modular Design Lens Control) handles
and sliders. The lens magnification, position (click and drag), and size can be manipulated with the MDLC
user interface. The PDT lens and cursors for MS Windows are shown in
below. Click on the
illustration to show the cursors for Mac OSX.
Adjust the Size of the Lens
The focal region and base sizes can be changed by clicking and
dragging the handles that surround the focal and base regions.
Fold and Unfold the Lens
Folding the PDT lens allows you to inspect areas of interest in the shoulder of the lens without
repositioning the lens. If data is not clearly visible in the lens shoulder, folding the lens will
extend the shoulder region and make the data easier to view.
To activate folding, make sure the lens is placed upon the image. Go to the Lens drop down menu
and choose the
Turn folding on
option. Position the cursor over the focal region (inner square)
boundary until you see the folding icon appear.
Left click and drag on the focal region boundary to move the focal region with respect to the lens
base. The resultant displacement of the focal region is called
. Click on the
Clear lens folding
option in the Lens drop down menu to remove all lens folding.
Add/Remove the Lens
Click on the Add/Remove button on the toolbar, and view the entire dataset
in an undistorted state. Reapply the lens by clicking on this button again.
Open a New Image
For this demo, IDELIX has supplied you with three example images to choose from.
To change the image you are currently viewing, simply click on the example image button of your choice.
You can also open other images by clicking on the Open File Button located in the toolbar.
Most common image formats are supported such as bmp, gif, jpeg and png.
Pick a Paint Colour
Pick a colour for use in editing by clicking on the Eyedropper button in the
toolbar. Then select a colour from the image by clicking on a pixel with the Eyedropper tool. Alternatively,
you can choose a paint colour with the Colour Dialog Box by clicking on the colour Palette button on the toolbar.
Pixels selected for editing are changed to the current paint colour (see "Edit Your Picture," below).
Edit the Image
Select a pixel, draw a line, or select a rectangular area on the image with the pencil, line-drawing tool, or area-fill tool.
The colour of the selected pixel(s) is automatically changed to the currently-selected paint colour. You can edit pixels anywhere
within the dataset, whether they are located in the PDT lens focal region, on the PDT lens shoulder, or on the unmagnified base plane.
Step back and forward through edits made on the image. These buttons remain inactive until the image has been edited.
