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 patented Undisplace 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 Figure 1 below.
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 Folding. 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 Color
Pick a color for use in editing by clicking on the Eyedropper button in the
toolbar. Then select a color from the image by clicking on a pixel with the Eyedropper tool. Alternatively,
you can choose a paint color with the Color Dialog Box by clicking on the color Palette button on the toolbar.
Pixels selected for editing are changed to the current paint color (see Edit the Image, below).
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 color of the selected pixel(s) is automatically changed to the currently-selected paint color. 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.
Play a Pre-recorded Demo
Click on the play demo button to see an autorun demonstration of the Editing Demo in use. To exit the demonstration at any time, simply press Ctrl Esc on your keyboard.
