PocketBrush User Interface

Realizing complex, graphic oriented applications for the Pocket PC platform requires user interface customization to allow fast access to the most common fuctions despite the limited screen real estate. The PocketBrush User Interface consists of a menubar, a custom toolbar and an optional colorbar. The menu bar consists of the File, Edit, View and Filter and View menus and two buttons. To make it just one click away, we have placed the Undo function directly in the menubar. The second button is the "modifier button". Desktop applications use the Shift and Ctrl key to change function behavior, but most Pocket PCs don't come with a keyboard and even if a Pocket PC has a keyboard, the Shift and Ctrl keys work different on each device. The "modifier button" is a three-state-button (off - plus - minus) which can be used together with the selection tools and the rectangle and ellipse tools. It forces rectangles and ellipses to quadrats and circles and allows you to add or remove areas from the current selection.
Custom image manipulation and filter dialogs appear at the bottom of the screen to use as little screen real estate as possible. To cancel image manipulation and filter operations, all dialogs have cancel buttons in form of a small "x" icon at the top right corner.

PocketBrush Toolbar

The PocketBrush toolbar gives you fast access to most of the tools needed to create and edit images. Grouped tools have a small triangle in the lower right of the head tool for that particular group. Click on a selected head tool that has the triangle icon and the flyout group/menu showing all tools in this particular group appears. The 12 tool groups are grouped together in a toolbar and a stylebar section:

Toolbar

Selection Tools: Rectangle, Lasso, Magic Wand, Polygon
Drawing and Painting Tools: Pen, Brush, Airbrush, Spraycan, Eraser
Geometric Shapes: Line, Rectangle, Rounded Rectangle, Ellipse, Polygon
Filter Brush Tool: Blur, Sharpen, Smudge, Lighter, Darker, Tint, Red Eye Reduction, Healing Brush
Eyedropper
Text Tool

Many of the tools have optional parameters which can be accessed by tapping and holding on the tool's icon. Optional parameters include select tolerance, gradient styles and paint opacity.

Selecting Color

PocketBrush offers multiple ways of selecting colors.

Colorbar

For fast color access one of two permanent colorbars can be activated via the "View" menu.
The colorbar can be placed at all four corners of the screen to reduce the needed screen real estate for portrait or landscape mode. To select a foreground color from the colorbar just tap on the color. To select a background color tap-and-hold on the color.

Color Selector Tool
The Color Selector Tool show the current foreground and background colors.

To change the foreground or background color you can click on the foreground or background color box. This will display the current palette.
The foreground and background can be switched by clicking on the little arrow in the upper right corner of the Color Selector icon. To set the default foreground/background colors click on the small black and white squares icon to the lower left of the Color Selector icon. This will reset the foreground and background color to black and white. Tapping-and-Holding on one of the colors boxes will open a color picker dialog box.

Color Picker Dialog Box
The color picker dialog box allows you to enter colors by RGB values and to select the current palette. PocketBrush comes with 6 predefined swatch like palettes including the Visibone* Color Palette, and an RGB Spectrum palette.

Eyedropper

The Eyedropper tool is used to select a specific color from within the image. Any color the you click on with the Eyedropper will make that the foreground color. Tapping-and-Holding on the image will select the current background color.

Selecting Image Areas

Selecting an area of an image is helpful when you want to change the color of a section of the graphic, apply a filter or gradient to alter the appearance, or copy/clear the selected area. PocketBrush provides an assortment of tools for selecting the portion of the image with which you want to apply image operations: "Select Rectangle" or "Select Ellipse" to select rectangular or elliptical areas, "Select Lasso" to create freehand selections, "Select Magic Wand" for selecting a consistently colored area and "Select Polygon" for freehand selections made up of straight line segments.
The "modifier button" allows you to add or remove areas from the current selection and the "Edit" menu offers options to Select the entire image, inverse the selection and to select similar colored areas.
To unselect everything click on an unselected area of the image or click on the select tool icon again.
The toolbar "background mode" determines if a selection is pasted transparent or not. If the transparent "background mode" is used, pixels in the selection will not be pasted if the pixels match the current background color.
Tip: To fill in an irregularly shaped area with a specific color, select the color as the current background color and choose "Cut" from the edit menu.
