Circular Progress Meter 2.0 User Control

A circular progress bar/meter usercontrol with the following features:

Solid color, fading colid color, or gradient blend

One-, two- or three-color options

Full-circle or arc of any size from 45 to 359 degrees

Display value as a colored arc, a 'needle', or both

Five styles of 'ticks' around edge, spaced however you want

Display value as number or percentage--any font, color, and position!

Customizable text shadow, too!

Change background colors or use AutoMask to make background transparent

Use custom picture backgrounds and mask pictures for transparency

Show/hide border, change width

Show/hide start line when value is zero

Start at any angle (offset)

Clockwise or Counter-Clockwise movement

Change min/max values

Fully scalable

Also demonstrates various API graphics calls, getting the true color of a system color, use of mask color, using custom Enums for user control properties, scaling pictures and masks, and more.
See screenshot:

Large circle ('78') demonstrates a tricolor gradient, text with shadow, and dot-style ticks

Wide control at top ('64') demonstrates tri-color fade, a 180-degree arc, hollow-dot ticks, needle, inset control border, and the flexibility of text positioning

Large PSI gauge at right demonstrates custom picture & mask picture

'Fuel Gauge' demonstrates custom picture and value as percent

Quarter circle ('53') at lower-left demonstrates 90 degree arc, box ticks, a bi-color fade, counter-clockwise motion, automask (it doesn't overlap the large meter) and custom shadow placement

'Wooden' meter near bottom demonstrates a 140-degree arc, offset angle, and custom picture as full background

Black meter near bottom demonstrates border and line-style ticks with no background, and the effect of a tri-color fade where the start- and midcolors are the same (white) and the end color is different (red)

Pink meter ('42') in center demonstrates the Automask by overlapping it's neighbors, and a tricolor fade where the start and end colors are the same but the midcolor differs.

The reddish meter near the bottom ('65') demonstrates blends using system colors (in this case from ButtonFace to Highlight with ActiveTitleBar color as needle)

Tiny meter inside PSI gauge demonstrates another use of Automask
