Trilithon Protractors History
|
|
What's New in Trilithon Protractors 1.6
|
 |
Rebuilt Protractors to operate on Mac OS Lion and
Mountain Lion.
|
|
|
Added a Check For Updates menu
item to the Protractors Application Menu. You can now check to determine if there are
new versions of Protractors available for download.
|
|
What's New in Trilithon Protractors 1.5
|
|
|
Added a Radian Scale.
|
| |
|
|
The Radian Scale
indicates the manner in which multiples of π move around the periphery of the
circle. In addition to displaying angles in radians and degrees, the Radian scale
shows the principal multiples and sub-multiples of π, and a secondary readout
displays fractions of π. These features constitute a valuable tool
for educators.
|
|
|
The Radian
scale displays its primary unit (radians) and also displays the angle in
degrees, as well as displaying the sine and cosine of the
angle.
|
|
|
|
Added a Compass Rose.
|
| |
|
|
The Compass Rose Scale
displays a traditional compass of thirty-two points, with North indicated by a Fleur-de-Lis, and
East indicated with an Iron Cross. Over and above these whimsical aspects, the
Compass Rose captions illustrate the special vocabulary of maritime navigation.
|
|
|
The Compass Rose
scale displays degrees of bearing (measured from the North point) and also
displays the reciprocal bearing — that is, 180° away from your
principal bearing.
|
|
|
|
Enhanced the Interactive Readouts on all of the
scales
|
| |
|
|
The Degree,
Grad, and Mil scales display their primary units
as in previous versions. All three scales now also display the angle in
radians, and also display the sine and cosine of the
angle.
|
|
|
The Degree
scale displays its primary unit (degrees) in two decimal forms. One
form display degrees to two decimal places. The other form displays
degrees and minutes.
|
|
|
|
Removed the Preferences Panel
|
| |
|
|
The Preferences Panel
has been replaced by menus to provide direct control of background colour and opacity
|
|
|
|
Added a Quick Help window available
via the Help menu
|
|
What's New in Trilithon Protractors 1.1
|
|
|
The Background Colour of the
The Major Tracking Line (the red line)
that follows the location of the mouse now leaves a 'bubble' when the mouse is in the
transparent area inside the Protractor body.
This 'bubble' enables you to 'click through' to the application underneath the Protractor.
|
|
|
Fixed a Mistake where
Protractors did not track the mouse after you 'unhide' the application. It now works correctly.
|
|
Features of Trilithon Protractors 1.0
|
|
|
Three different units of
measurement — degrees (360 gradations per circle),
grads (400 gradations per circle), and
mils (6,400 gradations per circle)
|
|
|
Protractors direction of measurement can be
widdershins (anti-clockwise) or deasil
(clockwise) independently for each protractor unit.
|
|
|
Protractors Zero Point can be set to multiples of 30° and 45° (for the
degrees protractor), multiples of 50 grad (for the grads protractor), and multiples
of 800 mil (for the mils protractor)
|
|
|
Protractors displays a real-time interactive angle display as you move the mouse
|
|
|
Background Colour is selectable
from the Preferences Panel;
Background Colour includes Light Metal and Dark Metal
|
|
|
Move Protractors either via the mouse or via the Arrow Keys
|
|
|
Opacity Control — Protractors can be dimmed down so you can see through them
|
|
|
Dim Out When Moving is an option selectable from
the Preferences Panel, so that you can select whether the protractor turns partially
transparent when it is being moved
|
|
|
Set protractor origin to the current mouse location.
Simply move the mouse to any position on the screen and type ⌘ O
(command O, without clicking the mouse first), and the protractor origin (centre) is placed at the mouse location.
If you ever move the protractor right off the screen, you can get it back using this feature
|
|
|
⌘ C (command C) copies the current mouse coordinates to the clipboard
|
|
|
Protractor Settings are Remembered between sessions; you
turn this feature on and off via the Protractors menu
