1.0.2 update released
26/10/08 14:42 Filed in: Updates
The 1.0.2 update to iSlideRule was
released on October 26, 2008, and should be available for users
within a week. This update contains several new scales, all new
scale graphics that are 1900 pixels wide (1.0.0 and 1.0.1 used
graphics that were 1400 pixels wide). Details of this update are
listed here.
New scales added to this update include:
* CIF and DIF (reciprocals of the CF and DF scales)
* Ln scale (a linear scale giving natural logarithms of numbers from 1 to 10)
* a pair of conversion scales to provide temperature conversions between Celsius and Fahrenheit
* S(mannheim) scale, (used with "A" scale to calculate sines, or the tangents of numbers less than 5.7 degrees
* F(2π) scale, a folded "C" scale, folded at 1 / ( 2π ), useful in electronics calculations
* F(x^4) scale, used with the "C" or "D" scales to calculate fourth powers and roots.
Other features include a new acceleration/deceleration routine when moving the entire slide with the cursor at the left or right margin of the display. The entire slide rule moves left or right more slowly as it moves away from, or towards the ends of the rule.
Another new feature is a way of moving the opposite piece of the slide rule. With an index of either the slide or the bars present in the display, touching that slide, or bar, and not moving the touch, will result in the other piece moving in the opposite direction. Motion is halted either by moving the touch, lifting the finger, or by alignment with the other index position. This motion also has acceleration and deceleration built in, although at this point, neither this motion, nor the other cursor-based motion have "bounce" like the normal movement in the view when moving the slide or the rules by swiping or dragging them.
Minor changes in the app include some settings changes to support the new features, a bit faster launch time, and I've also changed the default launch screen back to a neutral color similar to the initial release. The default image also has some transparency added so that it is easier to know when the application has completed launching and is ready for use.
The other main feature included in this update is compatibility with the first generation iPod Touch devices (I finally got the application tested on one and can now say that it should work fine on that device!)
