colorFloat

Last eve I was sifting through the Apple App Store looking for a simple utility to quickly convert RGB color values to corresponding float values (RGB integer / 255 = float). I decided to build my own Cocoa application with a few added enhancements.

High-res Image: colorFloat

Run the standard OSX Color Picker and press the second toolBar option (Color Sliders). Select the RGB Sliders option in the popup menu. Notice each RGB value changes as you move through the color spectrum. We can divide each one of the displayed values by 255 to return float values that can be used in source code authoring. In colorFloat the user adds an input RGB value (x3), converts, and appends each conversion result to the desired color channel. The final action displays the corresponding color for confirmation.

I also built in support for what I refer to as Dynamic Floats. Notice the Dynamic Floats HUD located in the high-res image. The Float value strings change dynamically as you move around the color wheel or change the values of the RGB sliders. This feature allows the user to easily sift through the color spectrum to view corresponding floats in real time.

Lastly, I added a simple Palette that consists of five Color Wells. The user can store colors for future access.

The app. turned out pretty well. I found it interesting to take a break from QTKit and explore a few unfamiliar Cocoa Classes.

Notes:

When I find the time I’ll be writing about a bunch of new stuff, mainly Adobe Audition for the Mac, Final Cut Pro X, and a new media playback application that I am finishing up with interesting support for images captured with one of my favorite iPhone apps. – Panascout. Lastly, FiRe 2 … an awesome iPhone audio recorder that supports waveform editing and audio processing.
