Lossless rotation
Lossless rotation |

Lossless rotation is a very important new feature of CodedColor. Since JPEG is the standard image format for digital cameras, and since most of your image editing is reduced to simple rotation, this feature ensures that your images will not experience quality loss anymore. You can rotate an image as many times as you wish, without loosing any pixel information. Not all image applications support lossless rotation yet, so make sure to check this before doing any rotations outside of CodedColor. In all other editing cases, you should avoid saving your changes to the original JPEG file, as you will loose quality for every Open / Save combination!To understand more about JPEG compression and quality loss, read this short essay from Bob Johnson, an award winning photopgrapher:JPEG files are by far the most common image format used to display photography on the web and for good reason. The JPEG format does a far better job of retaining color fidelity than the GIF format. Because of the compression scheme used by JPEG, continuous-tone images, such as photos can be a lot smaller than GIFs. It's not uncommon for JPEGs to compress 20:1. Photos stored as GIFs can only compress at or near 5:1. The GIF format does work better for line art and graphics with large single-color areas.
The most important thing to keep in mind is that JPEG is a lossy compression algorithm. That means that every time you save a JPEG, you are losing information in the process. Open a JPEG more than once, tweak something, then resave it and the loss gets even worse. Do it a third, fourth or fifth time, and it gets worse still. The file sizes will still be about the same, but the images will look worse each time.
How do you get out of this vicious cycle? Never open a JPEG, edit it and resave it as a JPEG. Instead, always save your new image in the PSD, TIFF, or other native raw format. After this, you can re-save as a JPEG. The JPEG is your original you say? Before you do anything else, save it in some lossless format (such as PSD or TIFF) and now you can pretend that that file is your original.
