How ReAspect works
ReAspect is a very straightforward, stand-alone software. Load image, then adjust the few settings until the image looks fine, then save it.
The first setting is the aspect conversion. Here we tell the software the type of conversion we want to perform.
The main task is of course 4:3 to 16:9 conversion. The complimentary 16:9 to 4:3 conversion is here for our convenience because to create 4:3 image from widescreen is a simple no-brainer crop operation.
The second settings is a Stretch/Crop ratio slider. This not only gives you the ability to choose between stretching and cropping the image, but it allows you to smoothly mix these two operations. Adding more cropping will allow for less stretching. (For images where full stretch is too much)
Stretch Settings
The heart of ReAspect is its non-uniform gradual stretching algorithm. The amount of stretch is determined by the Stretch/Crop slider and the algorithm is determined by the Stretch Settings.
First setting is Uniform Stretch. This is a simple image stretching as it is typical in any image editing application.
The rest are various non-uniform and gradual stretching where you can determine which part of image will be stretched. For example for the image of dancer on the top of this page we used Stretch Right Side, which will preserve the left side (with the dancer).
You can manually adjust the split point. For example the Stretch Right Side will gradually start stretching the right side from center of the image. If this is too close to your focus point, you can adjust the Split Point by moving the slider - which will start stretching the image earlier (left of) or later (right of) from the center.
Last setting is the Sharpen. This enables the Unsharp Mask Filter (also known as Gaussian Sharpening).
Output Format
On the left side you can set the output format.
