XISFViewer app for iPhone and iPad

XISFViewer allows you to quickly view images in the XISF or FITS formats which are often used for storing scientific images like astronomical photographs and are typically not supported by most image viewer tools. It features the following functions:

* View multiple XISF and FITS images using a familiar Mac OS look and feel.
* Zoom, resize and rotate the images.
* Quickly edit the images.
* View XISF and FITS image metadata.
* Export images in any of the standard Mac OS formats (.png, .jpg, .tif etc.).
* View nonlinear images (e.g., unprocessed camera images) using an automatic screen transfer function.
