fotoxx quick guide
Use this quick guide to get started with fotoxx. More detailed information follows afterwards.

File menu	File management and other administrative functions.

Trash	Move the current image into the fotoxx trash folder.
Print	Arrange images and text in a layout for printing (see sister application printoxx).

Edit Parameters	Edit parameters affecting how fotoxx does panorama and HDR images. Normally you need only to set "pano lens mm" to match your camera lens (35mm equivalent).
Create Thumbnails	Create thumbnail images to make thumbnail pages display faster. Input topmost image directory to search for image files. Do when fotoxx is installed or when image files are reorganized outside of fotoxx.

Slide Show	Use the entire monitor to show images (no menu or toolbar). Use keyboard keys to navigate: left/right arrows for prev/next image, +/- keys for zoom, L/R keys for rotate 90°, T-key for thumbnail window, Esc key to leave slide show mode.

Edit menu	These functions modify image files.
Select Area	Outline an area for subsequent editing using mouse clicks and drags. If no such area is active, editing functions use the entire image.
Brightness Distribution	Flatten the brightness distribution. Enhances low-contrast areas of the image. Sometimes a fast and easy method to make significant improvements.

Warp	Distort an image by pulling on a location with the mouse. For funny effects.
