Some key-features of krpano:

• Image Qualtiy - the image-generation-algorithms of the krpano tools and the rendering-algorithms of the krpano viewer are trying to present the images in the best possible image-quality, with high details and sharpness.
• Performance - optimized for fast image-rendering and quick loading while trying to use as few system resources as possible.
• Cross-Device / Cross-Browser support - krpano supports the most common browsers and devices and even provides special solutions for certain device-limitations and workarounds for browser-bugs. Older systems and browser-versions are also very well supported.
• Flexible and Customizable - krpano provides a build-in layout- and scripting-system and also several APIs for external custom solutions. The viewer can be fully customized, there are settings and interfaces for almost everything.
• Supports many Panoramic Images Formats - Spherical, Cubical, Cylindrical, Flat-images, the direct use of Fisheye-images. The images can be tiled and multi-resolution for faster and more efficient loading and memory-management. Videos can be also used as source for the panoramic images.
• Different interactive Viewing Projections (e.g. a Little Planet View) - allows exploring and viewing the panoramic-images in new interesting ways.
• Almost No Limitations, use images as high-resolution as possible and load as many panoramic-images as you want.
• VR Support - build-in and seamless VR-support. Switching to VR is anytime possible, no extra viewer or software is required. Especially also optimized for mobile devices.
• Small file-sizes - even with a lot of functionality there are constant optimizations to keep the file-sizes as small as possible, for faster loading and quicker startups.
• Stable APIs - krpano is designed to be upward-compatible. Content created with older versions should work in the most cases without any changes also in newer versions.
• No external dependencies - all code is developed and maintained in-house.

krpano Tools (Command-Line)
The krpanotools executable is the core tool for processing images (e.g. sphere/cube conversions, resizing and tiling) and for everything related to the license handling.
It can be called from command-line or from batch/script-files or from other applications.
The krpanotools application offers these functions:

• makepano - make a template-based pano or tour.
• maketiles - make or merge tile images. Can be also used for conversion and resizing.
• convert - Convert or resize images.
• makepreview - make a smooth panoramic preview image.
• spheretocube - convert a spherical to a cubical pano image.
• cubetosphere - convert a cubical to a spherical pano image.
• protect - create viewer files with custom protection settings.
• encrypt - encrypt files.
• testserver - the krpano testing server.
• register - license registration tool.

krpano Plugin Interface

krpano provides a small and simple interface for developing own plugins. A plugin can be either a 'code-only' plugin that extends krpano with additional functionality or controls krpano and / or it can be a 'graphical-plugin' which shows or does something on the screen.

There are two types of plugins:

• HTML5 Javascript plugins (.js) for the krpano HTML5 viewer and
• Flash Actionscript3 plugins (.swf) for the krpano Flash viewer.

The basic plugin-to-krpano and krpano-to-plugin interfaces are almost the same for HTML5 and Flash plugins, only system and language specific code is different.

The basic structure is that the plugin has these public functions, which will be called from krpano:

• A registerplugin function - this function will be called from krpano when the plugin will be loaded. The function provides a krpano Interface Object and a krpano Plugin Object.
• An unloadplugin function - when the plugin will be removed from krpano, then this function will be called. Here all elements and events that the plugin has added should be removed.
• And optionally an onresize function to allow the plugin reacting on size changes of the plugin element.

The plugin itself can add custom functions or attributes to krpano just by adding / setting them directly to the krpano object or to the plugin object. For custom attributes that can be set from the xml there is additionally the registerattribute function - it allows adding an attribute with a default value while keeping the value from the xml. And the registerattribute function can be used to add setter/getter attributes - this are attributes which will cause automatically calling a get or set function when accessing the variable - this can be used to get notified when an attribute will been changed.
