Pena / Paint app for iPhone and iPad

Pena is an openGL based Paint Package for iPad.

SUPPORTED DEVICES: iPad 3, 4, iPad Air.

Pena is unlike any other 2D paint system you have ever experienced. Painting with Pena allows you to create nearly infinite styles and Effects.

We HIGHLY recommend reading the Pena User Manual, or viewing the Online Video Tutorials, to get an idea as to how Pena works, before you purchase.

Brief feature list:

* Programmable Brushes - Brushes in Pena consist of Effects that you add to your brush. A brush can have up to 32 Effects, the order and settings of which determine exactly what you are painting. For example, you might combine a 4-color gradient with polka-dots and a spiral pattern and use that as your paint.

* Intelligent Canvas - An advanced feature in Pena lets you setup your canvas to know that it has properties. For example, you could specify that a particular part of the canvas is always tinted blue, regardless of what you are painting on it.

* Powerful Effects - Programmable Brushes and Intelligent Canvas Effects are all openGL Shaders. Pena comes with a healthy selection of Effects separated into into these six categories: Color Sources, Procedural Sources, Color Filters, Spatial Filters, Math and Logic, and Special Effects.

* Textures - Pena lets you work with photos and images from your Photo Album. Effects can use up to five textures simultaneously to create complex and varied paint. Pena can also be used to image process photos and add an infinite amount of effects.

* Brush Properties - Pena comes with round, oval, square, and rectangular brushes. A brush can be sized from a point to larger than the screen. Brushes can be rotated, tapered, and offset. Rotation and tapering can change dynamically over time. An Airbrush is available by using the Airbrush Spatial Shader.

* Text and Masks - Pena lets you create selection masks which lets you specify which parts of the canvas can be painted on, and which can not. Selection masks can also be used to create text using any of the hundreds of built-in iPad fonts.

* Extensive Save and Load - Pena has four independent saving and loading mechanisms. Favorite brushes can be saved and loaded. Favorite brush and surface Effects can be saved and loaded. And finally, all aspects to the current painting can be saved and loaded. Painting aspects can be selected and merged with other paintings.

* Support for the Wacom bluetooth stylus such as the Wacom Intuos Creative Stylus and Jot bluetooth stylus such as the Jot Touch 4. Supports Stylus Pressure and Shortcuts. Only on iPad Mini, iPad 3, 4 and above.
