Tracing Paper

I'm currently celebrating the release "Cato's Hike", my new game to teach children (and adults) basic programming! Please check out and enjoy :)

Tracing Paper is a simple yet elegant universal application for the iPad, iPhone and iPod Touch that helps you practice and improve your drawing and sketching skills by giving you a blank translucent canvas with a clean and simple grid on which you can trace anything you wish as often as you like. I believe it will be great for anyone who enjoys drawing or for kids that just want to play around!

After choosing a photo from your library you can adjust its size and location under the canvas using your fingers to pinch to rotate/zoom and one finger to drag it around, then you just trace and shade whatever you wish using your finger. If you make a mistake simply choose the eraser tool and erase your mistake (also, you can use the eraser creatively to help add details in ways that are different from simply drawing), or if you want more accuracy than an eraser there is undo/redo support for up to 8 actions. For those hard to see details zoom, rotate or pan the canvas in for further detail by simply pinching the canvas or using two fingers and dragging to move! For those details where we want the colors to really pop there is now support for coloring and changing the pencil size to draw larger or smaller details as needed! For those moments where you want to quickly fill a region, there is now flood fill support, just press the bucket tool and click in an enclosed region to fill in.

After you are done, wow the world and save your masterpiece to your Photo Library or share it via Email, Facebook, Twitter, PDF or even copy to the clipboard or use open-with to open it in compatible programs to touch it up!

Tracing Paper features:
• Super-smooth drawing with proprietary OpenGL-based rendering engine
• 2 pencil styles
• Support for tracing any photo from your device’s photo album
• Gallery mode to browse to create/load/edit your traces
• Shading support just like a real pencil, draw over the same area multiple times to shade it darker
• Changing brush size to help draw or shade larger areas
• Zooming, rotating and panning of the image to trace to focus on the details that matter (pinch to zoom/rotate, two fingers to pan)
• Flood Fill
• Undo/redo up to 8 actions
• Saving your creations to your Photo library
• Sending your traces via email, Facebook, Twitter, PDF, Open-with for other programs

I am definitely excited about this project and want to continue improving it as much as possible. I've already added many features based on feedback I've received and I'm always appreciative of new ideas that fit the vision and feel of this app. Please feel free to leave ratings and reviews however you feel and I will do my best to respond with updates!
