[AssetStore] UniPix : Pixel Art Tool (wip)
An article by 
Started re-writing this unfinished UniPix, hopefully first version will be in the asset store soon’ish..(as in this month (January))
AssetStore link: https://www.assetstore.unity3d.com/#!/content/28312?aid=1101lGti
Forum thread: (coming later)
V1.0 Features
– Basic pixel painting
– Floodfill
– Save, Save incremental
– Image panning (up/down/right/left)
– Basic palette (just using texture currently)
– Keyboard shortcuts for common functions (also see Image#2 bottom for more info)
– Preview in real size with different background colors (Image#1 right side of the window )
– Displays MouseCoords & Color under cursor
– Unity Undo / Redo supported
– Image loading (with resize if larger than current canvas)
– Smart Erase (fill erased pixel with neighbor colors or average of them)
– V1.0 price 5usd (with +5usd increments on each update, until ~20-30usd or so(?))
V1.0 Limitations / Known issues
– After saving, window is not updated until mouse is moved
– Only 16×16 or 32×32 texture sizes for drawing canvas
– If you load wrong sized image (for example 32×32 while your canvas is 16×16), it will be resized to canvas by default (you need to create new canvas first and load again if want to match size)
– If palette texture is not set [x] Read/Write enabled, error will appear
– User interface is not nice
TODO / Future plans
– Too many to list.. building this tool mainly for my own use because havent find any good pixel art tool since Microangelo icon editor (discontinued?)
– Better saving system: Save to current image [started]
– WasModified: Display * on window title if image was modified [started]
– Settings tab & Save current settings when closing the window [started]
– Automatic outline & outline color setting [started]
– more to be added..

^v1.0 submitted to asset store
Its alive: http://u3d.as/baZ
*Remember that this is somewhat “early-access” version, quite limited still. (but price will go up in coming updates)
Update submitted to store just now:
v1.1
– Added: Mirrored drawing modes (X, Y)
– Added: Settings Tab
– Added: Automagic Outline & Outline color setting
– Added: “wasModified” boolean, Display * in window title if image was modified (not working in all conditions yet)
– Added: Added “SaveTo” button, to save over the current loadbuffer image file
– Changed: Moved grid color settings to Settings tab
– Changed: UI adjustments
– Known issues: If you do floodfill at the same position twice, error message appears (but it doesn’t break anything..)
– Known issues: If you enable [x] AutoBorder, canvas doesn’t always update automatically (draw/erase something to update it)
this looks useful for creating palettes:
Color Palette Extractor (free)
