# Mega pixel image rendering library for iOS6 Safari

|
|
||
|
|
Fixes iOS6 Safari's image file rendering issue for large size image (over mega-pixel), which causes unexpected subsampling when drawing it in canvas.
|
||
|
|
By using this library, you can safely render the image with proper stretching.
|
||
|
