DFImageManager v0.7.1 Release Notes

Release Date: 2015-09-04 // over 8 years ago

  • Overview

    🐎 DFImageManager 0.7.1 focuses on stability and performance. The main changes were made to the image processing. Images are now decompressed and scaled in a single step (x2-4 times faster depending on scale, significantly reduces memory usage) which allows DFImageManager to scale large images (~6000x4000 px) and prepare them for display with ease.
