Zooming in and out would result in a lot of slow performance, lag, and even complete hangs of the app for seconds - or more (at 60,000 pixels it could hang for 30-60 seconds or more!). In previous versions you couldn’t really work with very large images, starting around 32,000 x 32,000 pixels. These hold information about what parts of the image need to be rendered and then redrawn on the screen, either because the image has been changed (like with drawings or effects) or because of scrolling and zooming. On the performance side, I’ve rebuilt the data structures inside of the rendering engine that are used for keeping track of invalidation regions. BMP can now save 32-bit images with alpha transparency, while JPEG and PNG can now load and save much larger images, and TIFF now supports saving at 24-bit and 8-bit color depths ("Auto" is also now included). Most of the other built-in file types - BMP, GIF, PNG, JPEG, and TIFF - have been internally upgraded from using GDI+ to being built on top of WIC (Windows Imaging Component). Many newer Android devices also support it. If you want to find some HEIC images, look no further than your recent iPhone (7 or newer). This is necessary due to HEVC being mired in licensing and patent royalty costs.
It’s important to note that HEIC file format support requires two things: 1) you must be using Windows 10 v1809 or newer, and 2) you must install Microsoft’s HEVC Video Extensions from the Microsoft Store which costs $1. You can also download and install it directly from the website. You can get the updater soon by going to ⚙ Settings → Updates → Check Now. You can also force an update check by following these instructions.įor the Classic release, you should be offered the update automatically within the next week or so. If you’re using the Windows Store release, you should get the update automatically within the next 24 hours. Many other quality of life issues have also been addressed or fixed. This is a big update that focus on adding HEIC file format support, fixing performance with very large images, and upgrading and modernizing the functionality of many existing file types (JPEG, PNG, BMP, GIF, and TIFF).
