Beta bringt HEIF/HEIC-Unterstützung

Paint Net

Primär nutze ich nun schon seit vielen Jahren ein Gerät mit macOS. Allerdings kam in der jüngsten Vergangenheit mit dem CHUWI AeroBook auch wieder ein Windows-Gerät dazu.

Zu den Arbeitsgeräten gehören meist auch einfache Tools und Helferlein, die den Arbeitsalltag erleichtern. Für die einfache Fotobearbeitung hat sich bei mir im Laufe der Zeit IrfanView als Must-have gemausert und sobald es aber “etwas mehr” sein muss, kommt auch gern mal ins Spiel.

Für gibt es nun ein Update zu verzeichnen, welches unter anderem auch HEIC/HEIF-Fotos öffnet. Dieses Dateiformat ist mit den neuesten iPhones bekannt geworden und speichert unter anderem Transparenzen und die letzten Arbeitsschritte in der Bearbeitung, bleibt dabei aber im Schnitt bei selber Qualität und bei fast 50 % weniger Dateigröße als das bekannte JPG-Format.

Das Changelog zur letzten BETA von ist so groß, dass ich es in einen Spoiler packen muss. Solltet ihr die App auch gern mal ansehen wollen, so kann ich euch nur einen Blick in den aktuellen Forumsbeitrag nahe legen. Dort findet ihr die nötigen Informationen und auch die neueste Betaversion von

New: Support for loading HEIF/HEIC images (Windows 10 v1809+ required). Saving is not yet supported.
New: Keyboard shortcuts for changing the current layer. You can see these in the Layers menu with the “Go to …” commands. Alt+PgUp/PgDown will go to the layer above/below, and Ctrl+Alt+PgUp/PgDown will go to the top/bottom layer.

New: PNGs can now be saved as “interlaced”

New: Plugins that use IndirectUI can now use a UriProperty with a LinkLabel control (thanks @null54!)

New: Effect plugins can now more easily make use of the clipboard via the IClipboardService. It will handle all of the tricky clipboard issues such as threading, native data marshaling, and avoiding security vulnerabilities that exist in the standard WinForms and WPF clipboard APIs.

New: FileType plugins can now specify separate lists of extensions for loading and saving

Changed: Image->Resize supports Super Sampling again, and favors this over Fant when using Best Quality. Fant is still available, but is no longer chosen automatically.

Changed: Holding Ctrl when starting to move a selection with the Move Selected Pixels tool will no longer leave behind a copy of the selected area

Improved: When using Edit->Copy, a 32-bit BGRA bitmap in the DIBV5 format is now placed onto the clipboard so that other apps can read the alpha channel.

Improved: When using Edit->Paste, DIBV5’s are now supported if they have an alpha channel. If they don’t, then the regular DIB loader is used which has some heuristics for detecting an incorrectly defined alpha channel and correcting for it.

Improved: When using Edit->Paste, PNG is now the highest priority format. This maximizes the ability to maintain alpha/transparency, but it does mean that images coming from Microsoft Office apps will appear larger than they used to. This is either a bug or a feature of Microsoft Office. For some reason it places PNGs on the clipboard that are 25%+ larger than the DIB/DIBV5 bitmap that it also places on the clipboard (but which don’t have alpha/transparency).

Improved: BMP now supports saving in 32-bit (with alpha!) and 8-bit indexed.

Improved: PNG and JPEG now supports loading and saving of much larger images.
Improved: JPEG now has configuration for subsampling mode (4:4:4, 4:2:2, and 4:2:0). The default is now 4:2:2 instead of the (unconfigurable) 4:2:0 of older versions.
Improved: TIFF now supports saving at 24- and 8-bit color depths.
Improved: TGA images now load about 4x faster (thanks @null54!)
Improved: Added error reporting to the Save Configuration dialog. Instead of just saying “Preview: (error)”, you’ll also get the standard error dialog that includes the exception which can used for troubleshooting.

Improved CPU usage for thumbnail updates (layers and image tabs) in many cases.
Improved performance of saving for file types where “Auto” bit-depth is supported but not the current choice.
Improved temporary memory usage when saving images at 8-bit color depth.
Improved: Slightly increased the size of the Settings dialog to reduce the need for scrolling in a few important situations
Fixed: AltGr should now work correctly with the Text tool. It will not trigger shortcuts like File -> Save All, or Edit -> Paste into New Image. (thanks @Bruce Bowyer-Smyth for the fix!)
Fixed: Mouse cursors now scale appropriately for non-integer UI scales (e.g. 125% or 175%)
Fixed a number of performance issues in the Save Configuration dialog. Especially with large images, it should now be much faster to change options and to click OK/Cancel.
Fixed flickering in Save Configuration dialog when changing options.
Fixed: Optimized rendering engine to remove huge lag spikes (30+ seconds) when zooming or panning very large images (e.g. 32K x 32K pixels).
Fixed: 8-bit TGA images should now load correctly (thanks @null54 for the fix!)

Fixed: Some 32-bit TGA images were showing up as completely transparent due to their use of an obscure alpha channel type (thanks @null54 for the fix!)

Fixed: Simple message boxes can now be closed with the ESC key

Fixed: Some TIFFs could not be resaved as a JPEG due to having too much metadata (usually from Adobe Photoshop). The metadata is now discarded if necessary.

Fixed: Magic Wand now works on very large images (e.g. 65535 x 65535 pixels) without an error.

Fixed: DIBV5 bitmaps should now work with Edit->Paste, which improves alpha channel handling. (thanks @null54 for the fix!)
Fixed: Top-down DIBs should now work correctly with Edit->Paste. (thanks @null54 for the fix!)
Blocked the WebP FileType v1.1.0.0 plugin due to instability. An update is already available.

Blocked the ImAgif FileType v0.12.0.1084 plugin due to incompatibility. An update will hopefully soon be available.
