Thumbnails of some filetypes show in Windows Explorer but XYplorer

[Ampere]

Thanks Horst!!
That app really solved the Thumbails HEIC issue!!

[Horst]

There is one point for Don.

Normaly in Windows 10 or 11 its enough to install the "HEIF Image Extensions" from the Microsoft store.
This allows preview and thumbnails of .heic and .heif files in Explorer and my other file managers.

In XY the preview of .heic works, also MDBU and hover.
Thumbnails are only created for .heif files.
The preview or MDBU for .heif says "Cannot decode"

In the next beta do this:

Code: Select all

previewcheck; //check the currently focused file

It should shed some light on the mysteries.

Gave it a try and here's the results when selecting a .CLIP file using my current ini configuration:

Code: Select all

Preview Check: C:\_DATA\_Sketchbook\page0009.clip

p32 and tf32 seem to work well and fast. Which has the better quality? Compare the results visually:

Code: Select all

preview "C:\_DATA\_Sketchbook\page0009.clip", p32;  //PreviewHandler (32-bit)

Code: Select all

preview "C:\_DATA\_Sketchbook\page0009.clip", tf32; //ThumbnailProvider IShellItemImageFactory (32-bit)

[Display]

They both appear to be the same high quality (1000x1000 px)
ThumbnailProvider IShellItemImageFactory (32-bit) seems to be 100% size.
PreviewHandler (32-bit) appears to be 99% size with a canvas outline border and fills the background with white instead of XY's theme.

Here's a downsampled comparison of what's happening

So I guess tf32 is better!

Some changes in the new beta
.heic files are now ok with Preview, Hover and MDBU

.heif files only the Hover works.
Preview says Cannot decode but sometimes after a long time it displays a preview.
MDBU does nothing

previewcheck; //check the currently focused file
Says the following for a .heif file

Code: Select all

Preview Check: C:\Temp\Test2\Muster\heif  ( picosmos ).heif

Either add heif to Document Files, then p32 will do the job.
Or set PreviewEarlyFactory to anything but 3, then tf32 will do it.

Are you sure that CLIP files get no thumbnails with a fresh instance?

[Horst]

Or set PreviewEarlyFactory to anything but 3, then tf32 will do it.

I now set PreviewEarlyFactory=1
.heic and .heif hover, preview and MDBU work.

There is one problem left, no thumbnails for .heic files.
.heif thumbnails are fine.

I only have the MS HEIF Image Extensions installed.
Previously using the 3rd party CopyTransHEICforWindows tool all was ok in XY.
But I would like to stay with the HEIF Image Extensions as Explorer and other tools
are fine, making preview and thumbnails for both extensions.

[admin]

There is one problem left, no thumbnails for .heic files.
.heif thumbnails are fine.

Assuming that you configured all settings for heic and heif identically, this is weird. Both formats get identical results from previewcheck;?

[jupe]

You need to run this once for heic thumbnails, extlist("thumbs64", "heic", "a"); it isn't required for heif

[Horst]

Here the .heic

This doesn't change anything, still no thumbnails for .heic

[jupe]

Works for me, using the same setup.

edit: Actually, you didn't mention installing the HEVC decoder from the MS Store in addition to the HEIF image extensions, that is also a requirement for heic, and could be why it works for me.
