Review comments at @PhotoLocator/ImageTransformCommands.cs:
- Around line 326-334: Guard the zero-mask case in the sourceBitsPerChannel
calculation in the resize Task.Run block, passing a value that lets FloatBitmap
reject unsupported formats instead of throwing DivideByZeroException. Preserve
the existing user-facing unsupported-pixel-format error; do not add support for
indexed formats.
- Around line 60-63: Update the non-JPEG branch in RotateSelectedAsync to
preserve the original item.Orientation and restore it if loading or saving fails
or is canceled; retain the existing successful rotation behavior and propagate
the failure.
Review comments at @PhotoLocator/LocalContrastView.xaml:
- Line 98: Update the BlackPoint checks in AstroStretchOperation.Apply and
LocalContrastViewModel.ApplyAstroStretchOperation to treat any nonzero value,
including negative values, as active. Preserve the existing behavior for zero
and other operation conditions.
Review comments at @PhotoLocator/Metadata/MaskBasedNaming.cs:
- Around line 256-259: Update the slash-tag check in the tag-parsing flow to use
StartsWith('/') instead of indexing tag[0], so an empty tag reaches the existing
Unsupported tag ArgumentException path.
- Around line 122-127: Update the overload of AppendMetadata that accepts query1
and nullable query2 so it skips the second GetQuery call when query2 is null.
Preserve the existing fallback to query2 when query1 returns null and the
current value conversion and append behavior.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
A negative BlackPoint has no effect when BackgroundRemovalSmooth is 0.
The slider now allows values down to -0.01. AstroStretchOperation.Apply (line 41) only applies the black point in the else if (BlackPoint > 0) branch. LocalContrastViewModel.ApplyAstroStretchOperation (line 570) also only runs the operation for BlackPoint > 0. If stretch and background removal are both 0, a negative black point is ignored. IsNoOperation still reports that an operation is set.
Proposed fix
- else if (BlackPoint > 0)
+ else if (BlackPoint != 0)- if (IsAstroModeEnabled && (AstroStretch > 0 || BackgroundRemovalSmooth > 0 || BlackPoint > 0))
+ if (IsAstroModeEnabled && (AstroStretch > 0 || BackgroundRemovalSmooth > 0 || BlackPoint != 0))🤖 Prompt for AI Agents
