SR.ColorConvertedBitmapExtensionNoSourceProfile

Error message

SR.ColorConvertedBitmapExtensionNoSourceProfile

What it means

ProvideValue requires a source color profile to perform the color conversion. When the extension has an image but no source profile (second argument never supplied), it throws InvalidOperationException (SR.ColorConvertedBitmapExtensionNoSourceProfile).

Solutions

  1. Supply the source profile: {ColorConvertedBitmap image, sourceProfile.icm, destinationProfile.icm}
  2. Set both SourceProfile and DestinationProfile properties explicitly when using property syntax
  3. Keep .icm profile resources in the project and reference them correctly

Example fix

// before
<Image Source="{ColorConvertedBitmap image.jpg, AdobeRGB.icm}" />
// after
<Image Source="{ColorConvertedBitmap image.jpg, sRGB.icm, AdobeRGB.icm}" />
Defensive patterns

Strategy: validation

Validate before calling

if (sourceProfilePath == null || destinationProfilePath == null)
    throw new ArgumentException("Both source and destination profiles are required.");

Type guard

static bool HasProfiles(ColorConvertedBitmapExtension ext) => ext?.SourceProfile != null && ext?.DestinationProfile != null;

Try / catch

try { var bmp = (BitmapSource)ext.ProvideValue(sp); }
catch (InvalidOperationException ex) when (ex.Message.Contains("profile")) { /* supply profiles */ }

Prevention

When it happens

Trigger: Using {ColorConvertedBitmap image} with only one argument, or setting Source but leaving SourceProfile null, then evaluating ProvideValue.

Common situations: Omitting the source profile assuming WPF will infer it; partial edits of XAML that dropped the second argument.
