Error message

Frame #

What it means

Thrown by Core::frame() when the whole frame stack was scanned but no frame sits at the requested position. Positions are zero-based, so any position < 0 or >= frame count ends here. This is a plain argument/range error, not a driver failure.

Solutions

1. Bounds-check against count($image) before requesting a frame
2. After slicing or removing animation frames, recompute indices from the new count()
3. For percentage-style positions, keep the value as a string like '50%' so the modifier normalizes it for the actual frame count

Example fix

// before: unguarded index
$frame = $image->core()->frame($i);

// after: bounds-checked
$last = $image->count() - 1;
$frame = $image->core()->frame(min(max(0, $i), $last));

$count = $image->count();
if ($i < 0 || $i >= $count) {
    throw new OutOfRangeException("frame {$i} requested, animation has {$count} frames");
}
$frame = $image->core()->frame($i);

function isValidFrameIndex(int $index, ImageInterface $image): bool
{
    return $index >= 0 && $index < $image->count();
}

use Intervention\Image\Exceptions\InvalidArgumentException;

try {
    $frame = $image->core()->frame($i);
} catch (InvalidArgumentException $e) {
    $i = $image->count() - 1; // clamp to last frame
    $frame = $image->core()->frame($i);
}

When it happens

Trigger: Calling $image->core()->frame(10) on a 5-frame GIF; $image->removeAnimation(10) (or a numeric-string position like '80' that normalizes out of range for small animations); PixelColorAnalyzer with ->frame($i) beyond the frame count; first()/last() delegating to frame(0)/frame(count()-1) on an empty core (those rethrow as StateException).

Common situations: Hard-coded frame indices applied to animations of varying length; percentage positions like '90%' on short GIFs where normalizePosition() rounds to count(); off-by-one bugs after sliceAnimation() shrank the animation; loops using <= instead of <.
