Failed to get frame offset

Error message

Failed to get frame offset

What it means

Thrown by Frame::offsetLeft() when Imagick::getImagePage() raises an ImagickException while reading the page geometry's x coordinate. The page x/y values are the frame's offset within the animation canvas, used when compositing or splitting animated images. The native exception is preserved as previous.

Solutions

1. Inspect $e->getPrevious() for the real Imagick error and fix the underlying wand state or input file.
2. Validate the image decoded cleanly before iterating frames (e.g. check width()/height() succeed).
3. Where only the composite geometry matters, prefer the higher-level animation APIs rather than reading each frame's raw page offset.

Example fix

// before
$left = $frame->offsetLeft(); // may throw on corrupt frame

// after
use Intervention\Image\Exceptions\DriverException;
try {
    $left = $frame->offsetLeft();
} catch (DriverException $e) {
    $left = 0; // treat unreadable metadata as no offset
}

if ($frame->size()->width() < 1) {
    throw new RuntimeException('frame not readable; offsets unavailable');
}

function safeOffsetLeft(\Intervention\Image\Drivers\Imagick\Frame $frame, int $default = 0): int
{
    try {
        return $frame->offsetLeft();
    } catch (\Intervention\Image\Exceptions\DriverException) {
        return $default;
    }
}

use Intervention\Image\Exceptions\DriverException;
try {
    $x = $frame->offsetLeft();
} catch (DriverException $e) {
    $x = 0; // offsets are optional metadata for most compositing flows
}

When it happens

Trigger: Calling offsetLeft() (directly, or via setOffsetTop() which reads the current left offset) on a frame whose Imagick wand is in an error state, was destroyed, or belongs to an image whose decode produced no usable frame. Rare builds of ImageMagick can also fail page queries on malformed GIF headers.

Common situations: GIF split/explode workflows reading every frame's offset; calling setOffsetTop() on the first frame of a freshly decoded but truncated upload; workers that previously mutated the native handle directly and left it inconsistent.
