    Trim transparent borders without resizing visible content

    • ImageFlow crops to the smallest rectangle containing pixels above the selected transparency threshold.
    • A threshold of 0 removes only fully transparent space; higher values can trim faint antialiased edges.
    • Every result is a PNG. No output is created when the image is fully transparent or has no trimmable border.
