    HEIGHT=${HEIGHT:-0}

    # Compute export area using bc (handles floating-point arithmetic)
    X2=$(echo "$X + $WIDTH" | bc)
    Y2=$(echo "$Y + $HEIGHT" | bc)

    # Export using the calculated area
    inkscape "$INPUT_FILE" --export-area="${X}:${Y}:${X2}:${Y2}" --export-filename="$OUTPUT_FILE"
