Dost by pomohlo, pokud byste napsal, jakou _presne_ chybu Vam to
hlasi. Hlasi to "All available frogs were eaten by aligatorz"? Nebo
"Can't locate GD.pm"? Nebo "The data seems very inacurate"?

Dal by pomohlo, pokud byste pouzil nejaky rozumny Subject, ktery by
mel nejlepe neco spolecneho s danymproblemem, takze napriklad s tou
chybou.

A dal s velkou pravdepodobnosti sam dokazete vyzkouset, jestli to tu
samou chybu hlasi, pokud vyhodite ten radek vyse ...

> $im->interlaced('true');

... a tento ...

> # border
> $im->rectangle(0, 0, 759, 419, $black);

... a tento ...

a vsechno ostatni, ktere pravdepodobne s onou chybou nemaji nic
spolecneho, paklize nasleduji az za ni.
