<\/a>P\u0159ed \u010dasem jsem se setkal s probl\u00e9mem jak vyr\u00e1b\u011bt a konvertovat obr\u00e1zky na sv\u00e9m web serveru. Za\u010dal jsem tedy hledat jak to v PHP za\u0159\u00eddit.
\nZe za\u010d\u00e1tku jsem se sna\u017eil pou\u017e\u00edvat klasickou knihovnu GD, kter\u00e1 m\u00e1 p\u0159\u00edmo v PHP podporu v podob\u011b \u0159ady p\u0159\u00edkaz\u016f. GD mi v\u0161ak nevyhov\u011blo v rychlosti a t\u00ed, \u017ee neum\u00ed pracovat s obr\u00e1zky typu GIF. (Jen pro zaj\u00edmavost pokud pou\u017e\u00edv\u00e1te distribuci REDHAT<\/a> jako j\u00e1 a bal\u00edk PHP jste pou\u017eili bez vlastn\u00edho p\u0159elo\u017een\u00ed a m\u00e1te z\u00e1jem pou\u017e\u00edt GD, tak V\u00e1s \u010dek\u00e1 kompilace PHP ze zdroj\u00e1k\u016f. Redhati pou\u017eili pro kompilaci PHP 4.0.1 a vy\u0161\u0161\u00ed switch –with-gd=share, ale bohu\u017eel mi to nefungovalo. Samoz\u0159ejm\u011b mus\u00edte m\u00edt GD nainstalov\u00e1no a pak p\u0159i pou\u017eit\u00ed switche –with-gd=\/usr v\u0161e funguje bez probl\u00e9m\u016f.)<\/p>\n

Ale zp\u011bt k ImageMagick, v\u00fdkon je minim\u00e1ln\u011b dvakr\u00e1t vy\u0161\u0161\u00ed ne\u017e u GD a spolupracuje s v\u00edce jak 60 form\u00e1ty obr\u00e1zk\u016f. D\u00e1le m\u016f\u017eete bez probl\u00e9m\u016f velikost obr\u00e1zk\u016f x * y, ot\u00e1\u010det, dobarvit, ost\u0159it a celou \u0159adu dal\u0161\u00edch zaj\u00edmav\u00fdch funkc\u00ed. Pokud se budete pot\u00fdkat s podobn\u00fdm probl\u00e9mem jako j\u00e1, zkuste se pod\u00edvat, jak by V\u00e1m mohl ImageMagick pomoci.<\/p>\n","protected":false},"excerpt":{"rendered":"
