Ako zmensim a ulozim obrazok? – PHP – Fórum – Programujte.com

Moze mi niekto pomoct ako zmensim a ulozim obrazok do ineho adresara? Som na to trosku kratky...
Vopred dakujem.

To Karol: teoria je nasledovna:
- zistis typ obrazku (podla pripony alebo exif_imageType() alebo imageSize() ktoru doporucujem)
- ziskas obrazok so suboru (imageCreateFormJpeg(),imageCreateFormPng(),imageCreateFormGif())
- vytvoris novy obrazok (imageCreateTrueColor())
- zmenis velkost (imageCopyResized())
- a ulozis pod inim nazvom (imageJpeg(),imagePng(),imageGif())

pred casom som pisal image resizer toto je jeho jadro snad ti to na neco bude

$thumb=imagecreatetruecolor($new_width,$new_height);

	switch (exif_imagetype($input_image)):

	  case IMAGETYPE_JPEG: echo "Image type: JPEG (JFIF).<br>";

			       $source=imagecreatefromjpeg($input_image);

			       imagecopyresized($thumb,$source,0,0,0,0,$new_width,$new_height,$width,$height);

			       imagejpeg($thumb,$output_image);

			break;

	  case IMAGETYPE_PNG: echo "Image type: PNG.<br>";

			      $source=imagecreatefrompng($input_image);

			      imagealphablending($thumb,false) or die("Blend mode unsupported");

			      imagecopyresized($thumb,$source,0,0,0,0,$new_width,$new_height,$width,$height);

			      imagesavealpha($thumb,true) or die ("Can not save alpha chanel");

			      imagepng($thumb,$output_image);

			break;

	  default: die("Unsupported type of image");

	endswitch;
