Witam,
Wpadłem na mały problem zmieniam sobie rozmiar pliku i gdy go wyswietle to ma prawidłowe rozmiary powiedzmy 200x200
<?php
header ("Content-type: image/jpeg"); /*
JPEG / PNG Image Resizer
Parameters (passed via URL):
img = path / url of jpeg or png image file
percent = if this is defined, image is resized by it's
value in percent (i.e. 50 to divide by 50 percent)
w = image width
h = image height
constrain = if this is parameter is passed and w and h are set
to a size value then the size of the resulting image
is constrained by whichever dimension is smaller
Requires the PHP GD Extension
Outputs the resulting image in JPEG Format

}
$im = @ImageCreateFromJPEG ($img) or // Read JPEG Image
$im = @ImageCreateFromPNG ($img) or // or PNG Image
$im = @ImageCreateFromGIF ($img) or // or GIF Image
$im = false; // If image is not JPEG, PNG, or GIF
if (!$im) {
// We get errors from PHP's ImageCreate functions...
// So let's echo back the contents of the actual image.
} else {
// Create the resized image destination
$thumb = @ImageCreateTrueColor ($w, $h);
// Copy from image source, resize it, and paste to image destination
@ImageCopyResampled ($thumb, $im, 0, 0, 0, 0, $w, $h, $sw, $sh);
// Output resized image
@ImageJPEG ($thumb);
}
?>
Jednak po zapisie
<?php
imagejpeg($thumb,$new,100);
?>
zmienia rozmiar na totalnie przypadkowy nie wiem czemu.
Pozdro Łukasz
