Skripta je:

Code:

<?php
$filename = slika;
$width = 100;
$height = 60;

// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
$width = $height*$ratio_orig;
} else {
$height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefrompng($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

// Output
imagejpeg($image_p, null, 100);
?>

Probao sam nekoliko skripti ali isto.

Pokušaj prije "ispisa" slike stavit:
header('Content-Type: image/jpeg'); // jpeg slike
header('Content-Type: image/png'); // png slike
header('Content-Type: image/gif'); // gif slike

Ako ovo ne pomaže, ne znam u čemu je problem.

To jeste bio problem, medjutim kada sam spojio nece da radi cela skripta, prijavi Parse error: syntax error, unexpected $end in \xampp\htdocs\projekat\admin\resize.php on line 210. A nevidim nigde gresku.

Imaš negdje viška/manjka vitičastu zagradu, { ili }.

Nemam vremena tražit, ali ovako na brzinu rekao bi da IF u 18 uvjetu nema zatvorenu zagradu, znači }.

Također, malo mi je čudno što imaš prije switch ELESE bez IF, a u jednom else imaš dvije zatvorene zagrade za redom.

Prijedlog:
if (uvjet)
{
kod za ovaj dio
}
else
{
kod za else
if (uvjet)
{
kod
}
}

i odmah ćeš vidjet što ti i gdje nedostaje.

Da, nisam zatvorio, sinoc sam bio umoran tako da nisam primetio a hteo sam da zavrsim kod. Sada radi ali kada resaizuje jpg ili gif napravi sliku samo u crnoj boji, dok png fajlove lepo resajzuje.

I prijavi "The image "link ka php fajlu" cannot be displayed, becouse it contains errors" kada resajzujem sa jpg i gif extenzijama.

Edit, ako sam dobro skontao mora za svaku extenziju posebno da se stavi $image = imagecreatefromjpeg($filename);.

Dakle za jpg --> imagecreatefromjpeg
za gif --> imagecreatefromgif

Da postavim u if ili postoji neki drugi nacin.

Ovisno o ekstenziji, stavljaš i pripadni header, a ne sve kako si ti napisao. To sam ja kriv, nisam dovoljno precizno napisao.

Probaj ovo, možda riješiš problem.

Inače ne radim previše sa slikama, pa nemam nekih iskustava.

Probaj ovako

IF($file['type'] == ".gif" || $file['type'] == ".jpg" || $file['type'] == ".png" ) {.......

meni dobro rade sve tri extenzije

Re: [Reseno] Image resample nece da radi

Nasao sam skriptu koja radi.

Sada mi treba da naprimer slika koja se napravi odnosno resajzuje dodeli drugi naziv tipa datum-id.jpg

Code:

<?php
$FILENAME='gallery/'.$_FILES['file']['name'].'';
$RESIZEWIDTH=$dimw;
$RESIZEHEIGHT=$dimh;

function ResizeImage($im,$maxwidth,$maxheight,$name){
    $width = imagesx($im);
    $height = imagesy($im);
    if(($maxwidth && $width > $maxwidth) || ($maxheight && $height > $maxheight)){
        if($maxwidth && $width > $maxwidth){
            $widthratio = $maxwidth/$width;
            $RESIZEWIDTH=true;
        }
        if($maxheight && $height > $maxheight){
            $heightratio = $maxheight/$height;
            $RESIZEHEIGHT=true;
        }
        if($RESIZEWIDTH && $RESIZEHEIGHT){
            if($widthratio < $heightratio){
                $ratio = $widthratio;
            }else{
                $ratio = $heightratio;
            }
        }elseif($RESIZEWIDTH){
            $ratio = $widthratio;
        }elseif($RESIZEHEIGHT){
            $ratio = $heightratio;
        }
        $newwidth = $width * $ratio;
        $newheight = $height * $ratio;
        if(function_exists("imagecopyresampled")){
              $newim = imagecreatetruecolor($newwidth, $newheight);
              imagecopyresampled($newim, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
        }else{
            $newim = imagecreate($newwidth, $newheight);
              imagecopyresized($newim, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
        }
        imagejpeg ($newim,$name . ".jpg");
        imagedestroy ($newim);
    }else{
        imagejpeg ($im,$name . ".jpg");
    }
}

if($_FILES['file']['size']){
    if($_FILES['file']['type'] == "image/pjpeg" || $_FILES['file']['type'] == "image/jpeg"){
        $im = imagecreatefromjpeg($FILENAME);
    }elseif($_FILES['file']['type'] == "image/x-png" || $_FILES['file']['type'] == "image/png"){
        $im = imagecreatefrompng($FILENAME);
    }elseif($_FILES['file']['type'] == "image/gif"){
        $im = imagecreatefromgif($FILENAME);
    }
    if($im){
        if(file_exists("$FILENAME.jpg")){

        }
        ResizeImage($im,$RESIZEWIDTH,$RESIZEHEIGHT,$FILENAME);
        imagedestroy ($im);


    }
}
?>

ResizeImage($im,$RESIZEWIDTH,$RESIZEHEIGHT,$FILENAME);

dakle, pozoveš ovu funkciju, staviš koja slika, koja veličina, (širina, visina), naziv slike i to je to.
