another imagejpeg question

[Yang Li Ke]

Hi guys,
Im trying to use this code that I found on php.net to create a thumbnail
from an image but it simply displays a black square.
Anyone can tell me what am I doing wrong?

<?

function ImageCopyResamp leBicubic(&$dst , &$src, $dstx, $dsty, $srcx, $srcy,
$w, $h, $zoomX, $zoomY = '') {
if (!$zoomY) $zoomY = $zoomX;
$palsize = ImageColorsTota l($src);
for ($i = 0; $i<$palsize; $i++) {
$colors = ImageColorsForI ndex($src, $i);
ImageColorAlloc ate($dst, $colors['red'], $colors['green'],
$colors['blue']);
}

$zoomX2 = (int)($zoomX/2);
$zoomY2 = (int)($zoomY/2);

$dstX = imagesx($dst);
$dstY = imagesy($dst);
$srcX = imagesx($src);
$srcY = imagesy($src);

for ($j = 0; $j<($h-$dsty); $j++) {
$sY = (int)($j*$zoomY )+$srcy;
$y13 = $sY+$zoomY2;
$dY = $j+$dsty;

if (($sY >= $srcY) or ($dY >= $dstY) or ($y13 >= $srcY)) break 1;

for ($i = 0; $i<($w-$dstx); $i++) {
$sX = (int)($i*$zoomX )+$srcx;
$x34 = $sX+$zoomX2;
$dX = $i+$dstx;

if (($sX >= $srcX) or ($dX >= $dstX) or ($x34 >= $srcX))
break 1;

$c1 = ImageColorsForI ndex($src, ImageColorAt($s rc, $sX,
$y13));
$c2 = ImageColorsForI ndex($src, ImageColorAt($s rc, $sX,
$sY));
$c3 = ImageColorsForI ndex($src, ImageColorAt($s rc, $x34,
$y13));
$c4 = ImageColorsForI ndex($src, ImageColorAt($s rc, $x34,
$sY));

$r = ($c1['red']+$c2['red']+$c3['red']+$c4['red'])/4;
$g = ($c1['green']+$c2['green']+$c3['green']+$c4['green'])/4;
$b = ($c1['blue']+$c2['blue']+$c3['blue']+$c4['blue'])/4;

ImageSetPixel($ dst, $dX, $dY, ImageColorClose st($dst, $r, $g,
$b));
}
}
}
header ("content-type: image/jpeg");
$sourceimg = imagecreatefrom jpeg ("temp.jpg") ;
$destimg = imagecreate (211, 300);
ImageCopyResamp leBicubic($dest img, $sourceimg, 0, 0, 0, 0, 422,600, 211,
300);
imagejpeg ($destimg);
?>

Re: another imagejpeg question

Hi CountScubula,

Thank you very much for always helping me out with my problems.
I tried that imagcopyresized already before I even tried those other
sample codes from php.net but the quality generated from a imagecopyresize d
is really ugly. So this is why im trying to find somethingelse.

Do you have any ideas?

First, your welcome :) (flattery will get you everywhere)

I understand that copyresized is not a resample, but I haven't had many
issues (actauly none) where quality is an issue, is it the resample or
output quality that is buggin you?

try
imagejpeg($im," ",90);

where $im = your source image after copyresized()

I am using copyresized on this site: http://www.hairreview.com (my pet
project), well I am using my gzImage functions.

there is a copyresampled function, I do not know if it is compiled in for
you, but give it a shot.

It's the output quality. the resamble is ok.

See here is an example

http://www.quebecwushu.com/test/test.php

original image is here:

http://www.quebecwushu.com/test/pics/temp.jpg

I used this code:

function thumbnail ($src, $maxv) {
$size = @getimagesize ($src);
if(($size[0] < $maxv)&&($size[1] < $maxv)){
$newx = $size[0];
$newy = $size[1];
}else{
if($size[0] > $size[1]){
$newx = intval ($maxv);
$newy = intval ($size[1] * ($maxv / $size[0]));
}else{
$newy = intval ($maxv);
$newx = intval ($size[0] * ($maxv / $size[1]));
}
}
$destimg = imagecreate ($newx, $newy );
$sourceimg = imagecreatefrom jpeg ($src);
imagecopyresize d ($destimg, $sourceimg, 0,0,0,0, $newx, $newy, $size[0],
$size[1]);
header ("content-type: image/jpeg");
imagejpeg ($destimg,"",10 0);
imagedestroy ($destimg);
imagedestroy ($sourceimg);
}
thumbnail ('pics/temp.jpg', 200);

Re: another imagejpeg question

Sorry, I was able to soften it, but it was ahack so it didnt look so jittery

http://www.gzentools.com/test/resamp.php

<?php

header("Content-type: image/jpeg");

$img = "temp.jpg";

$si = imagecreatefrom jpeg($img);

$ow=485; $oh=335;
$w=200; $h=138;

$da = imagecreate($w, $h);
$db = imagecreate($w, $h);

imagecopyresize d($da,$si,0,0,0 ,0,$w,$h,$ow,$o h);
imagecopyresize d($db,$si,0,0,0 ,0,$w,$h,$ow,$o h);
imagecopymerge( $da,$db,1,1,0,0 ,$w,$h,15);
imagejpeg($da," ",100);

?>

Haven't seen it mentioned yet, so how about the already built in:

http://uk2.php.net/manual/en/function.imagecopyresampled.php

Also you probably want to be using imagecreatetrue color() rather than
imagecreate() if you're working with JPEGs.

(All this needs a recent version of GD, e.g. the one bundled with the last few
versions of PHP)

Re: another imagejpeg question

I know about this function too and it rocks!
but I am worrying if I create a script and distribute it
then people without gd2 will not be able to use this.

Hi Count,

How can the imagecopymerge help for a better quality?

Re: another imagejpeg question

It actualy doesnt, It was a terible hack gone wrong :)

I tried to copy the image over the top of itself, shifted 1 pixel each
direction, and a bit translucent, trying to soften the jerky lines.

Re: another imagejpeg question

take a look at my gzImage script, you will see how I use resampled first,
and if not exist, I used resized.

I use AdSubtract and with it engaged, the individual pages
don't show the correct graphics (except the header pic and
nav bar).

I selected women's short and the page came up with 18 blank
spaces in the table. I clicked on the first one and the
picture shown was a pixelated "Hair Review" squeeze. Strange.
It works fine if I turn AdSubtract off and refresh the page.

Did they provide the various-sized graphics and you're just
resizing them to fit the table? Some have their perspective
squeezed out of proportion a bit, as if a 100x100px pic was
put in the 78x100 box. s12.jpg and s14.jpg are examples.

That's the one I'd opt for.


And I can see why that's your pet site. What a long strange
trip it's been...o132.jpg is a formal 'do'? <g>

Re: another imagejpeg question

Ok several things,

firts, thank you, wow o132.jpg is not a formal hair do. there are over 5,000
images that need to be set up, and I am only about 3,500 into it. I am
viewing the source files and adding them to the site every day. (only 500 or
so, I do have other things I like to do :) When I have them all on the
site, I am going to hire a couple employees to manage it (I will be turning
this into a real print magazine soon) Ther will be move this pic to catagory
boxes for logged in admins.


I am checking the referer to stop image steeling. I am going to be changing
it to a cookie based in the next couple days. I found someone useing
automated software to spider and suck the site.

only the hair review image gets resized to fit the output size, other than
that all images are using the gzImage functions with cache files as well.

I am using a new function in gzImage called Crop, to try an elimate the
sqeeze effect, please let me know if you notice something wrong with that
function (I swear complex stuff no problem, but I stumble everywhere on
simple stuff)
