It looks like you might be outputting some extra content to the browser,
such as newlines or other content. Use the second parameter of
imagepng() to write the image to a file and compare the size of that
with the bytes sent to the browser (you should be able to get this from
the browsers properties dialogue)
>From the looks of what you've pasted, the extra content is appearing
right after the image data, so perhaps an exit; call right after
imagepng() and seeing if that solves the problem.

[PHP] imagecreate inside an object
hello list,
I'm trying to manage a image resouce inside a method, but
unsuccessfully...
In detail, that's some code snippets:
the class and the method:
class.php
class canvas{
function makeImage($imageWidth = 850){
$im = imagecreate(110, 20) or die("Cannot Initialize new GD
image stream");
$background_color = imagecolorallocate($im, 0, 0, 0);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, "A Simple Text String", $text_color);
return $im;
}
}
... than my test.php file:
header("Content-type: image/png");
include_once("class.php");
$c = new canvas();
imagepng($c->makeImage());
the result in the browser isn't the image itself, but an error that
sounds like: (I traslate the message from italian):
"Image can't be displayed because contains some errors"
but... if I comment out the "header" line, I get this:
‰PNG ��� IHDR���n������V,š ���PLTE���é[an÷���fIDAT•c` `fxÄÀÃ`Ç
ÀçÀä²41ƒ‚€˜Ë–Ý’À...@੤;{á0— œi
...sounds like a png image, isn't it? but It doesn't :-/
The code in the method is very simple, is the same of the php manual
page of "imagecreate" function, and I think the resource is correctly
managed, 'cause if I write this:
$c = new palinsestoCanvas(3);
imagepng(null);
I get: "Warning: imagepng(): supplied argument is not a valid Image
resource"
.. so I think $c->makeImage()) returns successfully the resource.. but I
still didnt see my image..
Any help is appreciated, thanks
Lorenzo
Re: [PHP] imagecreate() question
Did you try making it transparent first, before adding the circle? Only a question because I'm not sure if it will make a difference. I know I had problems trying to get the alpha blending to actually look decent in png's (ended up looking like a very poor gif with a non- antialiased mask) and I think I eventually gave up and put the image on a white background. But that was six months to a year ago and anything more than two weeks out is all but forgotten, old-timers disease I think.

You need to output the png content type header before the call to
imagepng().
If you get a garbled mess the chances are that your script is not
'clean'. In other words, you have output some data elsewhere in your
script. This could be something as simple (and invisible) as a
carriage-return after your closing PHP tag.

RE: [PHP] imagecreate undefined...?
Have you tried dynamically loading the GD functions;
http://us2.php.net/manual/en/function.dl.php
if (!extension_loaded('php_gd')) {
if (strtoupper(substr(PHP_OS, 0, 3) == 'WIN')) {
dl('php_gd.dll');
} else {
dl('gd.so');
}
}
not sure all the names above are correct and you can eliminate a lot of
stuff for Win/Linux installations if you are not targeting both versions.

Sounds very much like you have PHP without the image library compiled
into it. I don't know where to obtain that lib for the Mac, sorry -
but I'm sure someone will.

[PHP] imagecreate undefined...?
I've got this fairly simply script:
// white background and blue text
$bg = imagecolorallocate($im, 255, 255, 255);
$textcolor = imagecolorallocate($im, 0, 0, 255);
// write the string at the top left
imagestring($im, 5, 0, 0, "Hello world!", $textcolor);
// output the image
header("Content-type: image/jpg");
imagejpeg($im);
?>
However, when I run it, I get an error:
Fatal error: Call to undefined function: imagecreate() in [file name] on line 3
I am running under MacOSX 10.3.2 and PHP 4.3.2.
Is there anything I should look for in the phpinfo()?
Any suggestions on how to fix the problem?
Thank you.

Re: [PHP] ImageCreate / ImageCopyResized Path?
You have started a new thread by taking an existing posting and replying to
it while you changed the subject.
That is bad, because it breaks threading. Whenever you reply to a message,
your mail client generates a "References:" header that tells all recipients
which posting(s) your posting refers to. A mail client uses this information
to build a threaded view ("tree view") of the postings.
With your posting style you successfully torpedoed this useful feature; your
posting shows up within an existing thread it has nothing to do with.
Always do a fresh post when you want to start a new thread. To achieve this,
click on "New message" instead of "Reply" within your mail client, and enter
the list address as the recipient. You can save the list address in your
address book for convenience.

[PHP] ImageCreate / ImageCopyResized Path?
Hello everyone! Is it possible to define a path for ImageCreate and/or ImageCopyResize ? I have an image gallery script that uploads images to the server. I would like to automatically create thumbnails of the image [as soon as it is uploaded and saved in a sub-directory. Is this possible with ImageCreate/ImageCopyResize, or the other functions? My directory structure is ../media /images /thumbs/ I have an upload script that upload images to the media/images/ directory. But, I would like to automatically create a thumbnail of the same image, but saved in the media/images/thumbs directory. Is that possible? The final result would like: ../media/images/ |_image1.jpg |_image2.jpg |_thumbs |_thumb-image1.jpg |_thumb-image2.jpg Any suggestions? FYI: I currently have: $thumb = imagecreate ($w, $h); $image = ImageCreateFromJpeg($img); $imagedata = getimagesize($img); imagecopyresized ($thumb, $image, 0, 0, 0, 0, $w, $h, $imagedata[0], $imagedata[1]); imagejpeg($thumb, $img); This works, but it overwrites the original [uploaded] image with the thumbnail. I want to save the thumbnails in another directory. Am I missing something? Please advise. _john -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] imageCreate() error
I'm running PHP 4.3 and W2k with IIS 5.0. I have enabled php_gd and it does show up when I do a phpinfo.

[PHP] Imagecreate and/or GD library not activated
Hello everyone. I wrote a little code creating PNG images under Apache/PHP windows. As the code works fine, I need to transfer it onto the Linux platform. When I execute the code, PHP replies "Fatal error: Call to undefined function: imagecreate()". I had libgd installed. I just added GD 1.8.4. The php.ini file says ";extension=gd.so". I removed the comma, restarted Apache. Does not work. I copied libgd.so in /etc/lib/php4 but did not change anything. Any idea? Thanks.

[PHP] ImageCreate v. ImageCreateTrueColor
Hello, I'm making an Image and I was wondering what the difference is between these two Image constructors. I need to find a way to make dotted and dashed lines (according to different patterns I've been given) and I want the sections between the dots to be transparent. I'm planning on using the ImageSetStyle function. From what I read on PHP.net, some things cannot be used with ImageCreateTrueColor, but it looks like some can only be used that one. One thing I'm interested in is the constant IMG_COLOR_TRANSPARENT - can this be used with ImageCreate? Is there a reason I should use one of the constructors over the other?

RE: [PHP] imagecreate with Windows .exe installer
You need to have that dll installed on your system. You need to download php-version.zip file that contains all of the dlls in it to run with.
