Re: [PHP] libpng error
Thank you very much, really appreciate it. But I have to admit that I an example from
a book in which he creates a gif (and not a png), where he doesn't actually have to
allocate a color. He only has 3 lines which are supposed to work. Maybe true for gif,
but cannot tell, since I don't have gif support.
header("Content-type: image/gif");
$image= imagecreate(200,200)l
imageRectangle($image, 50, 50, 150, 150, $blue);
regards,
thalis

I make change of your code by move some line to correct line and it's
work.
Here this a code
?PHP
header("Content-type: image/png");
$image= imagecreate(200,200) or die("Failed in call to
imagecreate()BR\n");
$blue = imageColorAllocate($image,0,0,255);
imageRectangle($image, 50, 50, 150, 150, $blue);
imagepng($image); // I MOVE THIS LINE
imagedestroy($image);

Hope this will help.

Helloppl,
I have php compiled with GD support (version1.8 so I have png support). I
try the following code and get a broken image:
?php
header("Content-type: image/png");
$image= imagecreate(200,200) or die("Failed in call to
imagecreate()BR\n");
imagepng($image);
$blue = imageColorAllocate($image,0,0,255);
imageRectangle($image, 50, 50, 150, 150, $blue);
imagedestroy($image);
?
I get this error in the Apache error log (Apache with DSO support and php
as a .so):
gd-png: fatal libpng error: Invalid number of colors in palette
gd-png error: setjmp returns error condition
Any ideas what's wrong?
regards,
thalis

Sorry mistake. 3-line code of example was:
header("Content-type: image/gif");
$image= imagecreate(200,200);
imagegif($image);
cheers,

I make change of your code by move some line to correct line and it's
work.
Here this a code
?PHP
header("Content-type: image/png");
$image= imagecreate(200,200) or die("Failed in call to
imagecreate()BR\n");
$blue = imageColorAllocate($image,0,0,255);
imageRectangle($image, 50, 50, 150, 150, $blue);
imagepng($image); // I MOVE THIS LINE
imagedestroy($image);

Re: [PHP] libpng error
Not test your code with GIF yet (I not have GIF support).
In your book they have a result picture of this code ?
I try this by change imagegif($image) to imagepng($image)
and return blank image with specify width.
