problem with getimagesize

[linus72982]

I'm stumped.  I think this might have something to do with configuration but I get the following error:

Warning: getimagesize(Resource id #2) [function.getimagesize]: failed to open stream: No such file or directory in D:\Hosting\5589581\html\imgSRC\test.php  on line 5

 

on this code:

 

$singleImgData = array();
$imgSize = array();
$useImg = imagecreatefrompng("genericav.png");
$imgSize = getimagesize($useImg);
	$id = 1;
	$x = 1;
	$y = 1;
	while ($id <= ($imgSize[0] * $imgSize[1]))
		{
			$singleImgData[$id] = imagecolorat($useImg,$x,$y);
			$id++;
				if ($x < $imgSize[0])
					{$x++;}
				else
					{
						$y++;
						$x = 1;
					}
		}
print_r($singleImgData);

 

The picture is in the same directory and all that, not sure what I'm doing wrong or if it is just the config of the server.

 

Excuse the unpolished code, I'm still learning.  Thanks for any help.

I assume something is wrong with the path since it simply cannot find the file.

I don't see how it could be a problem with the path since the create file from png function above it doesn't spit an error.  I've checked and re-checked and triple checked the name and type, spelling, made sure it was in the directory, everything.  It's there, in the same folder as this file, exactly as spelled.  I'm stumped.

If you read the documentation for the getimagesize() function, you will learn that it takes the filename as a parameter. It does not take the image resource produced by the imagecreatefrompng() function.

Worked great, thanks!

 

As a side question, now that it's working, I have a question about the output.  The code I posted above (appended with the fix of course) outputs only 9899 values where it should, by my math, output 10,000 values.  All the empty values are at the end.  The image is 100px X 100px, I get the size in x and y, multiply the two to get the total number of px - why am I 100 pixels short?  Of course it actually prints 10,000 variables, it just stops assigning readable values to the last 100 so that the end looks like

[9900] => [9901] => [9902] => [9903] =>

 

There isn't a column of 0,0 and 0,1 and 0,2, etc that I'm missing is there?  Perhaps 1,0 and 2,0, etc?
