The imagecolorat() function doesn't work for truecolor images. You will need a an indexed image for this to work. And worse, imagecolorat() actually segfaults when run on a non-indexed image as far as I can tell. Will commit a fix for that shortly. -Rasmus On Thu, 27 Sep 2001, ReDucTor wrote: > Hey, > I couldn't be bothered waiting for someone to show me a host that runs > php with GD, so i am just going to post the code here, and hope that someone > sees it, and checks it out, and shows the results > > If you can't find a jpg file to test this on, just grab the php jpg one, > well i'll post the code now, so people can play with it, remember if you > test it place show the results :D > > btw if you don't understand how to use it, you paste the code into a .php > file, and change imgname to the path of an jpg image, if you want to use an > png image, just change the im to ImageCreateFromPNG, ok, thats all...please > show the results > > <html> > <body bgcolor="#000000"> > <?php > $imgname = "/path/to/a/jpeg/file"; > $im = ImageCreateFromJPEG($imgname); > $output = " "; > for($x=0;$x<imagesx($im);$x++) > { > for($y=0;$y<imagesy($im);$y++) > { > $color = ImageColorsForIndex(ImageColorAt($im, $x, $y)); > echo "<font size=\"1\" color=\"#"; > echo dechex($color['red']); > echo dechex($color['green']); > echo dechex($color['blue']); > echo "\">\$</font>"; > } > echo "<br>\n"; > } > ?> > </body></html> > > - James "ReDucTor" Mitchell > > >
