Description: ------------ Hi. We have a fax server which generates PNG files. I have a scheduled PHP script which converts the PNG files to PDF, saving at least 50% of disk space AND allowing annotations to the faxes for the operators. Sometimes the fax server gets "confused" and doesn't save all the data. Maybe the faxer does something wrong (faxes are coming in from lorry/car mechanics - and sometimes they just get it wrong). The manual says that ... "imagecreatefrompng() returns an empty string on failure. It also outputs an error message, which unfortunately displays as a broken link in a browser." This doesn't seem to be true. I am using the CLI version of PHP to convert the PNGs to PDFs (I've done over 37,000 so far with no problem). Whilst I accept the issue is a corrupt PNG file, the PHP code is not able to fail gracefully and the documentation implies it should. I have uploaded the image in question. I suspect I will have many more of these. I am temporarily removing each one as I find it. The image can be found at http://www.bandvulc.co.uk/PHP Now what IS interesting, is if you open the image in IE with the image toolbar, the image starts to appear and then you get a broken image. If the code doesn't work as is, save the image locally and try changing the URL to the physical file location. I don't know what version of libpng is used or if I can use a different one to test the issue (there is a BIG notice on http://www.libpng.com/pub/png/libpng.html about crashes when reading some sort of PNGs). Regards, Richard Quadling. Reproduce code: --------------- function convertPNG_PDF($sImageLocation) { // Define an array of image resources. $aImages= array(); // Get fax dimensions. $aImageData = getimagesize($sImageLocation); // Get the image. $aImages['Original'] = imagecreatefrompng($sImageLocation); echo "We got here\n"; // Rest of code removed. } $sTestPDF = convertPNG_PDF('http://www.bandvulc.co.uk/PHP/16467.PNG'); echo "We got to here\n"; ?> Expected result: ---------------- We got here We got here and the $aImages['Original'] to contain the image data for further processing.

Ah. No. I DO get an error now though!
