Issue status update for http://drupal.org/node/18700 Project: Drupal Version: cvs Component: base system Category: bug reports Priority: critical Assigned to: stefan nagtegaal Reported by: stefan nagtegaal Updated by: Dries Status: patch I'm OK with this! I'd like to await James' input though. Dries Previous comments: ------------------------------------------------------------------------ March 10, 2005 - 20:13 : stefan nagtegaal The idea behind the image.gd.inc file is that it should be usable for people who are using GD 1 and GD 2. Unfortunatly, the way it is written now, only support for GD 2 can be given because: Current way of determining GD 2, is not right: if (function_exists('imageCreateTrueColor')) { // GD 2 Handling; } else { // GD 1 Handling } this doesn't work.. imageCreateTrueColor() was already implemented in GD 1, only it failed to work properly.. See these pages: http://www.php.net/imagecratetruecolor#25234 & http://www.php.net/imagecratetruecolor#25487 According to this comments, we should implement this like this: // Silence errors using the @ $image = @imageCreateTrueColor(......); if (!$image) { // GD 1 Handling; } ------------------------------------------------------------------------ March 11, 2005 - 20:03 : stefan nagtegaal Attachment: http://drupal.org/files/issues/image-inc.patch (2.26 KB) Attached patch improves: - the way which deals with the detection of GD 1 or GD 2; - error messages as reported by Steven here: http://drupal.org/node/17645; After applying this to HEAD/Drupal 4.6 RC, we can close the following issues: - http://drupal.org/node/17645; - http://drupal.org/node/13027; Please test/comment and apply attached patch.. ------------------------------------------------------------------------ March 12, 2005 - 10:41 : Dries Isn't the approach taking in http://drupal.org/node/13027 nicer? It doesn't surpress warnings/errors. Maybe that approach doesn't work? ------------------------------------------------------------------------ March 12, 2005 - 10:50 : Bèr Kessels -1 on supressing errors with @. Its ugly, and hardly used in Drupal. We should use our own error handling at all times. ------------------------------------------------------------------------ March 12, 2005 - 11:42 : stefan nagtegaal I will make a new patch, with the more elegant approach you mentioned Dries... ------------------------------------------------------------------------ March 12, 2005 - 19:05 : stefan nagtegaal As noticed before in this issue.. The function imageCreateTrueColor _does_ exist, even in versions of GD before 1.8 only it was broken.. So, function_exist() doesn't work on that the function, because it really _does_ exist, but the fact is that it's simply broken.. So unfortunatly, the more elegant solution doesn't seem to work.. ------------------------------------------------------------------------ March 12, 2005 - 20:01 : pz Stupid question, why not just use the gd_info function? ------------------------------------------------------------------------ March 13, 2005 - 10:54 : Dries What versions of PHP have those old GD toolkits? PHP 4.3.10 comes with GD 2.0.28, it seems, as does PHP 5.0.3. PHP 4.3.3, Drupal's current minimum PHP requirement, comes with GD 2.0.15.
From the looks, we don't need GD 1 handling at all ... (but we might need a global version check). Thoughts?
------------------------------------------------------------------------ March 13, 2005 - 12:32 : stefan nagtegaal PHP 4.1.2 comes with GD 1.62.. The nasty/hackish code with the build-in GD toolkit, is exactly why I proposed to split the image.inc into a separate image.gd1.inc and image.gd2.inc. I would propose a patch which does: - remove all the GD < 2 function calls like imageCreate() and imageCopyResized() and have a real GD 2 compatible image.inc; - introduce a new image.gd1.inc file into Walkahs sandbox; If the module is being moved to the contributions, the image.gd1.inc is also available for people without proper GD 2 support; - more userfriendly and helpfull error reporting for the image-api.. If we agree about this, I'll make patches for inclusion into 4.6.. Which does contain the before mentioned problems with the current usage.. Please, I would like to have some feedback about this... ------------------------------------------------------------------------ March 13, 2005 - 14:55 : stefan nagtegaal Attachment: http://drupal.org/files/issues/image-inc_0.patch (2.99 KB) As proposed above, patch for image.inc.. Please comment or apply... The image.gd1.inc file wil be posted after this post... ------------------------------------------------------------------------ March 13, 2005 - 14:57 : stefan nagtegaal Attachment: http://drupal.org/files/issues/image.gd1.inc (2.07 KB) And the image.gd1.inc file for Walkahs sandbox... Tell me what you all think about this..
