--------------------------------------------------
CHANGELOG:
1.2.10
29 October 2006
- print_thumbnail has a new optional argument: display_inline. Refer to documentation for an explanation.
- Corrected filename header print_thumbnail sends to browser. (Used to send filenames without the period between filename and extensions)
- Removed redundant transform method and uses realpath() instead.
26 November 2006
- Added new configuration: remote_check (Refer to Documentation for details)
10 October 2007
Not really any changes. I'm releasing the changes I made after almost a year. There is currently no plan to continue development except to fix some bugs. Current planned and unimplemented features are:
- GIF Transparency Support
- GIF Animationn Support
These will probably stay unsupported unless there is sufficient demand and I find out how to implement them.
1.2.9
26 October 2006
- Changed author's email address
- Added new method of retrieving remote images
==> This method uses the HTTP Retriever class (http://www.phpclasses.org/browse/package/3105.html)
- Example.php will now automatically "require" the file "class_HTTPRetriever.php" if it finds it in the same directory.
- retrieve_remote_file() now supports an optional parameter to "force" it to use a certain method of image retrival
- print_thumbnail() now redirects to an absolute URL instead of a relative URL
- Revamped Error Handling
- output_error() has been superseded by set_error()
- You can now set log_error on to log errors in cache folder
- Script will now terminate only on Fatal Errors
- error_array has been sub-divided into fatal errors and warnings
- Warnings are now logged in error_array.
- Parameter changes to error()
- Behavioural changes to isError() and error() - error() now returns ALL errors
- Intermediate methods will now generate warnings instead of simply returning a "false" for easier debugging.
- Documentation rewritten
28 October 2006
- Fixed bug in example where parent constructor methods was not run
- Added new configuration to clear cache on thumbnail generation complete
- Fixed variable mistake in print_thumbnail where $cached was used instead of $outputted
- Thumbnail Generator web interface added (generator.php)
- PHP Version requirements changed to 4.3.2. Please contact me if the class breaks in any PHP version above 4.3.2.
- print_thumbnail now uses imagecopyresampled() instead of imagecopyresized() (Clear your cache if you want clearer thumbnails for cached ones!)
- print_thumbnail now correctly saves PNG alpha channels
1.2.8
(1/4/2006) - Not an April Fool's changelog!
- print_thumbnail method overhauled to be more efficient
- All methods should return a false on error now. The values public methods return are based on the error_mode setting.
- Overhauled example. Example should work with E_ALL error reporting and with register_globals off.
- Example no longer includes example to output text - this method was intended for internal error output anyway and it seems useless to include in a thumbnail generation class anyway.
- Deprecated method validate_connectivity has been removed.
- Increased the "randomness" for retrieve_image_data temporary filename generation. (i.e. Uses mt_rand() instead of rand())
- retrieve_image_data will no longer overwrite an exisiting file. It will randomly generate filenames until the filename corresponds to a non-existent file.
- Pretty phpDoc generated documentation has returned.
- print_thumbnail now checks for supported file formats.
- A new member, file_ext, was added.
- New format XBM is added. This format is experimental as the PHP manual does not have proper documentation for its function.
1.2.7
(11/10/2005)
- is_remote no longer test for connectivity.
- test_connectivity is now deprecated.
- When retrieving remote files via CURL, CURL will now follow redirects.
- Fixed a bug where if allow_url_fopen is disabled and PHP 5 is avaliable, remote files and in some cases local files that are valid will be deemed invalid.
1.2.6 (30/9/2005)
- Changed versioning system
- scale_thumbnail now allow floats for magnitude
- Changed the behaviour of scale_thumbnail when analysing magnitude values. Negative values are now abs'd. Specify a value smaller than 1 to make the image smaller.
- Replaced all instances of file_get_contents($var) with join(file($var)) to ensure compatibility
- Changed all hashing functions to use sha1 instead of md5. Please remember to clear your cache for this change!
- Cache now supports multiple dimensions for an image file. (i.e. When deciding files to delete, if the file hash is the same, the file will not be deleted)
- Methods will not fail if allow_url_fopen is disabled and will use a workaround
- Uses CURL for remote files if standard fopen functions don't work
- Replaced method's usage of GetImageSize to an internal method that will use a fallback should the standard procedure fail
- Temporary files will be created and destroyed if allow_url_fopen is disabled.
- New Methods: retrieve_image_data and retrieve_remote_file
1.2.5 (5/9/2005)
- Added new error mode to end script execution with a die() statement instead of outputting an image.
- New Method: image_to_file() for lazy people, I mean, to save scripters the trouble of coding a write to file function.
- Updated the example code to include the use of the new method.
- Pretty documentation removed. Please refer to the code's comments from now on.
1.2.4c
- Bug fix: A new cache file is created for the same image when the contents of the image is changed.
1.2.4b
- Fixed a small bug in which the script will not update a remote file cache even when the remote file has changed
This is due to an error in variable usage when generating the MD5 Hash
1.2.4a
- Fixed a ratio calculation error in fit_thumbnail
- fit_thumbnail will no longer enlarge an image
- Better Image Type Handling
== For unsupported formats (like GIF), the class will attempt to output them as PNG.
- Class is now E_NOTICE Safe. Thanks to Carlos Lorenzetti (kcholoren AT hotmail DOT com)
- Added new Method isError to check whether there is an error.
1.2.4
- Added support for scaling (New Method for scaling)
- Added Support for fitting (New Method) (Not perfect yet, uses a rather complicated Logical structures)
- Added Support for Remote Images
- Improved better Error Handling
== Now you can specify whether to terminaate script execution when an error occurs or to record it to an error
== The Error Message can be retrieved using the method error()
== Functions will return false when an error occurs.
- Image types are now auto-dectected
- New Internal Method (is_cacheable)
1.2.3
- Added A New Method (Output Text)
- Script will not display an error instead of returning an image if cache is not enabled
1.2.2 (25/6/04)
- Converted it into a class
- Removed Plock Support (internal use)
NOTE: Prior to version 1.2.2, this script was only used on my website.
