Zebra_Image, version 2.2.2 now available

Stefan Gabos — Fri, 31 Aug 2012 14:20:30 +0000

Here’s what’s new in version 2.2.2:

fixed a bug where if there were no disabled PHP functions (through php.ini), the library would always return error code 8; thanks to Jim Li;
filters can now be applied to images; the existing filters are those handled by PHP’s imagefilter function: negate, grayscale, brightness, contrast, colorize, edgedetect, emboss, gaussian blur, selective blur, mean removal, smooth and pixelate; multiple filters can be applied at once for creating custom filters;

In version 2.2 a new property is now available: png_compression, which determines the compression level of PNG files; this value of this property is ignored for PHP versions older than 5.1.2; thanks to Julien for suggesting; another new property is sharpen_images which, when enabled, will instruct the script to apply a “sharpen” filter to the resulting images; can be very useful when creating thumbnails but should be used only when creating thumbnails; the sharpen filter relies on PHP’s imageconvolution function which is available only for PHP version 5.1.0+, and will leave the images unaltered for older versions; new cropping options were added: TOPCENTER, TOPRIGHT, MIDDLELEFT, MIDDLERIGHT, BOTTOMLEFT, BOTTOMCENTER, BOTTOMRIGHT; thanks to flam for suggesting; entire logic behind the resize method was rewritten; a bug was fixed where the script would generate warnings if the chmod function was disabled via PHP configuration options; now it will not generate the warning but instead will set a value for the script’s error property; also, a bug was fixed where if one would resize a transparent image and in the process would convert it to a JPEG (no transparency) and the resize method’s background_color argument was set to -1, the resulted image’s background color would be black; now it is white, as described in the documentation; thanks to Julien for reporting;

Zebra_Image is a compact, lightweight, object-oriented image manipulation library written in and for PHP, that provides methods for performing several types of image manipulation operations. It doesn’t require any external libraries other than the GD2 extension (with which PHP usually comes pre-compiled with).

In this version, a bug was fixed when resizing images having height greater than width, and using the resize() method with only the height argument; thanks to Manuweb2 for reporting.

In version 2.1 a bug where the rotate method was not working correctly on transparent PNG/GIF images was fixed; the overall handling of transparent images was improved; a new method “flip_both” method was added which flips an image both vertically and horizontally; the code for flip_horizontal and flip_vertical methods was rewritten; and a more explicit example was added.

Zebra_Image, version 2.0 now available

Stefan Gabos — Tue, 04 Jan 2011 20:59:37 +0000

In version 2.0 the entire code was audited and improved and most of the method names, method arguments and global properties were changed breaking compatibility with previous versions; in addition, the resize() method was improved and can now resize images to exact width and height and still maintain aspect ratio by making use of the crop() method;
