IMAGEMAGICK HOSTING SOFTWARE
In general, I support encouraging users to always run the latest versions of software on their servers. The PHP 7.4 container, for example, has ImageMagick 6.9.11-60 Q16 x86_64 and WebP support.Īs far as I am aware, as long as the libwebp package is present when compiling ImageMagick, both version 6 & 7 will be compiled with WebP support. This includes the local Docker environment in trunk used for contributing. I've seen several different setups that have ImageMagick v6 and WebP support included.
All method channel analogs have been removed (e.g.MagickCore, version 7, adds an ExceptionInfo argument to those methods that lacked it in version 6, e.g.Almost all image processing algorithms are now channel aware.The read mask is honored by most image-processing algorithms. Version 7 supports both a read and write mask. ImageMagick version 6 only supports read mask in limited circumstances.To process RGB, set the colorspace to RGB (e.g. Grayscale images consume one pixel channel in ImageMagick version 7.Use GetPixelAlpha() or SetPixelAlpha() to get or set the alpha pixel channel value.We support alpha rather than opacity (0 transparent QuantumRange opaque).All color packet structures, PixelPacket, LongPacket, and DoublePacket, are consolidated to a single color structure, PixelInfo.Use the metacontent channel to associate metacontent with each pixel.Use GetPixelChannels() to advance to the next set of pixel channels.Instead it is now a pixel channel and accessed with the convenience pixel macros GetPixelIndex() and SetPixelIndex(). The index channel for colormapped images is no longer stored in the index channel, previously accessed with GetAuthenticIndexQueue() and GetCacheViewAuthenticIndexQueue().Instead it is now a pixel channel and accessed with the convenience pixel macros GetPixelBlack() and SetPixelBlack(). The black channel for the CMYK colorspace is no longer stored in the index channel, previously accessed with GetAuthenticIndexQueue() and GetCacheViewAuthenticIndexQueue().Use convenience macros to access pixel channels (e.g.red, green, blue, opacity) but as an array of channels (e.g. Pixels are no longer addressed with PixelPacket structure members (e.g.You can disable this feature for resource constrained system such as a cell phone with a slight loss of accuracy for certain algorithms (e.g. Expect more accurate image processing results with higher memory requirements and possible slower processing times.
ImageMagick version 7 enables HDRI by default.Imagick :: getVersion () preg_match ( '/ImageMagick (+\.+\.+)/', $v, $v ) if ( version_compare ( $v, '6.2.8' ) <= 0 )Īnd, here is the comparison between version 6 and version 7:Ĭhanges from ImageMagick version 6 to version 7 are summarized here: => ImageMagick 6.6.0-4 Q16 īut, we should get the version with this example: because for some functionalities, there are some things different. Moreover, a lot of OS have the version 6 by default because version 7 needs to be compiled manually (at least, at this moment). ImageMagick can resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.īut, we recommend using ImageMagick, although the last WordPress versions supports WebP and ImageMagick 6 does not support it. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, WebP, HEIC, SVG, PDF, DPX, EXR and TIFF. WordPress uses ImageMagick to create, edit, compose, or convert digital images.
