Class: WP_Image_Editor_Imagick  - X-Ref

WordPress Image Editor Class for Image Manipulation through Imagick PHP Module

__destruct()   X-Ref
Imagick object.

test( $args = array()   X-Ref
Checks to see if current environment supports Imagick.

We require Imagick 2.2.0 or greater, based on whether the queryFormats()
method can be called statically.

param: array $args
return: bool
since: 3.5.0

supports_mime_type( $mime_type )   X-Ref
Checks to see if editor supports the mime-type specified.

param: string $mime_type
return: bool
since: 3.5.0

load()   X-Ref
Loads image from $this->file into new Imagick Object.

return: true|WP_Error True if loaded; WP_Error on failure.
since: 3.5.0

set_quality( $quality = null )   X-Ref
Sets Image Compression quality on a 1-100% scale.

param: int $quality Compression Quality. Range: [1,100]
return: true|WP_Error True if set successfully; WP_Error on failure.
since: 3.5.0

update_size( $width = null, $height = null )   X-Ref
Sets or updates current image size.

param: int $width
param: int $height
return: true|WP_Error
since: 3.5.0

resize( $max_w, $max_h, $crop = false )   X-Ref
Resizes current image.

At minimum, either a height or width must be provided.
If one of the two is set to null, the resize will
maintain aspect ratio according to the provided dimension.

param: int|null $max_w Image width.
param: int|null $max_h Image height.
param: bool     $crop
return: true|WP_Error
since: 3.5.0

thumbnail_image( $dst_w, $dst_h, $filter_name = 'FILTER_TRIANGLE', $strip_meta = true )   X-Ref
Efficiently resize the current image

This is a WordPress specific implementation of Imagick::thumbnailImage(),
which resizes an image to given dimensions and removes any associated profiles.

param: int    $dst_w       The destination width.
param: int    $dst_h       The destination height.
param: string $filter_name Optional. The Imagick filter to use when resizing. Default 'FILTER_TRIANGLE'.
param: bool   $strip_meta  Optional. Strip all profiles, excluding color profiles, from the image. Default true.
return: void|WP_Error
since: 4.5.0

multi_resize( $sizes )   X-Ref
Create multiple smaller images from a single source.

Attempts to create all sub-sizes and returns the meta data at the end. This
may result in the server running out of resources. When it fails there may be few
"orphaned" images left over as the meta data is never returned and saved.

As of 5.3.0 the preferred way to do this is with `make_subsize()`. It creates
the new images one at a time and allows for the meta data to be saved after
each new image is created.

param: array $sizes {
return: array An array of resized images' metadata by size.
since: 3.5.0

make_subsize( $size_data )   X-Ref
Create an image sub-size and return the image meta data value for it.

param: array $size_data {
return: array|WP_Error The image data array for inclusion in the `sizes` array in the image meta,
since: 5.3.0

crop( $src_x, $src_y, $src_w, $src_h, $dst_w = null, $dst_h = null, $src_abs = false )   X-Ref
Crops Image.

param: int  $src_x   The start x position to crop from.
param: int  $src_y   The start y position to crop from.
param: int  $src_w   The width to crop.
param: int  $src_h   The height to crop.
param: int  $dst_w   Optional. The destination width.
param: int  $dst_h   Optional. The destination height.
param: bool $src_abs Optional. If the source crop points are absolute.
return: true|WP_Error
since: 3.5.0

rotate( $angle )   X-Ref

param: bool $vert Flip along Vertical Axis
return: true|WP_Error
since: 3.5.0

maybe_exif_rotate()   X-Ref
Check if a JPEG image has EXIF Orientation tag and rotate it if needed.

As ImageMagick copies the EXIF data to the flipped/rotated image, proceed only
if EXIF Orientation can be reset afterwards.

since: 5.3.0
