ONO::Lib::Image::Magick
Functions
action();
Image actions: rotate, or flip.
Available switches:
-t re-generate thumbs
ONO::Lib::Image::Magick->action( $file, $target, $option, $switches );
returns: 1
convert();
Convert an image, by generating a JPG image in most cases.
Available switches:
-F only convert the First page of a PDF file
-d debug on devstation
-D delete source file after conversion (only if successful)
-h half quality (PDF only, can be combined with -H)
-H quarter quality (PDF only, can be combined with -h)
-Q QR code mode - important, as images need to be converted to RGB
-R force RGB conversion (also see -V)
-S Size force to 920 for HEIC images
-V use the Video library (ffmpeg) instead of Image::Magick for RGB conversion
Important note regarding the handling of PDF documents: In order to read/write PDF files, the IM's policy file may have to bechanged: /etc/ImageMagick-VER/policy.xml
ONO::Lib::Image::Magick->convert( $file, $target, $switches, $option );
detect_convert();
Detect if the convert or magick command is installed. This will prefer the magick command, if available.
ONO::Lib::Image::Magick->detect_convert( );
getinfo();
Return image info, using the Image Magick 'identify' tool.
ONO::Lib::Image::Magick->getinfo( $file, $switches );
returns: $INFO
resize();
Resize an image.
ONO::Lib::Image::Magick->resize( $file, $target, $width, $height, $switches );
returns: ($process,$width,$height,$debugger)
rotate();
Rotate image, using the ImageMagick convert/magick command directly. This can be used as an alternative to the action tool.
ONO::Lib::Image::Magick->rotate( $file, $target, $rotate, $switches );
