module MiniMagick::Configuration

Attributes

cli[RW]

Set whether you want to use [ImageMagick](www.imagemagick.org) or [GraphicsMagick](www.graphicsmagick.org).

@return [Symbol] `:imagemagick` or `:graphicsmagick`

cli_path[RW]

If you don't have the CLI tools in your PATH, you can set the path to the executables.

@return [String]

debug[RW]

When set to `true`, it outputs each command to STDOUT in their shell version.

@return [Boolean]

logger[RW]

Logger for {#debug}, default is `MiniMagick::Logger.new(STDOUT)`, but you can override it, for example if you want the logs to be written to a file.

@return [Logger]

processor[RW]

@private (for backwards compatibility)

processor_path[RW]

@private (for backwards compatibility)

shell_api[RW]

Instructs MiniMagick how to execute the shell commands. Available APIs are “open3” (default) and “posix-spawn” (requires the “posix-spawn” gem).

@return [String]

timeout[RW]

If you don't want commands to take too long, you can set a timeout (in seconds).

@return [Integer]

validate_on_create[RW]

If set to `true`, it will `identify` every newly created image, and raise `MiniMagick::Invalid` if the image is not valid. Useful for validating user input, although it adds a bit of overhead. Defaults to `true`.

@return [Boolean]

validate_on_write[RW]

If set to `true`, it will `identify` every image that gets written (with {MiniMagick::Image#write}), and raise `MiniMagick::Invalid` if the image is not valid. Useful for validating that processing was sucessful, although it adds a bit of overhead. Defaults to `true`.

@return [Boolean]

whiny[RW]

If set to `false`, it will not raise errors when ImageMagick returns status code different than 0. Defaults to `true`.

@return [Boolean]
