.with_cli(cli) ⇒ Object

You might want to execute only certain blocks of processing with a different CLI, because for example that CLI does that particular thing faster. After the block CLI resets to its previous value.

Examples:

MiniMagick.with_cli :graphicsmagick do
  # operations that are better done with GraphicsMagick
end
