module Errors
# Raised when a table is spanned in an impossible way.
#
InvalidTableSpan = Class.new(StandardError)
# This error is raised when a method requiring a current page is called
# without being on a page.
#
NotOnPage = Class.new(StandardError)
# This error is raised when Prawn cannot find a specified font
#
UnknownFont = Class.new(StandardError)
# Raised when Prawn is asked to draw something into a too-small box
#

# Raised if group() is called with a block that is too big to be
# rendered in the current context.
#

# This error is raised when Prawn is being used on a M17N aware VM,
# and the user attempts to add text that isn't compatible with UTF-8
# to their document
#
IncompatibleStringEncoding = Class.new(StandardError)
# This error is raised when Prawn encounters an unknown key in functions
# that accept an options hash. This usually means there is a typo in your
# code or that the option you are trying to use has a different name than
# what you have specified.
#
UnknownOption = Class.new(StandardError)
# this error is raised when a user attempts to embed an image of an unsupported
# type. This can either a completely unsupported format, or a dialect of a
# supported format (ie. some types of PNG)

# This error is raised when a named element has alredy been
# created. For example, in the stamp module, stamps must have
# unique names within a document
NameTaken = Class.new(StandardError)
# This error is raised when a name is not a valid format
InvalidName = Class.new(StandardError)
# This error is raised when an object is attempted to be
# referenced by name, but no such name is associated with an object

# This error is raised when a required option has not been set
RequiredOption = Class.new(StandardError)
# This error is raised when a requested outline item with a given title does not exist
UnknownOutlineTitle = Class.new(StandardError)
# This error is raised when a block is required, but not provided
BlockRequired = Class.new(StandardError)
# This error is rased when a graphics method is called with improper arguments
InvalidGraphicsPath = Class.new(StandardError)
# Raised when unrecognized content is provided for a table cell.
