The base class for all bitmap related classes. This is the base class for the Lpixmap classes and only provides methods that shared the other pixmap related classes. This class should not be used directly, use the Lpixmap or Lxpixmap class instead.

Methods

data_stream, data_stream_reverse_bytes, inspect, load, load_from_file, load_from_file, new, to_s, to_str,

Attributes

[RW]	height
[RW]	name
[RW]	width

Public Class methods

new(name, str=nil, width=nil, height=nil) src

Creates an empty bitmap. If str is provided it will be loaded.

name - the name of the bitmap
str - a binary string containing the bitmap

load_from_file(name, filename) src

Returns a Lpixmap or Lxpixmap object loaded using filename.

Public Instance methods

to_s() src

Returns a string containing the bitmap name and (width, height).

to_str() src

Returns a binary string containing the data loaded from the bitmap.

inspect() src

Alias for to_s.

load(str) src

Loads str as a xpixmap object. This method does not do anything. The other pixmap related classes need to define this.

str - a binary string containing the bitmap

load_from_file(filename) src

Loads the bitmap using the filename.

data_stream() src

Return the bitmap’s content as a binary string.

data_stream_reverse_bytes() src

Returns the bitmap as a binary string with each byte reverses (the mswin32 GUI binding needs this).
