# Vx To Xp Char Converter
# Version 1.0
# Author game_guy
#-------------------------------------------------------------------------------
# Intro
# Converts the little vx guys to xp format.
#
# Features
# Converts the 12x8 frame chars (ones with 8 people)
# Converts the 3x4 frame chars (the single person)
#
# Instructions
# Just place character files in the Chars/12x8 folder for 12x8 chars.
# Place files in Chars/3x4 folder for 3x4 chars.
# Then run the game, it'll convert it for you.
#
# Credits
# game_guy ~ for making it
# Fantasist ~ teaching me how to get files from folder, and how to use bitmap to
# png code
# 66rpg ~ for their bitmap to png code

Bitmap to PNG By 轮回者
==============================================================================
对Bitmap对象直接使用
bitmap_obj.make_png(name[, path])
name:保存文件名
path:保存路径
感谢66、夏娜、金圭子的提醒和帮助！
