# 
# Compatibility
# 
#   Does not load normal resource image files. Easy to implement into any
#   script. 90% chance of full compatibility with SDK.
# 
# 
# Idea
# 
#   Ever made a script, but you need to include several little image files for
#   it to work? This is not necessary anymore! With the Bitmap2Code converter
#   you can simply convert bitmap images into RGSS code. Instead of loading the
#   file into the memory from a file, the bitmap will be generated via code.
# 
# 
# Function
# 
#   This little script allows you to quickly load bitmaps converted to code
#   with the Bitmap2Code.exe converter.
# 
# 
# Features
# 
#   - instead of loading image files, the bitmaps will be generated via code
#   - optimizer recognizes same colors and optimizes generated code if possible
#   - several quality options to simplify code by decreasing the number of
#     colors
#   - easy to use: set up the config file, copy the files, run the converter
#     and just copy paste the generated code into your RGSS Editor
#   - easy to implement into any script: just call RPG::Cache.load_code("NAME")
#     instead of the usual bitmap loading methods
# 
# 
# Example how to load a bitmap:
# 
#   bitmap = RPG::Cache.load_code("NAME")
# 
#   It is highly recommened to NOT use this converter on files with large
#   dimensions. If you do so anyway, please read Troubleshooting if you
#   encounter any problems. Also, read the Bitmap2Code converter readme for
#   further information.
# 
# 
# Troubleshooting
# 
#   - Problem:
#     The converter decreases the quality of my bitmaps.
# 
#   - Solution:
#     Set the [Quantization Type] option in the Config.ini to 0 and lossless
#     conversion will be applied.
# 
#   - Problem:
#     I get the "Script is hanging" error during the conversion.
# 
#   - Solution:
#     This can only happen if you try to convert bitmaps of large dimentions.
#     There is no possibility to avoid this problem. However, you can decrease
#     the [Power] option in the Config.ini, but this will also slow down the
#     conversion. Another solution would be to decrease the quality of the
#     bitmap.
