This is a very useful script, and a lot of people could benefit from this.

# Map Saver
# Version 0.1
# Author: Omegas7. Site: http://www.myrpgmaker.com
# Credit: Woratana for PNG Saver script.
# =============================================================================
# Save a whole map into a .png file by taking multiple screenshots and finally
# combining them. Exporting the resulting bitmap to a .png image file using
# Woratana's PNG Saver script.
# =============================================================================
# Instructions:
# Go to Paint or whatever image editing software you want.
# Create a new file, width and height will be the same as your map, but
# multiplied by 32. (If map's width is 20, the image's width will be 640).
# Name the image "Blank", and save it on the System folder of your game.
# Go to your game map, and put the player starting position on the
# bottom left part of the map.
# Now make a new event, autorun, with script call:
# $saver = Map_Saver.new
# Then turn self-switch A ON.
# Go to the event's second page, put as condition self-switch A, then put
# script call:
# $saver.update
# Finally make the second page to be autorun as well.
# Run the game, you will see the map will start scrolling. Let it be.
# At the end the script will start creating the image file, this process
# may take several minutes depending on your map's size.
# Sure, it may take very long, but it saves HOURS if you planned to make
# your map manually, so do not complain ;).
# =============================================================================
# Notes:
# The final result will be an image file located on your game's main folder.
# The image will be exactly what appears on the screen, so if you got a HUD,
# it will appear as well.
# If you notice a problem with the final result, like with tiles etc,
# try activating "weird mode" below.
# If the final result is still not fixed, try to get support.
