# 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.

Thank you for your time and effort.

If you want a script that allows you to save your whole map as an image you can use this one.

http://cacaosoft.web.fc2.com/tkool/script/rgss3/mapshot.html

It requires this script to work.

http://cacaosoft.web.fc2.com/tkool/script/rgss3/save_bitmap.html

Then just press F6 and it will convert the whole map into an image.

Also, if you're going to keep posting "Conversion" request, don't just put a reason, the script and a thanks. Explain what the script does and put screenshots so people will know what they're converting and will be more likely to help you.

Also using the script request template helps a lot towards getting your requests done.
