Scale Katawa Shoujo

# Katawa Shoujo
# Default setting is fullscreen for 1440x900 with black borders at side.
#
# Depends: x11vnc, Xvfb
# vncviewer comes from tightvnc, but you can alternatively use any viewer you want.
#
# To calculate the target resolution and scaler
# that matches your whole screen while maintaining aspect ratio, here's some math:
#
# L  = Longest edge in your resolution, usually Width is more than Height.
# S  = Shortest edge in your resolution, usually Height is less than Width.
# RL = Longest edge of the application's real resolution
# RS = Shortest edge of the application's real resolution
# TW = Target width
# TH = Target height
# scaler = Calculated scaler
#
# scaler = S / RS
# TH     = RS
# TW     = RL + ((L - (RL * scaler)) / scaler)

# NOTE: Renpy throws exceptions on some effects if you run the game in lower resolution than the target.
# In KS's case the target resolution would be 800x640
# There might be more exceptions I'm not aware of so don't rely on this script fully.
#
# So to avoid issues always target resolution >= real resolution

# Resolution is your resolution divided by the scaler, though this might not fill the whole screen.
# If you want to fill whole screen, use the math above.

# If you get ugly scrollbars or otherwise have problems, try adding -geometry <resolution>
# Eg. -geometry 1440x900 for full screen on my resolution in example.
# Alternatively you can use different vnc client.

# Kill
# Kill for GAME_PID doesn't really do anything here. Python probably spawns sub processes.
# Anyways, game gets terminated on XVFB kill.
