# IIRDS - 0.6.6 beta
# by Ingress Agent VisX (E) - Venezuela
# If you like this please say hi!! on intel COMM
#
# NOTES: IIRDS was made initially for use in my Raspberry Pi and it is very optimized for it
# was tested on Ubuntu and Lubuntu running inside a Virtual Box and is really cool!!
#
#
#Parameters and arguments
# -w width, default $SCREEN_W
# -h height, default $SCREEN_H
# -l (Map link) default $HOMEPAGE (please use quotes)
# -d delay to capture (segs) 
# -e email to send screenshot, empty for NO SEND email
# -t Timelapse, argument is number for minutes. Default $MINUTES=0
# -q Quality of jpg 100 max, recomended for view in smartphone 30, for timelapse >70, best is 100
# 
#

#Set default screen values
#WARNING: Raspberry is slow if these values grow, it works fine 1920x1080, faster 1080x800
SCREEN_W=1920
SCREEN_H=1080
SCREEN_D=16

#Default homepage (param -l)
HOMEPAGE="YOUR-DEFAULT-HOMEPAGE"

#Secs to wait before screenshot
# You must increment this value if SCREEN_W and SCREEN_H grows
DELAYTOCAPTURE=90

#Quality of JPG
JPG_QUALITY=30

#Default minutes for timelapse
MINUTES=0

#Offset to crop (Ninatic and Ingress Intel can change this)
OFFSET_Y=180
OFFSET_X=40
