! 'Hello world' script.
! Author: Francois Tonneau

! In GLE scripts, lines that start with '!' are comments and are ignored by the
! compiler.

! Before trying to draw anything, we must define the width and height of the
! drawing area. Here we define it to be 10-cm wide, 4.5-cm high (GLE understands
! all units to be centimeters):

size 10 4.5

! We define line width to be 0.06 cm and the drawing color to be 'indianred',
! one of the colors known by name to GLE (the full list of names can be found
! in the User Manual):

set lwidth 0.06
set color indianred

! Now we move to a point of absolute coordinates ('amove') x = 1 cm, y = 1 cm
! and we draw a 8-cm wide, 2.2-cm high box. The box will have rounded corners
! with a corner radius of 0.3 cm:

amove 1 1
box 8 2.2 round 0.3

! For drawing text, we choose a sans-serif font ('ss': see the User Manual for
! a list of fonts) and a height of 1 cm. For more precise control over color,
! we specify it in the #RRGGBB format. Finally, we write 'Hello, World!' at
! position x = 2.25 cm, y = 1.75 cm:

set font ss
set hei 1
set color #004e58

amove 2.25 1.75
write "Hello, World!"

! To create a PDF image from this script, save it in a folder of your choice,
! open a command prompt, go to your folder, and type 'gle -d pdf hello.gle'. If
! all goes well, GLE will compile the script into a hello.pdf file that can be
! opened and viewed like any other PDF document.

! The '-d' option is short for '-device' and tells GLE which type of output
! (eps, pdf, ...) you expect from script compilation. Type 'gle -help device'
! at the command prompt to see which output formats are available on your
! system. Type 'gle -help' for information about other GLE options.
