gnpplot

Hi,

I noticed that the gnuplot packaged with irap does not support png.

The command set term shows this:

Available terminal types:
canvas HTML Canvas object
cgm Computer Graphics Metafile
context ConTeXt with MetaFun (for PDF documents)
corel EPS format for CorelDRAW
dumb ascii art for anything that prints text
dxf dxf-file for AutoCad (default size 120x80)
eepic EEPIC -- extended LaTeX picture environment
emf Enhanced Metafile format
emtex LaTeX picture environment with emTeX specials
epslatex LaTeX picture environment using graphicx package
fig FIG graphics language for XFIG graphics editor
gpic GPIC -- Produce graphs in groff using the gpic preprocessor
hp2623A HP2623A and maybe others
hp2648 HP2648 and HP2647
hpgl HP7475 and relatives [number of pens] [eject]
imagen Imagen laser printer
latex LaTeX picture environment
mf Metafont plotting standard
mif Frame maker MIF 3.00 format
mp MetaPost plotting standard
pcl5 HP Designjet 750C, HP Laserjet III/IV, etc. (many options)
postscript PostScript graphics, including EPSF embedded files (*.eps)
pslatex LaTeX picture environment with PostScript \specials
pstex plain TeX with PostScript \specials
pstricks LaTeX picture environment with PSTricks macros
qms QMS/QUIC Laser printer (also Talaris 1200 and others)
regis REGIS graphics language
svg W3C Scalable Vector Graphics driver
tek40xx Tektronix 4010 and others; most TEK emulators
tek410x Tektronix 4106, 4107, 4109 and 420X terminals
texdraw LaTeX texdraw environment
tgif TGIF X11 [mode] [x,y] [dashed] ["font" [fontsize]]
tkcanvas Tk/Tcl canvas widget [perltk] [interactive]
tpic TPIC -- LaTeX picture environment with tpic \specials
unknown Unknown terminal type - not a plotting device
vttek VT-like tek40xx terminal emulator
xterm Xterm Tektronix 4014 Mode

This makes it throw an error for some parts of the irap pipeline:
set term png size 2048,768

I'm running Ubuntu 64-bit 14.04 LTS

Thanks,
Jody

Hi @jodyphelan @nunofonseca

on CentOS 7.4, we need to install packages gd-progs and gd-devel to support gnuplot png output.

This issue is solved in the upcoming (devel branch) new version of iRAP. Please reopen if the problem persists in the new version.
Cheers.
