thx again Chuble_XL it is working very well the black frame is perfect.

The script is working for a specific jpg. I would like it work for any jpg, using the following form.

GPStoPic file1.jpg # for a chosen file
or
GPStoPic for * # for all the files in a specific directory.

Once the program executed it should output append "GPS" in the name of the file.

ex: GPStoPic file1.jpg will output file1GPS.jpg

Actual scipt

Code:

source=source.jpg
target=target.JPG
 
# get the image's size, width=$1, length=$2, you need adjust for your image,
# depand the output format of command identify
set -- $(identify $source |awk 'NR==1{split($3,a,"x"); print a[1],a[2]}')  
I_WIDTH=$1
I_LENGTH=$2
 
function maxwidth()
{
        MAX_WIDTH=0
        while read line
        do
                INFO=$(convert -size 1025x768 xc:lightblue -font times.ttf -pointsize 18 -fill none -undercolor white -annotate +20+100 "$line" -trim info:)
                WIDTH=${INFO##*XC }
                WIDTH=${WIDTH%%x*}
        [ $WIDTH -gt $MAX_WIDTH ] && MAX_WIDTH=$WIDTH
        done
        echo $MAX_WIDTH
}
 
MW=$(jhead $source| grep "GPS " | maxwidth)
let WIDTH=MW+10
HEIGHT=60
 
convert -size ${WIDTH}x${HEIGHT} xc:black plaque.jpg
composite plaque.jpg -geometry +5+$(( $I_LENGTH - $HEIGHT - 5 )) -dissolve 60 $source $target
 
CMD=$(jhead $source |grep "GPS " |awk -v width=$1 -v lngth=$2 -v tfile=$target '
NR==1{Latitude=$0}NR==2{Longitude=$0} NR==3{Altitude=$0}
END{
    printf "convert -pointsize 18 -font times.ttf -fill white "
    printf "-draw \"text 10,%d %c%s%c\" ", lngth-46, 39, Latitude, 39
    printf "-draw \"text 10,%d %c%s%c\" ", lngth-28, 39, Longitude, 39
    printf "-draw \"text 10,%d %c%s%c\" ", lngth-10, 39, Altitude, 39
    printf "%s %s\n", tfile, tfile }')
eval $CMD
#END

Can anybody help

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
