I have been trying to execute a command for imagemagick using apache exec,
although I cannot get the command to construct properly. A well formatted SO
question on this is here:
http://stackoverflow.com/questions/20664301/executing-complex-command-with-commons-exec
The command I need to execute is this:
convert -size 140x80 xc:none -fill grey -gravity NorthWest -draw "text 10,10
'Copyright'" -gravity SouthEast -draw "text 5,15 'Copyright'" miff:- |
composite -tile - /Users/latu/Pictures/desert.jpg
/Users/latu/Pictures/desertCP.jpg
This has been tested directly into terminal and works.
With my code the following command is constructed:
convert -size 140x80 xc:none -fill grey -gravity NorthWest -draw "text 10,10
'Copyright" -gravity SouthEast -draw "text 5,15 'Copyright" miff:- | composite
-title - /Users/latu/Pictures/desert.jpg /Users/latu/Pictures/desertCP.jpg
Notice that one quote is missing from “Copyright”. I am using [ .addArgument(
"text 10,10 'Copyright’") ] to construct that part.
Also part of this command is a pipe character, which I believe is not working
correctly as well. [ .addArgument("miff:- |",false);]
This is the output I get in my java application:
convert: non-conforming drawing primitive definition `text 10,10 'Copyright' @
error/draw.c/DrawImage/3178.
convert: non-conforming drawing primitive definition `text 5,15 'Copyright' @
error/draw.c/DrawImage/3178.
convert: unable to open image `- |': No such file or directory @
error/blob.c/OpenBlob/2643.
convert: unable to open image `composite': No such file or directory @
error/blob.c/OpenBlob/2643.
convert: unable to open image `composite': No such file or directory @
error/blob.c/OpenBlob/2643.
convert: no decode delegate for this image format `composite' @
error/constitute.c/ReadImage/555.
convert: unrecognized option `-title' @
error/convert.c/ConvertImageCommand/2984.
Any suggestions on what I need to change in my code for the above command to
work?
