I use ImageMagick with Ghostscript.
I have utility method that I do this, and actually run it on the
server so I only have to install it there rather than on every single
client machine:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
$srcPict:=$1
$width:=$2
$height:=$3
$fileExtension:=$4
//--------------------- save the picture to a temporary file
---------------------
$srcFile:=Temporary folder+"tempPictFile."+$fileExtension
$dstFile:=Temporary folder+"tempPictFile_thumb.png"
WRITE PICTURE FILE($srcFile;$srcPict)
//--------------------- convert it using ImageMagick
---------------------
$convertPath:=System folder(Applications or Program
Files)+"ImageMagick\\" //user must install 32bit static version of IM
and be sure to change the path at installation time (default path
includes the version number)
If (Test path name($convertpath)=Is a folder) //make sure user has it
installed
$srcFileCmd:=$srcFile+"[0]" //add [0] because we only want page 1
of the document
$cmd:="convert -thumbnail
"+String($width)+"x"+String($height)+Char(Space)+Char(Double
quote)+$srcFileCmd+Char(Double quote)+Char(Space)+Char(Double
quote)+$dstFile+Char(Double quote)+Char(Carriage return)+Char(Line feed)
SET ENVIRONMENT VARIABLE("_4D_OPTION_HIDE_CONSOLE";"true")
SET ENVIRONMENT VARIABLE("_4D_OPTION_CURRENT_DIRECTORY";$convertPath)
LAUNCH EXTERNAL PROCESS("cmd.exe";$cmd;$output;$errorTxt)
End if
$0:=$dstPict
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I make sure that ImageMagick is installed into a folder in Program
Files called ‘ImageMagick’ so that I can hard code the path to the
‘convert' function above.
HTH,
Randy
