I'm trying to write a console script to replace some placeholder text in
a pdf (eg. XYZ) with a variable generated by web script supplied to the
command line.
I can go through and read properties of the pdf, but I can't seem to
change any text. I don't know if I need to add operators to the stream
or what, none of my experiments have worked. All I can do is get the
stream text and modify the variable:
text = stream.getText();
text = text.replace("XYZXYZXYZ", ycode);
print("textnow: "+text);
Is it possible to do such a search replace from a console script?
Any help is much appreciated.
Here's my experimental code, it's just a mess, but at least you can see
what I've been up to if you want.:
// Console: addycode
function addycode_help() {
print(tr("Usage:"));
print("addycode ["+tr("input file")+"] ["+tr("text")+"]");
print(" "+tr("Input file must exist"));
// print(" "+tr("Output file must not exist"));
exit(1);
}
function addycode_fail(err) {
print(tr("Adding code failed!"));
print(err);
exit(2);
}
p=parameters();
if (p.length!=2) {
addycode_help("addycode "+tr("is expecting 2 parameters"))
}
inFile=p[0];
ycode=p[1];
if (!exists(inFile)) addycode_fail(tr("Input file '%1' does not
exist").arg(inFile));
//if (exists(outFile)) addycode_fail(tr("Output file '%1' already
exist").arg(outFile));
//if (inFile==outFile) delinearize_fail(tr("Input and output files must
be different"));
if (1) {
// print(tr("added code.")+" :"+inFile+" -> "+text);
outFile = "/home/chris/pdf/outFile.pdf";
delinearize(inFile, outFile);
print("done delin");
pdf = loadPdf(inFile, true);
page = pdf.getPage(1);
stream_count = page.getContentStreamCount();
print("numstreams: "+stream_count);
if (!stream_count) {
print("no count");
exit(1);
}
//dict = page.getDictionary();
//print("dictionary: "+dict.getText());
//print("TEXT: "+page.getText());
for (i=0; i< stream_count; i++){
stream = page.getContentStream(i);
print("it: "+stream.getText());
//print("decstream: " + stream.getDecoded());
text = stream.getText();
text = text.replace("XYZXYZXYZ", ycode);
print("textnow: "+text);
//stream.insertOperator();
//op = stream.getFirstOperator();
//iter = op.textIterator();
//while (op){
// print("op : "+op.());
// op = iter.next();
//}
}
//print "numstreams: "+stream_count;
//print "stream: "+stream;
pdf.unloadPdf();
} else {
addycode_fail(error());
}
