Thanks for the quick reply Robin re the drawImage.

I'm also having another problem -- this one with pdfgen\textObject.py

Based on my understanding, if I send a trim=0, no whitespace should be removed.

However, I noticed that the code removes leading whitespace on string types (which is a problem for me) even with a trim=0.

I have edited my local version to be this (see the comment with the 'dr'  in it -- that's what I added to preserve leading whitespace):

    def textLines(self, stuff, trim=1):
        """prints multi-line or newlined strings, moving down.  One
        comon use is to quote a multi-line block in your Python code;
        since this may be indented, by default it trims whitespace
        off each line and from the beginning; set trim=0 to preserve
        whitespace."""
        if type(stuff) == StringType:
            if trim==1:
              lines = string.split(string.strip(stuff), '\n')
            else:
              lines = string.split(stuff, '\n') # preserve leading white space dr 10-31-02
            if trim==1:
                lines = map(string.strip,lines)
        elif type(stuff) == ListType:
            lines = stuff
        elif type(stuff) == TupleType:
            lines = stuff
        else:
            assert 1==0, "argument to textlines must be string,, list or tuple"

        for line in lines:
            self._code.append('%s T*' % self._formatText(line))
            if self._canvas.bottomup:
                self._y = self._y - self._leading
            else:
                self._y = self._y + self._leading
        self._x = self._x0

Any idea if this will be corrected in 1.17?

Thanks,
