in thread PDF API2 - landscape and rotating text and image

Hi Ken,

Thank you so much for your explanation and great working code! Wouldn't have thought of a For loop to do the left and right tasks.

I have one question for the line below:

$gfx->image($cfg->{img}, 0, 0);

The values of 0,0 - that outputs the image in its original size (am I right?). I tried with values like 200, 200 to get bigger images but the images don't appear. How do I output the images to bigger sizes?

Thanks you for your great help once again :))

    You should look in PDF::API2::Content for information on image(), transform(), and related methods. In particular, look at the "External Objects" and "Coordinate Transformations" sections.

    The '0, 0' to which you referred are co-ordinates, not sizes. As the code already sets the co-ordinates via the '-translate' option of transform(), further modification of the co-ordinates by image() is not wanted.

    The image() method has a number of forms allowing you to change width, height, and scale. There's also a '-scale' option for transform(). Note that if you change the size, you'll also need to adjust the co-ordinates accordingly.

      Ok, thanks!

      The transform() method is new to me. Took a quick look and saw you can do scaling and skewing with it.

      Great learning from your earlier code, many thanks :))
