Transforming coordinates, Forms XObject

I am having trouble getting the transformation matrix to work when painting a form xobject that contains an image xobject. Here is the pdf code:

I am trying to:

    + Make an 8.5 x 11 inch page (612 by 792)
    + Make a form xobject that is also 8.5 by 11 inches
    + Put a graphics image (width=1272, height=718) on the form
    + Put the graphics image at x=100, y=100 on the form, size the graphics to w=127, h=71

When I open the file with Acrobat 6.0 the graphic does not paint and when I examine the object using Preflight, list-all-images I see a message:
Outside visible page area.

Expanding Detailed Information- Graphic State Properties- Images- CTM, I see the following numbers:


I have no idea how I told Acrobat to use those numbers. How do I tell Acrobat to paint the graphic at the spot described above.

Next, I plan on writing text over the form by putting Td commands in the page object. Do you see any problems with this.

Thanks in advance.

You need to read the section about transformation matrices in the PDF reference at least a few times and potentially play around with working files a few times to get an idea about how they work.
I don't have time right now to look at your PDF file, I may be able to do this later today or tomorrow.
There is no problem with how you want to use the Td command.
More once I had a chance to look at the file.

One more thing: Are you sure that your XObject works correctly? You can verify this by just using the XObject as the page content. This helps to get the XObject debugged.

The image xobject works. I substituted its object number on the Page Resource object to test it. (The image looks horrible, I plan on fixing that next)

OK, in that case, all you need to do is to place the forms XObject in it's original size on the page:

1.000000 0.000000 0.000000 1.000000 0.000000 0.000000 cm
/XObj1 Do

Why are you placing the image into a forms object, and then add that into another forms object? You can just put the image into the resources of the page and place that.
