I have a situation that maybe someone has already solved in a more efficien=
t manner.  When converting a tiff image to PDF I use the drawImage method o=
f the PDPageContentStream.  The tiff image has a resolution of 200 DPI whic=
h is 1700x2200.  When PDFRenderer renders this image from the resulting PDF=
 page  it does so at the PDF default of 72 DPI which logically translates t=
o page 23 inches by 30 inches when applied to the original iamge size of 17=
00x2200.  Since I don't know after the fact what DPI a image object on PDF =
page was drawn at I came up with down scaling the image at PDF creation tim=
e to 72 DPI.  I'm sure there must a better way one of you computer science =
PHDs have come up with.
