I was attempting to draw an image rotated and centered onto a PDF. The actual image would vary and was not under my control - the user can upload any size image. I went through a lot of brain damage trying to make FitImage work, but could not do it. I ended up using DrawRotatedImage and got it to work with a little bit of trouble. Here's the code in case anyone gets stuck with the same problem (Visual FoxPro code).

    PRIVATE lMaxHeight, lMaxWidth, lWidth, lHeight, lAdj
    lMaxHeight = 45
    lMaxWidth = 90
    lWidth = opdfedit.o.ImageWidth
    lHeight = opdfedit.o.ImageHeight
    lAdj = 0

    IF lHeight > lMaxHeight
     lAdj = lMaxHeight / lHeight
     lHeight = lHeight * lAdj
     lWidth = lWidth * lAdj
    ENDIF

    IF lWidth > lMaxWidth
     lAdj = lMaxWidth / lWidth
     lHeight = lHeight * lAdj
     lWidth = lWidth * lAdj
    endif

lReturn = opdfedit.o.DrawRotatedImage(lpdfx + lHeight, lpdfy + (lWidth / 2), lWidth, lHeight, 90)

lPDFX = the left edge of the image. LPDFY = the mid-point where you want things to center around.
