I want to hold precise original size of a scanned graphic when pasting into a Pages document, however, when I use the inspector and select "Original Size" the size of graphic is much different.  How can I do this?

Pages, OS X Mountain Lion (10.8.3)

    You can try opening and resaving the image with the actual Scale/Resolution in Preview's Tools but from my experience Pages just plain gets it wrong most of the time.

     

    You can also go the other way and make a shape the right size in Pages and make the image fit.

    Nope!

     

    Sometimes the problem is not Pages in that the resolution hasn't been set or is set wrongly. The presumed resolution then is 72dpi, which often blows up the image to huge dimensions.

     

    Have you checked what the resolution of your images actually is?

    Open the image in Preview and check what size/resolution it reports under:

     

    Menu > Tools > Adjust Size

     

    I just experimented with a jpeg, setting it to 300dpi. It was approximately that in Pages but still wrong by about a cm.

     

    Apple has stuffed this up, but since Pages is getting minimal to no loving these days, I doubt they are about to fix it.

     

    This was using Insert onto an oversize blank Layout page with plenty of room for it to fit, Pages will auto-rescale inline images to fit available space. Something I find useful for my tutorial documents.

    In the Metrics Inspector, have you tried typing the desired Width and Height in those respective boxes?

    Can you scan to pdf? Or convert the scanned image to pdf without rescaling?

     

    As far as I have been able to determine, pdf is the only format where Pages' Original Size means what we would expect; for other bitmap formats Original Size seems to mean 72 pixels per inch (i.e. for a zoom of 100%, one image pixel equals one screen pixel).

     

    Otherwise, Walt's suggestion is probably the simplest solution. When you scan at 300 dpi, note the exact dimensions of the area you are scanning, and then enter those dimensions in the Metrics inspector.

     

    I have done something similar to what you are doing for drawings for irrigation designs, to take advantage of Pages' text handling, but using CADintosh from Lemke Software to do the line drawings. In that case, the line drawings are exported to pdf as vector objects, so there is no quality issue. The learning process isn't trivial, but it is inexpensive shareware, and most features are availlable without even registering. If this is something you do a lot, it might be worth considering.

    Steve,

     

    I just copied a 19 inch by 13 inch pdf image of a drawing to my clipboard (opening it as a new document in Preview confirmed the size). I created a new Pages page layout document for 13 by 19 paper, in landscape (that happens to be the largest size I can print at home, so I had something in that size handy, otherwise size should be arbitrary). I pasted the drawing from the clipboard into the Pages document, where it appeared at about 50% of original size. I suspect Pages scales images to a size that fits comfortably into the window so that they can be easily manipulated with the mouse (i.e., all the handles are well inside the margins).Clicking the Original Size button in the metrics inspector restored the image to 19 by 13. Dragging and dropping a pdf file from the Finder works similarly (with the added advantage that the image has a unique name). My limited experimentation with a bitmap pdf file also worked that way.

     

    So, for me at least, using pdf doesn't necessarily import at the size as drawn, but it does allow me to restore that size without having to measure anything. With a PNG or TIFF or JPG image, the Original Size button displays the image at 72 dpi, so I have to know either the original dimensions or the original resolution, from which I can calculate the size.
