Resize all images in document

Question

Hello,
I have long document with 300+ images. I need to re size them all to W=63,5 mm and H=53 mm. I dig the Forum and find out this script from user "Harbs." but it is for re scaling images to certain percent:
This will scale all images to 90% of their current size:
  myGraphics = app.activeDocument.allGraphics;   for (idx = 0; myGraphics.length > idx; idx++) {    if(myGraphics[idx].constructor.name!="Image"){continue}    myGraphics[idx].parent.horizontalScale = 90;    myGraphics[idx].parent.verticalScale = 90;   }
And this will scale them to an absolute 90%:
  myGraphics = app.activeDocument.allGraphics;   for (idx = 0; myGraphics.length > idx; idx++) {    if(myGraphics[idx].constructor.name!="Image"){continue}    myGraphics[idx].horizontalScale = 90;    myGraphics[idx].verticalScale = 90;    myGraphics[idx].parent.fit(FitOptions.FRAME_TO_CONTENT);   }
Anyone knows how to make it to resize the images to specific size?
Thanks!

Setting width and height is a bit more complicated because you have to calculate the bounds (there isn't a width and height property for an image). I can't do it off the top of my head with javascript, but if you're using OSX this Applescript would resize from the upper left corner.
tell application "Adobe InDesign CC 2014"
    tell active document
        set properties of view preferences to {horizontal measurement units:millimeters, vertical measurement units:millimeters}
        repeat with x in all graphics
            set {a, b, c, d} to geometric bounds of x
            set geometric bounds of x to {a, b, a + 53, b + 63.5}
            tell parent of x
                fit given frame to content
            end tell
        end repeat
    end tell
end tell
