Question

Если приложение было на iPad, как бы вы получили изображения, которые находятся на этом iPad?

Answer 1

Следующее из моего проекта. Он должен работать именно так.

function rescale theImgWidth,theImgHeight,theCdWidth,theCdHeight 
    if theCdWidth/theImgWidth < theCdHeight/theImgHeight then 
    put theCdWidth/theImgWidth into myRatio 
    else 
    put theCdHeight/theImgHeight into myRatio 
    end if 
    put theImgWidth * myRatio into myNewWidth 
    put theImgHeight * myRatio into myNewHeight 
    return myNewWidth,myNewHeight 
end rescale 

on pickPhoto 
    set the visible of the templateImage to false 
    if the environment is "mobile" then 
      mobilePickPhoto "library" 
      put the result into rslt 
      if rslt is "Cancel" then 
       exit pickPhoto 
      else 
       if there is an image "Photo" then 
        delete image "Photo" 
       end if 
       put the long id of the last img into myImage 
       set the name of myImage to "Photo" 
      end if 
    else 
      answer file "Choose a picture..." with type "GIF|gif|GIFf" or type "JPEG|jpg,jpeg|JPEG" or type "PNG|png|PNGf" or type "All files|*|*" 
      put the result into rslt 
      if the result is "Cancel" or it is empty then 
       exit pickPhoto 
      else 
       put it into myFile 
       if there is an image "Photo" then 
        delete image "Photo" 
       end if 
       create image "Photo" 
       set the filename of it to myFile 
       put it into myImage 
      end if 
    end if 
    if there is a myImage then 
      put rescale(the formattedWidth of myImage,the formattedHeight of myImage,the width of this cd,the height of this cd) into myWH 
      set the width of myImage to item 1 of myWH 
      set the height of myImage to item 2 of myWH 
      set the loc of myImage to the loc of this cd 
      show myImage 
    end if 
end pickPhoto
