Re: Button images script

Thanks Jim, this works beautifully. I may however end up playing with the images to get them how I want them before I put them into the substack. Yet to be decided.

I noticed that the images in the substack are also resized, but when you re-open the stacks, all the images (and button images - but not buttons) are back to their original size. (I ran the script from a button and not a preopen card script.) For what I want to do this seems a bit of unnecessary processing as they would have to be resized every time the stack was opened. Do you think locking "size and position" (of the image) after the image have been scaled would stop this?

(But then again I can see the advantage in having a larger image to size as needed in different options within a stack - as I think aloud).

Thanks for sharing the script. It is helpful to see how others approach problems.

cheers

Greg,

Here is a utility which I use to deal with buttons in the main stack
whose image icons are in a substack. It relieves you of the need of
setting  to set the icon id and sizing the images and/or the buttons
all in one fell swoop.

1) Put all the images on card 1 of the substack (mySubstack below.)
Don't worry about size or position, that will be taken care  of
later. And resizing may distort the proportions. Doesn't matter if
they overlap.
2) Next go through the main stack (myStack below) and create buttons
with *the same name as the desired image in the substack* and in the
desired location on each card. Also adjust the size of the button to
the desired size of the eventual image. (Actually only the width
matters. The height will be adjusted to avoid distorting the image
proportions.)
3) Run setUp below from the main stack. All buttons will be assigned
icon numbers of the image corresponding to the button name and the
image in the substack is adjusted to fit within the button. And, as a
bonus, you get an image border. If you don't want the border just:
"set the showBorder of button tButtonName to "false." You can also
set the color and width of the border. You may want to tinker with
the edge number of ".98" below.
4)  You can add images and button later if necessary and rerun "setUP".
5)  Thanks to members of this list for help in developing this handler.



On setUpRev
   Lock screen
   repeat with i =1 to the number of cards
     set the defaultstack to "myStack
     go to card i
     repeat with j = 1 to the number of buttons
       put the short name of button j into tButtonName
       put the width of button j into theButtonWidth
       set the defaultstack to "mySubstack
       if there is an image tButtonName then
         put the id of image tButtonName into tImageID
         put the formattedWidth of image tButtonName into tImageWidth
         Put the formattedHeight of image tButtonName into tImageHeight
         put tImageHeight/tImageWidth into ratioOfHeightToWidth
         set the width of image tButtonName to theButtonWidth*.98 --
Leave an edge
         set the height of image tButtonName to
theButtonWidth*ratioOfHeightToWidth*.98
       end if
       set the defaultstack to "myStack"
       set the icon of button j to tImageID
       set the height of button tButtonName to
theButtonWidth*ratioOfHeightToWidth
     end repeat
   end repeat
   unlock screen
end setUpRev
