Pinch resizing more than one image on a card

[tyarmsteadBUSuSfT]

I am able to pinch resize one image on the card, but am having problems if I have more than one image on the card. Is it possible to pinch resize more than one image on a card? I've tried to differentiate which image at the touch start code with and if statement. Am I on the right track?
Thank you
Ty

Hi Ty,

you can check "the target" on touchstart, then you know if and what image to handle.
Is that what you mean?

Yes, I tried that, but let me re look at the code. Now that I know I can do, that helps a great deal.
Thank you
Ty

Klause, This is where I am starting with the touch start:
local sinputId
local sTouchArray, sFRAMEWIDTH, sFRAMEHEIGHT

on touchStart pId, pX, pY
get target
if the target is image "itemPic1" or image "itemPic3" or image "itemPic4" then
put it into tPic
#to check if it is putting the target into tPic
answer yes
put the width of image tPic into sFRAMEWIDTH
put the height of image tPic into sFRAMEHEIGHT
else
end if
#to see if it is the correct target
answer the target
end touchStart

I can't get the if to work.

if the target is image "itemPic1" or image "itemPic3" or image "itemPic4" then
if "itemPic1" is in the target or "itemPic3" is in the target or "itemPic4" is in the target then

See if that works, didn't test it.

Hi guys,

this should to the trick, please note the correct use of "IF... OR... OR"

Code: Select all

local sinputId
local sTouchArray, sFRAMEWIDTH, sFRAMEHEIGHT

on touchStart pId, pX, pY
   put the short name of the target into tImageName   
   if tImageName = "itemPic1" OR tImageName = "itemPic2" OR tImageName = "itemPic4" then
      put the width of image tImageName into sFRAMEWIDTH
      put the height of image tImageName into sFRAMEHEIGHT
   end if
   
  ## to see if it is the correct target
   answer the target
end touchStart

Klause, thank you that part is working, but clearly I'm doing something else incorrectly. I want the user to be able to resize any of the three images that they have taken using the camera on this card card. I had it working for one image but when I started trying to use variables, that is when I ran into the problem of none of the images resizing.
Thank you so much for your help.

Hi Ty,

Klaus, my name is Klaus, without any E!

OK, maybe adding:

Code: Select all

local tImageName

will help?

Question:
What does setting the textsize of an image do except not throwing an error?

Klaus,
That did the trick.
Thank you and I apologize for the "e". I appreciate that as people often drop the e"e" from my name.
