[Sigh] You old pirate you

Would strict checking catch this, as it does in Perl and other lingoes?

Yes, but now I'm confused.
From the Main menu Edit > Preferences > Script Editor select Strict Compilation Mode
or
From the Script Editor menu Edit select Variable Checking
I know the second one works. Is it the same as the first one?

First the good news: the delete now works and it fixes the situation of overlapping or non-resizing images. Left to do: Android reverses portrait and landscape (i.e. camera landscape = image portrait)

Hmmm don't think so: I'm getting different results for the "preferences" and the "variable checking" methods. The 2nd one seems stricter. I've declared a "local cProfileImage" at the top of the card script. Variable checking complains about the code snippet below with:

card "UserProfile": compilation error at line 28 (Chunk: can't create a variable with that name (explicitVariables?)) near "MaxHeight", char 12

whereas Preferences remains entirely happy (No errors occurred). Dunno what it's complaining about to be honest. Perhaps we should split into a new subject ...

Code: Select all

         # an image was selected
         put the formattedHeight of the last image into W
         put the formattedWidth of the last image into H
         set the name of the last image to "cProfileImage"
         set the lockLoc of image "cProfileImage" to true
         set resizeQuality of image "cProfileImage" to "good"
         
         put W / H into AspectRatio
         put round(MaxHeight * AspectRatio) into NewWidth
         answer "W x H = " & W && "x" && H && "(" & AspectRatio & ")" & return &  "New:" && NewWidth && "x" && MaxHeight with OK 
         
         lock screen
         # first set the new dimensions
         set the height of image "cProfileImage" to MaxHeight
         set the width of image "cProfileImage" to NewWidth
         # then position the scaled image
         set the left of image "cProfileImage" to 40
         set the top of image "cProfileImage" to 300
         unlock screen

You'll now have to list all of your variables upfront just like you did with cProfileImage.

I think I have seen the flipped landscape/portrait but I don't recall a solution.

Edit; No I am wrong.

Variable checking causes LiveCode to perform a stricter check
of your scripts. Using any variable without declaring it first, or
using a literal string without encloning it in quotes causes a
compile error. This behavior can be useful in tracking down
certain subtle problems such as misspelling a variable name.

So that isn't going to help catch spelling mistakes

Edit 2; in your strings.

Playing with that rotate/angle stuff right now, but this "flipping" thing is pretty resilient it appears

When I get to grips with it I'll post of course. Thanks a zillion so far!
