SOLVED - putting image in image holder

[admin12]

I have a background image object called ImgBack
I placed a button and wrote the following script:

on mouseUp
put "C:\LiveCode Builds\CSUSA_Database23\white_water.jpg" in image ImgBack
end mouseUp

I want to be able to change the image object, ImgBack by pressing the button.

What is the correct syntax?

And yes, when I get a free moment, I will watch the videos Klaus keeps telling me to watch.

Thanks.

Hi Mike,

hints:
LiveCode internally ALWAYS uses the UNIX path delimiter -> SLASH -> /!
ALWAYS Quote NAMES/STRINGS!

two options:
1. "import" (the binary data of the) image into your stack:
...
put url("binfile:C:/LiveCode Builds/CSUSA_Database23/white_water.jpg") into image "ImgBack"
...

2. or just set the filename:
...
set the filename of img "imgBack" to "C:/LiveCode Builds/CSUSA_Database23/white_water.jpg"
...

Klaus,

Ok, so to go one step further, if I wanted someone to simply choose a image from their computer, how would I replace the absolute path with the more dynamic one?

Would it be something like this: set the filename of image to [variable passed after file browser]

I have to look up how to load an image - I know it's in the manual.

To throw another curveball, this is going to be a web app, so when someone chooses an image to load as background, how do I store it? I would rather store it locally since I want multiple users to be able to "skin" the background with any picture they want.

Thanks for your help. Every piece of knowledge gets me one step closer to proficiency.

Exactly! As long that variable holds a valid pathname!

You should also check (some of) these stacks:

Oh, sorry, I don't have much experience with Relets.
But some "specialfolderpath" like "preference" should work there, too, so you can write your infos to that folder.

OK. I got it all working - thank you.

Now, another question.

When I load an image in and set the image lock - how can Live Code resize the image, but keep it's proprotions? Right now it stretches the image to fit in both directions. I want to lock the aspect ratio, but resize to the size of the image box (in this case, 140 x 140)

Also, I want to be able to store both the image and the smaller resized image for later retrieval. How would I do this?

Hi Mike,

remember your old school days? And the "rule of three"?
That's what you need to calculate here

Will check my archives for some code snippet.
