file name and image source

[Jellobus]

Hi all,

I wonder how to figure out the name of image source of the image "show" below
There are two ways to change images with my options.

1. set filename of image "show" to "/source_1.png"
2. put image "source_1.png" into image "show"

with method #1, the filename of image "show" indicates "source_1.png" as a name of image source, but with method #2, there is no indicator of image source.
Can I find out an original image name with method #2 ?

Cheers,

Louis

Hey there Jellobus, with method 1 there is only a referense to the link of the image, no actual data are being imported into livecode, with method 2 the data are being imported into livecode and in your image(show in this case) so there is no need for for image source.

Hi zaxos,

sorry for the unclear explanation. let's say its not file name but it's an original image source name.

with setting filename #1, you can see the root of the original image but with #2 you can't find out where the original image came from. you know what I am talking about?

well with method 1 you can see the the source beacoz you need you have linked your image with that source, if for example you:

Code: Select all

set the filename of img "Show" to "C:\test.jpg" 

and then you move image test.jpg away from "C:\" the image in livecode wont work anymore beacoz it is linked with an image "C:\test.jpg" that dosent exist anymore...
You need to understand the difference betwen these 2, in case 1 you use an external image , in case 2 you import the image in your stack wich in return is stored along with your program.exe when you compile it.
If you already understand this then my guess is that you want to be able to know the source of your image anyway so since livecode dose not keep a record of where the image came from, you should. here is a quick example, you save the link of the image inside a custom property of the imported image

Code: Select all

put "C:\source_1.png" into theImage
put img theImage into image "show"
set the imageSource of img "show" to theImage

this will store the link of the image inside a custom property of image "Show"

Code: Select all

put the ImageSource of img "show"

and this will show you what is inside that custom property

Hi zaxos,

Thanks for the detailed explanation. The main reason I want to include all images into the stack is to hide files. whenever I saved as standalone application for the desktop(window) environment, the copy files is created into the folder where the main app stack created. users can open the file folders... I don't want to users see the image files of the app directly. Do you know how to hide copy files without importing them into the stack?

Thanks a lot in advance,

Louis

Hi Louis,
Just for a test I imported 2 images on to card 3 of my stack then ran this on card 1

Code: Select all

on mouseUp
   put the name of img 2 of cd 3
end mouseUp

And it returned the correct target.
Does that answer it for you?

Hi Louis,

to answer your original question:
If you IMPORT an image file into your stack then there is NO reference to the original image file anymore.
You can even delete the original file, that does not affect the imported image.
So no, you cannot find out what and where the original image has been after importing!

But instead of using the images directly you can always use a BUTTON and set its ICON property to display different images dynamically!
That's what I do most of the time

@Zaxos
BEWARE: "imagesource" is a reserverd word!
Add a little c (for Custom property) in front of it and it will work -> the cImageSource of xyz


Best
