Another problem with display.save()

Hi there!
I use display.save() trying to save an image that i want to use later.
My problem is this: When I save the image, this one is what i see instead of watching the elements I've got before pressing the save button, i.e., I want to save the image but not to watch the result (image.jpg) in my iPhone screen.

Is it possible?, what am I doing wrong?

This is my code:

display.setStatusBar( display.HiddenStatusBar )
local ui=require("ui")
 
local width,height=display.contentWidth,display.contentHeight
local background=display.newImage("background.jpg")
local rect=display.newRect(0,(height-80),width,height)
rect:setFillColor(174,78,0)
local my_image=display.newImage("foo.png",90,90)
 
local function saving()
        local baseDir = system.DocumentsDirectory
        local toSave=display.newGroup()
        toSave:insert(background)
        toSave:insert(my_image)
        display.save(toSave,"image.jpg",baseDir)
end
 
local save_button = ui.newButton{
        default = "save_button.png",
        over = "save_button.png",
        onRelease = saving,
        emboss = true
}
 
save_button.x=width/2
save_button.y=height-35

can you elaborate a bit more.

Hello!

Thanks for your reply, Carlos!
That's all my code.
Before pressing the save button that's what I can see in the simulator: www.ogrove.net/before.png
And after pressing the save button, that's what I see: www.ogrove.net/after.png

What I want is to save the image but watch the scene and work as before pressing the button.
Now, pressing the button the image is what I get and I can't interact with the app.

Could you tell me what am I doing wrong?

TIA

thats because you are creating a new group and inserting the image into the group. the stacking order of the group will put the image on top.

ergo why you can't go back

That's right!, but I need to create a new group, isn't? I think it is not possible to do it other way...
Must I send the image to the bottom of the group? Is it a good practice?
If I try to remove the image I don't see anything at the scene.
I'm confused... I thing it would possible to save the image and don't added it to the stack (only create a jpg file)

or you could just do

1
2
3

toSave:insert(display.newImage("foo.jpg",0,0))
display.save(toSave,"image.jpg",baseDir)
toSave:RemoveSelf();

Mmmmm... well, I need to save the background too (because can't save png images), and my idea is to add more elements to the group "toSave"
I don't know if I am understanding you well, but I think with your code I only could save my foo.png image, isn't it?

As you have made noticed, I am a newbie and I appreciate so much your help.

This is my code now, after your instructions:

display.setStatusBar( display.HiddenStatusBar )
local ui=require("ui")
 
local width,height=display.contentWidth,display.contentHeight
local background=display.newImage("background.jpg")
local rect=display.newRect(0,(height-80),width,height)
rect:setFillColor(174,78,0)
local my_image=display.newImage("foo.png",90,90)
 
local function saving()
        local baseDir = system.DocumentsDirectory
        local toSave=display.newGroup()
        local my_image2=my_image
        toSave:insert(display.newImage("background.jpg"))
        toSave:insert(display.newImage("foo.png",90,90))
        display.save(toSave,"image.jpg",baseDir)
        toSave:removeSelf()
end
 
local save_button = ui.newButton{
        default = "save_button.png",
        over = "save_button.png",
        onRelease = saving,
        emboss = true
}
 
save_button.x=width/2
save_button.y=height-35

On this way, it seems it is a duplication of code, isn't it?

Carlos??
Anyone??

call display.captureScreen( ) then the save the resulting image.

hide all elements that you don't want on the screen right before calling display.captureScreen( )

thens how them

Thanks, Carlos!
I'll try as you say and I tell you.
