Image not positioning correctly inside frame?

[Ryue]

I'm trying to be .... imaginative and have a background image upon which another image is displayed. I used a frame and subframe for this.
Now what I wanted is the second image to be centered inside the frame image, but somehow it is still displayed to the right (even if I use xysize 1366,200 in the
subframe).

What am I doing wrong there?

Example image (b/w image is the one I wanted centered):

Code: Select all

screen DescriptionMap(imageName):
    frame:
        xysize 1366,200
        top_margin 22
        left_margin 200
        
        background "Graphics/GUI/mapbox.png"
        
        frame:
            xalign 0.5
            yalign 0.5
            background imageName

Try changing the value you have for left_margin from 200 to something greater. Margins are how far away from the left or right side the image is, so in your code, left_margin = 200 means that the image is 200 pixels away from the left side of the frame.

although that margin should only count for the mainframe and thus for positioning it and thus not affect the subframe within the mainframe or am I wrong there?
(I need the main frame at exactly that position where it is now)

As an update here even not using a second frame somehow does not bring a solution there:

Code: Select all

screen DescriptionMap(imageName):
    frame:
        xysize 973,209
        top_margin 22
        left_margin 200
        
        background "Graphics/GUI/mapbox.png"

        image imageName xalign 0.5 yalign 0.5

The image is a bit more to the right now but still far from being centered inside the frame. I have to add xanchor 0.37 to the image itself which I find.....strange.
Any clues there?

margins do not position the frame but the elements inside it. Your main frame has a left margin of 200 and a right margin of 0 (I presume, is not defined). Thus, the xcenter of the frame is 100 pixels to the right.
Add xoffset -100 to the subframe to center it.

that means then I would also need to put left_margin 200 into the subframe?

Why?

Why?

I asked as I'm not 100% getting what you meant

I don't fully understand what do you need.
In your example you use a subframe with a background only to put an image in the center of the main frame. I suggest you to use "add" to put an image (and position it) in the main frame and forget the subframe.
I also suggest to forget all the margins. They do not serve to position the frame (as I presume you think from your explanation) and I think they are confusing you.
If you need a space between the left limit of the screen and the frame, use xpos 200.
