Zoom-in button for image gallery

#1 Post by facesit-inc » Wed Apr 21, 2021 6:20 pm

Hello,

I'm having a hard time making a button, which would zoom-in the current gallery item. I tested that the button appears on the screen correctly:

vbox xalign 0.98 yalign 0.1:
imagebutton:
idle "gui/zoom_idle.png"
hover "gui/zoom_hover.png"
action NullAction()

but honestly I simply don't understand, which action should do the trick. I've already tried the zoom (as in ATL), but I get the error that this parameter uses the screen language. Studying the screen language, I found the im.Scale parameter, but it seems I can't use it correctly as well.

Which action should be placed here?

P.S. By the way, I'm placing this button near the grid and return button on the gallery screen.

There are several ways to do it. If you want to use ATL transform to an image in a screen, do:

Code: Select all

add “image_name.png”:
     at TransformName
You can give this a condition (if) so it can be shown and hidden by button actions.
Another way is to show a different screen containing the zoomed in image, or you can also call a label on action and return to your screen when done.
The best method depends on what you exactly want to achieve~

Thank you. It's more complex than I've thought, but doable.

Came across this thread and found that there is an one step action you can do to show images with transform on screen:
viewtopic.php?t=45661

Code: Select all

Function(renpy.show, "my_image", at_list=[my_transform])

Sorry for the late answer, did not see that you responded again. I defined the new transform (galleryzoom) and used a test image. It doesn't seem to do anything, I don't even get any error, it just doesn't work.
