Let's say my UI looks like this:

enter image description here

What I want to do is to change some Image Editor bpy.context.window_manager.windows[0].screen.areas[1] options through my addon. For example, to change the image of Image Editor I do sometihng like this:

texture_name = "face.png"

area = bpy.context.window_manager.windows[0].screen.areas[1]
area.spaces.active.image = bpy.data.images[texture_name]

In case I want to change, let's say the header of Image Editor. If it will appear or not. Or the zoom ratio of the image. How I'll do that?

I found this bpy.context.space_data.show_region_header = False and this bpy.ops.image.view_zoom_ratio(ratio=1.0) using right click, but I don't know how to use it. Because for example if I use bpy.context.space_data.show_region_header = False from my addon, it will not hide Image Editor's header but 3D Viewport's header.

I also try to iterate through areas and do bpy.context.space_data.show_region_header = False and bpy.ops.image.view_zoom_ratio(ratio=1.0) from there. But I can't find the syntax. Because for example, bpy.ops.image.view_zoom_ratio(ratio=1.0) should be something like area.spaces.view_zoom_ratio(ratio=1.0). Which doesn't work and gives me this error AttributeError: 'bpy_prop_collection' object has no attribute 'view_zoom_ratio'

So, any idea how can I do this?

Find Image Editor views from screen.areas with filtering and call view_zoom_ratio operator with Overriding Context.

import bpy

override = bpy.context.copy()

for area in bpy.context.screen.areas:

    #if area.type != 'IMAGE_EDITOR' or area.ui_type != 'VIEW': # Image Editor View only
    #if area.type != 'IMAGE_EDITOR' or area.ui_type != 'UV': # UV Editor View only
    if area.type != 'IMAGE_EDITOR':
        continue

    area.spaces.active.show_region_header = False

    override['area'] = area
    bpy.ops.image.view_zoom_ratio(override, ratio=1.0)

    area.tag_redraw()

  • $\begingroup$ First of all thank you for your time!!! To make it work I had to replace if area.type != 'IMAGE_EDITOR' or area.ui_type != 'VIEW': with if area.type == 'IMAGE_EDITOR': and remove the continue. Would you like to check it again and change it so to mark your answer as correct? $\endgroup$

    $\begingroup$ Note that I used area.ui_type! ='VIEW' to exclude the UV Editor View. So my script works only on the Image Editor View. Do you want a script that works in UV Editor View as well as Image Editor View? $\endgroup$

  • $\begingroup$ One "subquestion"! In case I have three image editors opened and for example I want to point the second one? $\endgroup$
