I am looking for an efficient way to perform the following operation; here is a minimal working code:

I have a MacOS(Big Sur) app based on an existing iOS app. The Catalyst app has 4 or 5 scenes(ViewControllers) open and tiled on the screen simultaneously. The user will bounce between scenes, interacting with the app to create some composite data. All the scene are open and visible (no overlap generally, but they can be moved around as desired).

In transitioning to the Catalyst environment with a single code base, I have needed to optimize the views to optimize the big screen, multi window environment. I do this by programmatically enabling/disabling or setting values on layout constraints in the viewWillAppear method of each view controllers in conditional compile blocks under #if targetEnvironment. Everything looks great when all the window scenes first open.

Here is the problem: When leaving focus to another scene, then returning to the original scene, the conditional layout is replaced by stock iOS layout. On regaining focus, the original scene does not call the viewController's

viewWillAppear or viewDidAppear once the scene is visible, it is always Foreground/Active even if it is not topmost with focus. It stays foreground/Active until actually closed. therefore

in Scene Delegate, sceneWillEnterForeground and sceneDidBecomeActive are never called after initially opening scene.

I have tried using the window event to detect change in focus:

I'm trying to export an image (PNG) which is larger than the maximum canvas size. I've tiled the canvas export, so that each tile is small enough to be generated (with toBlob). Now I need a way to merge the images together, but can't find a way that itself doesn't use a canvas. Is this possible somehow?

So, I am using plotly mapbox plotly.express.choropleth_mapbox to display colored tiles.

Ultimately what I want to do, is to overlay a scatter plot, whether a circle, symbols, etc. Some 'Point' coordinates on top of the colored tiles.

I am not aware of a way to combine scatter_mapbox as a trace to choropleth, so I tried to update mapbox and use the circle layer, below.

Note that I've done this with an outline from another .geojson file to draw an outline on the map (yay this part works), but the overlay of circles did not work. (Also tried symbol and did not work either.)

Was trying to troubleshoot if it was my geojson file or not, since I created the file on my computer. Tried creating both in python and with QGIS.

My goal: add markers/coordinates on top of a tiled geographic map.

Here is the code below which should allow you to see the same as me.

I havet this codepen: https://codepen.io/sp2012/pen/VwpyWdp . Unfortunately, this code is too advanced for me. The game has three maps. I want to keep only the first map and when the game is finished, if you click on the map the game restarts.

The code follows:

I'm trying to create a mailchimp template, but I'm having compatibility issues with background images within table cells.

Something like this, just gets ignored by the likes of Outlook etc:

In MATLAB when working with subplot I can merge axes from different subplots to create a larger subplot like:

I'd like to download inside Shiny a georeferenced PDF file (geoPDF) and for this a need some steps like convert the plot in ggplot format to tiff, populate the spatial coordinates, create a geo tiff, and finally my geoPDF. But several steps in downloadHandler() function in tempdir() directory results always in the error:

I want to tile the ground with ARKit using custom polygon that creates using selected positions on horizontal plan by user, but tiles are stretched and wont show properly, Maybe problem is from texture coordinates, What's wrong with this code?
