I want to export a MAUI control to an image. In WPF we have "RenderTargetBitmap". I tried to use it on MAUI but the method "RenderAync" need a Microsoft.UI.Xaml.UIElement" but the controls of MAUI are "Microsoft.Maui.Controls".

Hi @JosLuisOrihuelaConde-1829 ,
You said "I want to export a MAUI control to an image", I'm not sure if you want to capture the full app window, if so, Essentials : Screenshot is a good option. Or you just want to capture the control itself or any others behaviors.
Besides, I saw that when you tried to use RenderTargetBitmap and met this error: the method "RenderAync" need a Microsoft.UI.Xaml.UIElement" but the controls of MAUI are "Microsoft.Maui.Controls".
You could try to find the handle of this MAUI control, and get handler.PlatformView, which is a native control of type Microsoft.UI.Xaml.UIElement. After that you can set native control properties, invoke native control methods, and subscribe to native control events and so on.
renderTargetBitmap.RenderAsync(handler.PlatformView, 300, 300);
For more details, refer to Customize .NET MAUI controls with handlers.
Best Regards,
Wenyan Zhang

Thank you, it worked!
Previously I've tried with Essentials and used Screenshot, but I needed only to save to a file some components of the UI, not the whole window. Also, Screenshot takes the title bar of the window too.
Glad you solved this issue, I converted it to an answer, you could check it.
Can you explain this to me? RenderTargetBitmap is in WPF, how can I implement it in MAUI? Also the namespace System.Windows.Media.Imaging from which the RenderTargetBitmap comes is in .NET Framework, and I don't think it is supported in MAUI, right? I am really exhausted from finding how I can
print or at least convert a specific content from a page to image. Is there a way to do that? In MAUI? I have almost completed my project, I just desperately need this!

Different RenderTargetBitmap. MAUI is implemented on top of WinUI3 for Windows, and you can use WinUI's Microsoft.UI.Xaml.Media.Imaging.RenderTargetBitmap along with the Handler's PlatformView as Wenyan explained.
So, there's no abstract method for printing or converting a view to image right? Like I have to implement one for Android, and other for WinUI to do that. Still though, thanks for this, saved me a bit of time.
Correct. There isn't an abstraction to capture an individual view to an image. Screenshot abstracts capturing the whole window.
You can look at the Screenshot source as a model for how to capture views on each platform.
Thanks! Actually I recognized that earlier, and started my search for the solutions to implement on each platform. Android was the problem for me. But I found it in the first try. But since it was in Java, I had a hard time implementing that in MAUI. For windows, I am quite familiar with WinUI3, so it was not too much of a deal.
I have a question though, do you know how I can enable Intellisense for the code inside #if WINDOWS?
They are greyed out and oof.
Also, do you have any ideas regarding printing in Android (possibly Windows too)? I haven't checked the Windows one, as I have done that in WPF, and I do believe, it can be similar.
Can you please post new threads for your new questions? See How to write a quality question / Ask one question at a time.
There's a project selector at the top of your editor tab that will let you choose which target the editor shows.
I'm not sure what you're looking for re: printing, so please provide more details on your scenario in a new question. At a very high level, both Android and WinUI use the same PrintManager name for their printing intro class.
Thanks for the answer mate! Actually, I have already asked my question on GitHub, so now waiting for the answer while I do other things. Well, I have found a few things related to Printing, will do a little more search.
