The 10.2.7 runtime has the class 'AttributeLabelClass' that allows you to format the labels for graphics and add it to a GraphicsLayer such that all Graphics with a certain attribute will render the same way.
Does anyone know if anything like this survived into the 100.0+ timeframe? I've been looking all over for this with no luck (which usually means it's right in front of my nose).
I'm fairly sure something like this exists because I've seen prototype demos of their efforts to resolve label confliction rendering issues.
We're hoping to have this feature back in Update 1. The public API might not be fully complete by then, but you'll at least be able to set everything with the json definition, and a more full-blown API for all the properties by Update 2.

I am looking at image snapshot testing to visual regressions in my app. My understanding is that serialized testing will make JSON representation of the DOM and compare a base version to a changed version. This will find copy and markup changes but will not be able to tell what actually changed in regards to how the markup was rendered. In other words, if you have a class on a div that set the font size and color, the test would only know the class existed, not what it was set too.
I was speaking to a friend who said you could get this data with serialized tests, but wasn't able to elaborate, only that he's "pretty sure you can do that". I did some research on this and haven't been able to find anything. As a last step, I figured I'd reach out and see if I'm missing something.
Is there way to make serialized snapshots compare the copy, markup and the styles associated with that markup?
Ultimately, I need to tests that can determine the changes I gave as an an example, but I want to make sure I'm not moving towards image snapshots naively.
I'm making an isometric city builder using Monogame Extended and Tiled. I've got everything set-up and now i need to somehow access the specific tiles so i can change them at runtime as the user clicks on a tile to build an object. The problem is, i can't seem to find a "map.GetLayer("Layername").GetTile(x,y) or .SetTile(x,y) function or something similar.
Now what i can do is edit the xml(.tmx) file which has a matrix in it that represents the map and it's drawn tiles. The problem with this is that i need to build the map in the content pipeline again after editing for the changes to be displayed. I can't really build at runtime or can i?
Thanks in advance!
Something like this will get you part way there.
var tileLayer = map.GetLayer<TiledMapTileLayer>("layername");
TiledMapTile tile;
if(tileLayer.TryGetTile(x, y, out tile))
{
// do something with tile
}
However, there's only a limited amount of things you can actually do with the tile once you've got it from the map.
There's no such thing as a SetTile method because changing tile data at runtime is not currently supported. This is a limitation of the renderer, which has been optimized for rendering very large maps by building static geometry that can't be changed once it's loaded into the graphics card.
There has been some discussion about building another renderer that would handle dynamic map changes but at this stage nothing like that has been implemented in the library. You could always have a go at implementing a simple renderer yourself, a really basic one is not as hard as you might think.
An alternative approach to dealing with this kind of problem might be to pre-process the map data before giving it to the renderer. The idea would be to effectively separate the layers of the map that are static from those that are dynamic and render the dynamic tiles as normal sprites. Just a thought, I'm not sure about the details of how this might work.
I plan to eventually revisit the Tiled API in the next major version of MonoGame.Extended. Don't hold your breath, these things can take a lot of time, but I am paying attention to the feedback and kinds of problems people are experiencing with the existing API.
Since the map data is stored in a XML (or csv) file which runs through the Content Pipeline you can not change it at runtime.
Anyways, in a city builder you usually do not change existing tiles but you place object on top of existing tiles.
![enter image description here][1]please I need some help, this should apparently be something very simple and basic to do, but maybe I'm missing something.
I'm quite newbie to Unity3d, I had no much problem with creating a somewhat flashy 2.D scene (I mean 2D with different layers in Z level), scripts, etc. But I'm having trouble to create a "UI Slider" object: when I create it, it just shows nothing on screen. How can I make it visible? I just need to create a very simple, plain slider whose value can be controlled at runtime by means of a script.
thanks.
Well.. since you give nothing to go on, I suggest that you take a look at a tutorial for the UI:
https://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/using-the-ui-tools
If you have troubles after this tutorial, come back with an example of your problem to make people more willing to sacrifice their time in helping you.
Hope this is somewhat useful
Take a look at the Unity3D docs here.

It should have what you are looking for.
I use MvxImageViewLoader for MvvmCross Xamarin applications.
This component is really great and simplifies the images loading pretty much, but it (at least, out-of-the-box) is pretty basic and most of modern applications require some reacher functionality, for instance, loading/progress images or images nice appearing/transitions (possibly with custom animation).
I see there is DefaultImagePath property, but that's static image, which I can probably use by default, but that's not animated view or something.
So, is there any way to customize/extend the loader behaviour (for default image appearing, images transition (from default to loaded)) etc?
And also I've noticed that the loader caches the image and even if I trigger bound property changing (leaving the image url the same) it does not refresh the image. I guess, "caching" really means caching and so on, but what if I need to change the user icon or something... how can I forse the cache refreshing with the image loader?
Thank you!

No - advanced features like fade-in/fade-out/animated-placeholder display aren't supported within the standard MvvmCross image view, and no-one that I know of has provided any samples or tutorials about how this can be done.
For adding such functionality, you can use normal software techniques - inheritance, aggregation and cut, copy, paste. e.g. you could simply create your own AgatImageView which had the behaviour your app requires based on MvxImageView.cs.
Some examples of creating your own data-bound controls is given in N=18 and N-19 of http://mvvmcross.wordpress.com/
As you already mentioned in upper comments you may use default iOS' UIActivityIndicatorView for showing progress and you should hide the progress in afterImageChangeAction, you can check if UIImageView.Image field is not null, to make sure that the image is loaded.
Regarding the caching, it's not that easy here. By default MvxImageViewLoader relies on MvvmCross framework's implementation of IMvxFileDownloadCache interface. This interface has only one public method RequestLocalFilePath(), so even if you get an instance from IoC container (Mvx.Resolve()) you won't be able to clean-up the existing cache (to do that you need to reset private _entriesByHttpUrl field of MvxFileDownloadCache class).
If you really need this, you have to copy-paste existing MvxFileDownloadCache class and make your tweaks. But I am not sure about your use-cases where you need this. If you download images from the web, the URL of the image is a sort of a key in the cache, so if you need to reload just change the URL.
Maybe you could use some old-school approach like adding GET parameters to the URL: http://mydomain.com/images/myimage.jpg?timestamp=123456. Usually this helps everywhere :-). Although I didn't test it with MvxImageViewLoader, it's just my best guess.
I have an existing component that draws Direct2D content to an ID2D1RenderTarget and I would like to save that drawing to an image file. The questions here, here and here, although they helped me, did not provide a clear answer as how to do it.
My nullth idea was to try the official MSDN method. Unfortunately, it is not available in Win7.
My first idea was to modify the drawing routine to make it accept the RenderTarget as a parameter and use ID2D1Factory::CreateWicBitmapRenderTarget to draw directly into a IWICBitmap, but it turns out to be quite difficult for me (because it would be necessary to modify not only the drawing routine itself, but also the drawing callbacks of all users of that component (the code, written in Delphi, uses Embarcadero's TDirect2DCanvas, and thus did not need to manage all Direct2D resources, like render target or brushes)).
My second idea was to create an ID2D1Bitmap, fill it with what is already drawn using ID2D1Bitmap::CopyFromRenderTarget and then draw that ID2D1Bitmap to a WicBitmapRenderTarget (this is about what was done here). I had the same kind of problems as those who asked the questions I link to: different resources affinities, as briefly explained Kenny Kerr.
So is it possible under Win7 without having to implement my first idea, and how would you do it?
Direct2D 1.1 is supported on Windows 7 if you install the Platform Update. Unfortunately, that doesn't solve your problem without first creating two more of them: 1) it's still pre-release/beta, and 2) it adds another installation dependency for you to worry about.
