Aleksei Androsov 6555f9bee8 Fix photo orientation from ImagePickerIOS
Summary:
Original PR: https://github.com/facebook/react-native/pull/12249

ImagePickerIOS saves photos to ImageStoreManager without meta information. So photo has wrong orientation.

**Test plan**
1. Take the 2 photos (in landspape and portrait orientation) with this code:
```
ImagePickerIOS.openCameraDialog(
  {},
  (uri) => CameraRoll.saveToCameraRoll(uri),
  () => {}
);
```
2. Ensure that photos in Photos app have right orientation.
Closes https://github.com/facebook/react-native/pull/15060

Pieter De Baets e1577df1fd Move all header imports to "<React/..>"
Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.

Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

aleclarsoniv bee118096b Add Image resizeMode center to iOS
Summary:
Addresses this comment: https://github.com/facebook/react-native/issues/2296#issuecomment-232446493

This pull request adds the `center` value to `ImageResizeMode`.
When set, it will center the image within its frame.
If the image is larger than its frame, the image is downscaled while maintaining its aspect ratio.
That is how the Android implementation works, too.

Sorry, don't have time to write tests. 😢

Any reviewers should make sure `RCTTargetRect` returns the correct value when:
- the image is smaller than its frame (ie: no downscaling needed)
- the image is larger than its frame (should be downscaled to avoid clipping)

Janic Duplessis 4c83237511 Add Image resizeMode repeat on iOS
Summary:
This adds a new resize mode for iOS 'repeat' that tiles the image over it's frame. This allow to easily create a view with a repeating background pattern which there is no way to do at the moment without including a bunch of different sized assets.

I'm not 100% sure it should be a resizeMode or a separate prop but I went with resizeMode since it made more sense to me and the are not really any use cases where we'd want to use this with another resizeMode other than 'stretch'.

**Test plan**

Tested mainly by adding a UIExplorer example, also tested that changing the resizeMode prop from and to 'repeat' worked properly.

I'd like to implement this on Android too but it is a bit trickier since Fresco's ImageView doesn't support image tiling and would require submitting a PR there too :(

Nick Lockwood 37f4ec6e16 Removed placeholder image logic
Summary: To prevent layout popping, when inserting images inside text we would render a blank placeholder image while the real image was loading. It turns out that this isn't necessary, as we can just specify the size of the image without having an actual image to display.

Summary:Images cropped using the ImageEditor were always given an alpha channel, even if opaque.

Summary:
public

Previously, `<Image>` elements embedded inside `<Text>` ignored all style attributes and props apart from `source`. Now, the `width`, `height` and `resizeMode` styles are observed. I've also added a transparent placeholder to be displayed while the image is loading, to prevent the layout from changing after the image has loaded.

Nick Lockwood 718cd7953f Added getImageSize method
Summary:
public

This diff adds a `getSize()` method to `Image` to retrieve the width and height of an image prior to displaying it. This is useful when working with images from uncontrolled sources, and has been a much-requested feature.

In order to retrieve the image dimensions, the image may first need to be loaded or downloaded, after which it will be cached. This means that in principle you could use this method to preload images, however it is not optimized for that purpose, and may in future be implemented in a way that does not fully load/download the image data.

A fully supported way to preload images will be provided in a future diff.

The API (separate success and failure callbacks) is far from ideal, but until we agree on a unified standard, this was the most conventional way I could think of to implement it. If it returned a promise or something similar, it would be unique among all such APIS in the framework.

Please note that this has been a long time coming, in part due to much bikeshedding about what the API should look like, so while it's not unlikely that the API may change in future, I think having *some* way to do this is better than waiting until we can define the "perfect" way.

Nick Lockwood b672294858 Added RCTImageSource
Summary:
public

The +[RCTConvert UIImage:] function, while convenient, is inherently limited by being synchronous, which means that it cannot be used to load remote images, and may not be efficient for local images either. It's also unable to access the bridge, which means that it cannot take advantage of the modular image-loading pipeline.

This diff introduces a new RCTImageSource class which can be used to pass image source objects over the bridge and defer loading until later.

I've also added automatic application of the `resolveAssetSource()` function based on prop type, and fixed up the image logic in NavigatorIOS and TabBarIOS.

Nick Lockwood 0fe074acbd Removed all calls to [UIImage imageWithData:] on a background thread
Summary: public

I had previously assumed (based on past experience and common wisdom) that `[UIImage imageWithData:]` was safe to call concurrently and/or off the main thread, but it seems that may not be the case (see https://github.com/AFNetworking/AFNetworking/pull/2815).

This diff replaces `[UIImage imageWithData:]` with ImageIO-based decoding wherever possible, and ensures that it is called on the main thread wherever that's not possible/convenient.

I've also serialized access to the `NSURLCache` inside `RCTImageLoader`, which was causing a separate-but-similar crash when loading images.

Matthieu Achard 2b657003b7 RTCImageStoreManager uses NSData instead of UIImage
Summary: Hi,

I'm currently building an app that changes metadata, does some resizes, maybe watermarking ...etc. I want to use RCTImageStoreManager to store the original image in memory and allow me to command different modifications from javascript as it gives me more flexibility. As RCTImageEditingManager does for example.

But currently the RTCImageStoreManager uses UIImage to store the image, the problem is that UIImage losses metadata.
So i suggest we change it to NSData.

Additionally I added a method to remove an image from the store.

Yusef Napora 2fe1ac2a83 [Image] Fix invalid CGContext when one dimension of destination Image size == 0
Summary:
Addresses #1534

When an image has a known width, but a height of 0 (which can happen if `flex: 1` is set on the `Image` element), `RCTDownloadManager` attempts to scale it to an invalid size, which results in a `NULL` `CGContextRef` and some scary warnings from UIKit:

```
 <Error>: CGContextTranslateCTM: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context  and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.
```

This adds a check for zero width or height to the `RCTClipRect` function.  If either dimension is zero, it is calculated based on the aspect ratio of the source image.  This ensures that we don't try to create an invalid `CGContextRef`, and that images with an unknown dimension are still scaled, blended, etc.
