Blank screen in rotation

[benkhachouch]

Hello.Congratulations for your application. We have thé same idéa for a social network . It réalised my app with firebase ane s.

In image details During the rotation of the mobile there is à blank screen and image make long time to display.why?

Ôther thing

For displaying correcty thé imâge and text without jumping (image upload) I register ratio in firebase and make à quad with image dimensions

When you rotate your device a Context Loss is triggered. This means the image texture is lost and needs to be recreated.

If the image is too large it will take longer for it to be recreated. I suggest to keep images in a resolution no larger than 2000x2000 px.

I don't understand your second question, can you explain it with more detail or provide an screenshot of what are you having issues with?

To avoid the text jumping While waiting for the loading of the image, I suggest to do that.(like facebook)

var bigImage:ImageLoader = new ImageLoader(); var group:LayoutGroup=new LayoutGroup; group.layoutData = new VerticalLayoutData(0, NaN); var quad:Quad=new Quad(stage.stageWidth,stage.stageWidth/_data.selectedImage.containerRatio,0xCCCCCC); group.addChild(quad); //bigImage.layoutData = new VerticalLayoutData(100, NaN); bigImage.width=stage.stageWidth bigImage.minWidth = bigImage.minHeight = 50; bigImage.source = Constants.FIREBASE_STORAGE_URL + formatUrl(_data.selectedImage.url) + "?alt=media"; var cache:TextureCache = new TextureCache(); bigImage.textureCache=cache group.addChild(bigImage); addChild(group)

Here are the 2 screens: Before loading the image and then after

This is ok but i have a problem with the rotation the image no fill the stage (width)

None of your pictures got sent to the GitHub thread.

Can you log in to GitHub and manually attach them?

[benkhachouch]

i have uploaded my pictures.

[agentphantom]

I think I got what you mean.

When you enter the screen the text shifts down after the image has been completely downloaded.

This can be avoided by presetting a min height as you have suggested in your code. I was aware of this issue while I was designing the app. My idea was to always show the full height of the image but since we don't know it we let the layout to automatically adjust itself.

I have a couple of ideas to fix this behavior, I will update this post and the code later today with a fix.

[agentphantom]

I have pushed some changes that have fixed this issue.

I have implemented your idea and enhanced it a bit:

When you upload an image, it will also save its width and height.

Once you want to see a picture a ratio will be calculated for the initial shown height.

When the picture is loading, a background image is shown (instead of a Quad), since this background image is embedded into the app it will show instantly. You can find this image on assets/icons/loading.png

This background image is also shown during a context loss, it gives the impression to the user that the image is loading again (which actually happens).

I also added a TextureCache, I noticed the texture gets restored a bit faster with it.

Exactly what il made (without quad). Ôther issue in Chatscreen the input would is set to wordwrap.the user dont see all his text.

Other thing can you implément déléte option For sélected messages? A delete button then is added.

I tested your solution. There is a size offset between the background image and the loaded image. I keep my solution who working

I have a good new. I solved the problem of rotation and reaction time for loading.

The idea is not to use an imageLoader but an Image. We load the file. Once finished, we retrieve the bitmapData and we create the Image with Texture.fromBitmapData

The differences are enormous. No reloading after a rotation for example. I will put my code quickly

[benkhachouch]

essentially..

var loader:Loader=new Loader; loader.load(new URLRequest(Constants.FIREBASE_STORAGE_URL + formatUrl(_data.selectedImage.url) + "?alt=media")); loader.contentLoaderInfo.addEventListener(flash.events.Event.COMPLETE,function(e:flash.events.Event):void{ var loader:Loader=(e.currentTarget as LoaderInfo).loader var bitmap:Bitmap=loader.content as Bitmap; donnees=bitmap.bitmapData; bigImage = new Image(Texture.fromBitmapData(donnees)) bigImage.width=bigImageGroup.width bigImage.height=bigImageGroup.height bigImageGroup.addChild(bigImage) })

donnees is a private variable who dispose() when leaving screen

[agentphantom]

Thank you!

I will implement it and commit the changes later today.
