Quick CameraRoll Question
My app needs to be able to import an image that the user selects from the
cameraroll. But my app is not capable of handling a video or a PNG, only
JPG files. Is there a way when you browse the cameraroll, that you can
specify it to only show the JPG images that the user has, and not all the
various image types that they may have??
Thanks!

Jan,
thanks for the hint on the native methods! I indeed missed that and used
the old encoder from the AS3CoreLib!
Sounds promising; I'll give it a try. And probably later will dive into
workers also; another option I ignored so far ;-)
Regards
Hans

Quick update:
I had a short email exchange with Distriqt, and the actual situation of
their "IMAGE" ANE (JPG/PNG decoder/encoder) is this:
"There is no performance gains on Windows or macOS for the image ANE
currently.
It is one of the ANEs on our agenda for this year."
Actually I'm mostly intersted in a Windows and OSx version; that's why I
had checked with Distriqt and that's what there statement is addressing.

Re: Quick CameraRoll Question
Posted by "Erik J. Thomas" <er...@linqto.com>.
Yes, there is a better, faster way of encoding/decoding bitmaps using an ANE:
https://airnativeextensions.com/extension/com.distriqt.Image <https://airnativeextensions.com/extension/com.distriqt.Image> - This Image extension allows developers to encode and decode image data with native code. The extension provides the ability to encode/decode, save/load image data both synchronously and asynchronously. Using native functionality to encode image data will significantly increase the speed of saving image data to the device.
There are probably others out there. While I haven't used this particular ANE, I have been using the QR Scanner, Push Notifications, Fingerprint Auth, Native Dialogs, Native StageView, and PDF Viewer ANEs from Distriqt and can vouch they are well supported, work as advertised, are kept up to date with every new OS version, and work across iOS and Android with the APIs.
Another approach we use for one app where we need to save the image to an asset server, we upload the data and do the conversions on our java-based web service hosted on super fast hardware and offload that job from the mobile device and return the URL and display that in the app. It's actually faster that encoding on older phones and this app shares captured photos among all connected users so it makes sense not to bother encoding on the device.

Re: Quick CameraRoll Question
Posted by bilbosax <wa...@comcast.net>.
After a little testing, I may just be in luck. I "assumed" that all file
types that displays in the Photos app on iOS would show up in the
cameraRoll, but unless I am mistaken, I don't think they necessarily do.
cameraRoll.browseForImage() appears to show only images, removing video
files. I guess it's possible I just didn't see my test video, and I don't
know if there is a browseForVideo() method if what your app needs is videos,
but right now, I am not seeing any videos in the list of media. Same for
Android. So that takes care of the video problem for me.
And, the way that the image data gets sent to AIR, it appears my app does
not really care whether it is JPEG or PNG. Both seem to work with the
bitmap and bitmapdata objects that i work with.
So I might be missing something, but I think I am good to go!!!
Thanks for the input Erik!

Re: Quick CameraRoll Question
Posted by "Erik J. Thomas" <er...@linqto.com>.
Unfortunately, the flash CameraRoll (which is truly great) doesn't provide what you need in this scenario.
I think you have three options:
1. Respond to the "select" event and if the file is unsupported, pop a message and allow them to select another file. Make sure your app UI preps the user about what image types are supported. However, this is a sticky wicket when only supporting one image type when all other apps in the world support at least png and jpg, and often bmp, etc.
2. Change your app to support png format which is a really good idea anyway, and use #1 if they select a video.
3. Use an ANE that supports a filter.
I do not see any option in flash CameraRoll to establish a file type filter. But consider that mobile apps are about easy stuff. So supporting both png and jpeg at a minimum will increase the value of your app by a lot. If you need any help using the 2d library to manipulate jpg and png, I can help. I've written a lot of raw bitmap manipulation logic through the years, both jpg and png. In fact, if you really need to only support jpg, you can convert your png to a jpg, though it takes a little time on a mobile device, measured in seconds if it's large.
Cheers,
Erik

My app needs to be able to import an image that the user selects from the
cameraroll. But my app is not capable of handling a video or a PNG, only
JPG files. Is there a way when you browse the cameraroll, that you can
specify it to only show the JPG images that the user has, and not all the
various image types that they may have??
Thanks!
