Feature request: load to Bitmap instead of ImageViewAsync

FFImageLoading is pretty fantastic. I have a use case where I’m making Android notifications that require Bitmaps. Could you make an overload of Into that loads into Bitmaps or something similar instead of ImageViewAsyncs?

I did try making a SideEffectTransformation that would copy the bitmap in directly, but immediately worried that caching would prevent future notifications with the same image from displaying properly.

And I tried loading into an ImageViewAsync and doing Draw to draw into a bitmap, but the resulting bitmap was transparent even with FadeAnimation(false).

Thanks for all your hard work!

You have mixed different FFImageLoading versions in your projects, also remove all bin / obj folders

And here is the fetchBitmap method:

async Task<Android.Graphics.Bitmap> fetchBitmap(string imageUri) { try { var draw = await ImageService.Instance.LoadUrl(imageUri).DownSample().AsBitmapDrawableAsync(); return draw.Bitmap; } catch (Exception e) { Debug.WriteLine($“Bitmap exception: {e.Message}”); return null; } }

Currently, you should use:

• await ImageService.Instance.LoadFile(xxx).DownSample(width: xxx).AsBitmapDrawableAsync() for Android
• await ImageService.Instance.LoadFile(xxx).DownSample(width: xxx).AsUIImageAsync() for iOS
• await ImageService.Instance.LoadFile(xxx).DownSample(width: xxx).AsBitmapDrawableAsync() for Windows (yeah I noticed bad naming, we should change it in future)

Please mind that on Androidyou should call SetNoLongerDisplayed method if drawable is no longer displayed when not using it with ImageViewAsync (which does it automatically)
