I'm using an image as my background in my project in hand in flutter and to get a nice look, i have a applied a nice blur effect and white overlay with blendmode set to overlay to get a brightness effect. It works fine in my phone but I have tried phones with lower hardware and it lags horribly. I had a similar problem in my web project and it was simply solved by blurring the image once in canvas and getting it as an base64 dataUrl, in flutter though couldn't achieve this.
Can anyone help me with it?
I am developing a project (kinda like CamScanner) where I take an image and on the fly crop it and edit it and save it to my device memory. I chose to do it in xamarin forms because of 1 source maintenance. I have managed to take the image using Xam.Plugin.Media and crop that image using ImageCropper.Forms plugins. Now, I cant seem to find any good plugins that can edit my image (Filters like Black and White, Magic Color, Grayscale). Can anyone guide me to choose which plugin is the best there is for the filter? I am focusing mainly on Android and iOS at the moment.
Thanks in advance
As of today, there is no plugin available to apply color filters for Xamarin.Forms. The closest thing would be using SkiaSharp Color Filters and define you own Color Matrices, which is not quite user friendly.

I have implemented live camera and using Android text recognition and when I touch the bounding box overlay, text to speech works but in Universal windows, app cant get any documentation can anyone help how to implement in live camera OCR?
APIs from Windows.Media.Ocr namespace can extract text and text layout information from images. It’s designed to handle various types of images. For camera, you could capture images from the camera for recognition. You could get VideoFrame from camera and convert to image.
More details about how to implement OCR in UWP app please reference this sample. The scenario 2 provides how to capture image from camera and extract text.
More details about MediaCapture in UWP app please reference this tutorial.
For text to speech feature please try to reference this article and this sample.
If you want more additional features than Windows.Media.Ocr namespace, I recommend you to use Microsoft Cognitive Services. Check the Analyze video in near real-time section for more details.
I have a own android renderer of Image for rounded image on Xamarin.forms.
But it's opacity property is not working.
When I set it's value, image disappears.
(iOS & Android under Lollipop, works fine)
My renderer is quite similar with this

This package is also not working when I set opacity.
It's really hard to make well working circular image.
Could you help me?
Thanks.
