I am designing a Xamarin forms app, which pull images from an SQL DB, as array bytes, I then transform it to an image object, which is displayed on the activity without a problem.
But the displayed image is just residing there on the content page without any tools like zooming, rotation...etc. should I design all of these my self?
Many thanks

I am new to Xamarin.Forms and looking for a help on two questions.
I would like take a picture with the camera or download one from a website. Once the image is loaded, to be able to draw on the image with stylus or finger. Once satisfied with the annotation, save the image back. Does anyone know of a tool that I could use to help speed up this dev effort?
Is there a way application can figure out if the image that is being saved is of good quality, meaning not blurry or with disturbance?
Thanks in advance for any suggestions / information.
I am developing an educational app that is made of multiple images. I am also new at coding and XCode. I wanted to know how to get my images so they respond to the gesture similar to the photos on facebook (swiping, min/max zooming, scrolling all on one image). I have the UIImage in UIScrollview.
Can I add all the gestures in UIScrollView or do I have to add each gesture separately? Because the app is made up of multiple png images do I have to connect each image separately or is there a method to implement one code for the entire program?
I am using Storyboard and have minimal coding.
If this information is already out there I would greatly appreciate some direction. I have tried to use "Basic Zooming Using the Pinch Gestures" from the iOS library with little success.
Check out this tutorial.

In this they go over exactly what your wanting, zooming in and out images and swiping. Pretty much you use UIGestureRecognizers. :)
I was wondering if it is possible to use a slider to dynamically load pages with ajax. Basically I wanted the users to be able to slide the bar over to specific months, and these months would be individual pages that would dynamically load content.
Here's a design example
If anyone knows any resources for starters, I would greatly appreciate it!
I tried to find an example for content loading animation (to learn how to implement one in my app). But I couldn't find one.
What I want is: There are 4 listboxes in my mainpage and I want to show a loading animation until the listboxes have completed loading their data.
For example,IMDB application has a loading animation like I want. (You can watch it here http://www.youtube.com/watch?v=AV9BoyGm7Fo)
Any ideas on how to create this?
Thanks
Please refer to these links, as they seem to provide the exact solution to coding this standard loading animation:
