I am working on an image editor app having functions like cropping, text rendering, framing etc. I want to implement sketch effect now ie, the photo shall be converted to sketch. I am using Nokia.Graphics.Imaging.Managed library for doing it. It works very fine but only in wp8.
the dll is not compatible for wp7. Please suggest me any free library or any image manipulation method to achieve the functionality.
Thanks in advance
Aviary I've used in the past. Read their terms and conditions if you decide to go with their SDK.

I need to implement some sort of library that allows me to pick (one or multiple), edit, crop, resize, move and apply other effects on user's photos that will be sent to a server later.
I tried to write my own code to do so but it takes much more time and it's quite difficult.
Do you know some libs (open-source or not) that give me the chance to do so?
For editing I know:
Media plugin https://github.com/jamesmontemagno/MediaPlugin
UCrop: https://github.com/NAXAM/ucrop-android-binding
You can bind any library from native to xamarin
Just use SkiaSharp, its free has tons of documentation and is cross-platfrom
I can't find a way to implement a profile pic saving, can somebody help me with example?
I'm capturing an image using MediaPicker (from Xamarin Labs), and then don't know how to crop it or resize to smaller mb size, tried Xamarin Resizer, but can't crop image if it is in wrong format.
Can somebody help me with that? May be there is component that I'm missing?
Take a look at this answer, showing you how you can approach the issue of resizing.
The essence is you can create a Xamarin Forms service and corresponding code that uses native functionality to crop. Native code performs much better - memory requirements, performance etc.
For the exact cropping code you can search SO for iOS and Android native solutions and transform them to Xamarin code
Try asceticcropper
Customizable, predefined masks, works on ios and android
I need to rapidly develop some software that uses a camera as an AV input.
Assuming the drivers are installed for whatever the device that is giving the input I need to be able to capture images and to stream the camera in the winforms window.
I couldn't find a component that I can use, maybe because I don't know the right name for it.
Touchless is under a licence I can't use. If anyone knows of a good compoment/code I can use even if it's for a fee I will appreciate this.
DirectShow.NET library suits the bill here. You can use it to access the webcam directly using the underlaying DirectShow object as in here: http://www.codeproject.com/KB/audio-video/WebcamUsingDirectShowNET.aspx
Also if you consider learning WPF, there is a very neat webcam component here: http://wpfcap.codeplex.com/
It is just like dropping a image control on the worm, but this time in WPF:
Edit: There are also two Winform webcam components as I see now: http://easywebcam.codeplex.com/ and http://www.c-sharpcorner.com/UploadFile/yougerthen/810262008070218AM/8.aspx
This article explains how to access the webcam using Windows Image Aquisition services.
I have a Creative Life CAM Optia AF webcam, the software included in the package is able to control the camera in different ways, like set autofocus to auto or manual, and a bunch of gamma and brightness settings.
I'm capturing the feed with the AForge Computer vision library, and it's working great.
But i would like to be able to set the manual focus from inside my application.
Ive been searching for a tutorial, but come up empty handed.
Can i somehow either disassemble the included software, or is there some way to fetch the traffic / instructions being sent to the device?
Thanks in advance.
If the license agreement that comes with the software allows you to disassemble it, you can do so with Reflector (assuming that it's a .NET application).
How to programatically disable the auto-focus of a webcam?
I think i found a way to do this. But i have never written any C++, that is C++ right?
Thanks :)
I'm trying to let the use crop a selected area from picture in my winforms application and thought to embed the Paint.NET and limit its functions. I understand that Paint.NET API is unavailable..
I'll be happy to get recommendation for another tool i can use to crop images in Winforms application.
Thanx.
It sounds like your requirements are fairly simple, you might be able to roll your own image cropper using a PictureBox and a few mouse events. :)
What paint.net API? There is no paint.net api for using it from other programs.
you can try IpLab to see if it meets your needs. see http://code.google.com/p/iplab/
I would recommend ImageMagick. They have a .NET wrapper for it so it should be usable from C#.
