writeablebitmap

I am trying to port my app in windows phone . i have to upload an image on server So it is in small Size For uploading i have done this thing in Widows Successfully but problem is when i failed in it .. here is my code for windows App public void CompressImage(int i, int j) { bmp1.SetPixel(j, i, Color.FromArgb(bmp.GetPixel(j, i).R, bmp.GetPixel(j, i).G, bmp.GetPixel(j, i).B)); } private void bLoadImage_Click(object sender, EventArgs e) { OpenFileDialog file = new OpenFileDialog(); if (file.ShowDialog() == DialogResult.OK) { pictureBox1.Image = new Bitmap(file.FileName); } } private void

The constructor of WriteableBitmap class with Windows 8 only takes two arguments: the height and the width of this object. Meanwhile with Silverlight it accepts a BitmapImage object as argument. (Verified on MSDN : WriteableBitmap.WriteableBitmap constructor ) I would like to load this BitmapImage because I'm trying to blur an image which already exists on my Assets folder. Thanks for your help, I succeed to blur my image. Here is the sample in order to link the BitmapImage into the WriteableBitmap object : BitmapImage bi = new BitmapImage(new Uri(filename, UriKind.RelativeOrAbsolute));

I'm writing an application in WPF (C#) which does long operations on a collection of Bitmaps. To keep my application responsive, I decided to use another thread to perform the operations on bitmaps and report progress on a progressbar in main UI thread. I thought BackgroundWorker would do anything for me, but looks like it won't be that easy. I have the following code: public class ImageProcessor { public Collection<WriteableBitmap> Pictures { get; private set; } private BackgroundWorker _worker = new BackgroundWorker(); public ImageProcessor() { _worker.DoWork += DoWork; } public void

Do you know any library that provides methods to draw simple shapes (lines and optionally other shapes) using WPF WriteableBitmap and ideally BackBuffer? I know that there is a WriteableBitmapEx project for silverlight but is there WPF equivalent? adrin I guess here is the answer to my question :) _plotBitmap.Lock(); var b = new Bitmap(_plotBitmap.PixelWidth, _plotBitmap.PixelHeight, _plotBitmap.BackBufferStride, System.Drawing.Imaging.PixelFormat.Format24bppRgb, _plotBitmap.BackBuffer); using(var bitmapGraphics = System.Drawing.Graphics.FromImage(b)) { bitmapGraphics.SmoothingMode =

I am working on a silverlight application, where all my icons are PNGs. The color of all these icons is black, or rather black to gray, depending on the alpha value. Every PNG has a transparent background. Inside my application, I want to do a pixel by pixel color change from black or gray, let's say to red (before black) or light red (before gray). Walking through the bytes of every pixel, I recognized, that every full black pixel has an alpha value of 255. Those, who are gray, have an an alpha value between 1 and 254. An alpha value of 0 seem to be transparent. The RGB values are all 0 for

I am trying to find out how to use FJCore to encode a WriteableBitmap to a jpeg. I understand that WriteableBitmap provides the raw pixels but I am not sure how to convert it to the format that FJCore expects for its JpegEncoder method. JpegEncoder has two overloads, one takes a FluxJpeg.Core.Image and the other takes in a DecodedJpeg. I was trying to create a FluxJpeg.Core.Image but it expects a byte[][,] for the image data. byte[n][x,y] where x is width and y is height but I don't know what n should be. I thought that n should be 4 since that would correspond to the argb info encoded in each

I have: WriteableBitmap bmp; I basicly want to save it into a file on the disk like the following: C:\bmp.png I read some forums which mentions to read: bmp.Pixels and save those pixels into a Bitmap then use Bitmap.SaveImage() function. However, I can't access any Pixels . Apperantly my WriteableBitmap does not have any property named Pixels . I use .NET Framework 4.0. Use your WriteableBitmap's clone and use this function as below: CreateThumbnail(filename, _frontBitmap.Clone()); ... void CreateThumbnail(string filename, BitmapSource image5) { if (filename != string.Empty) { using
