bitmapimage

I would like to Convert a BitmapImage to a Grayscale BitmapImage: Which I get from a method and therefore - the Width and Height are unknown to me. I have tried looking into options such as WritableBitmapEx and static extension methods but they haven't been helpful to me as I would like the return data type to be a BitmapImage as well as I then need to add it to List. Is this possible in a Windows Phone app using C#? I would really appreciate if someone would shed some light into this. Thank you. The Algorithm is pretty simple: using System.Windows.Media.Imaging; using System.IO; private

UPDATES : Even if i don't retrieve images from cache, i tried to retrieve via Drawable where i stored all the 18 images in the "drawable-mdpi" folder. Still, a blank screen was display. I was able to retrieved images from the server and save the image (.GIF) into the cache. However, when i need to load that image from cache, the image doesn't show up on screen. Here is the codes that does the work: File cacheDir = context.getCacheDir(); File cacheMap = new File(cacheDir, smallMapImageNames.get(i).toString()); if(cacheMap.exists()){ FileInputStream fis = null; try { fis = new FileInputStream

Well, i got this.. cause in my place they request it like that.. Well i have this: //some variables and coments are a possible code.. But i mean i don't know how to do it exactly, i found on internet that to convert R is the byte is in *0.21 with G is *0.71 i guess and blue is * 0.07. I just can use that library java.io.*; and i'm working with BMP format images of 1024 x 768, if you can help me, or you want me to be more specific please tell me. i don't know if i have to add another variables or to take some out, or to modify, please help me. I'm not so new in this language, but i'm not an

I am loading an image from file with this code: BitmapImage BitmapImg = null; BitmapImg = new BitmapImage(); BitmapImg.BeginInit(); BitmapImg.UriSource = new Uri(imagePath); BitmapImg.CacheOption = BitmapCacheOption.OnLoad; BitmapImg.CreateOptions = BitmapCreateOptions.IgnoreImageCache; BitmapImg.EndInit(); It works as expected except for the fact that no matter what kind of image I'm loading (24bit RGB, 8bit grey, 12bit grey,...), after .EndInit() the BitmapImage always has as Format bgr32. I know there have been discussions on the net, but I have not found any solution for this problem. Does

The following xaml works ok inside a Window : <Border Width="45" Height="55" CornerRadius="10" > <Border.Background> <ImageBrush> <ImageBrush.ImageSource> <CroppedBitmap Source="profile.jpg" SourceRect="0 0 45 55"/> </ImageBrush.ImageSource> </ImageBrush> </Border.Background> </Border> But when I use the equivalent code in a DataTemplate I get the following error in run-time: Failed object initialization (ISupportInitialize.EndInit). 'Source' property is not set. Error at object 'System.Windows.Media.Imaging.CroppedBitmap' in markup file. Inner Exception: {"'Source' property is not set."} The
