bmp

i got a question for reading an bmp image. How can i get the pixel value(R, G, B values) in an bmp image? Can anyone help me using the C programming language? The easy way would be to find a good image manipulation library for your chosen platform and use that. Linux ImLib / GDK-Pixbuf (Gnome/GTK) / QT Image (KDE/Qt) should be able to do what you need. Windows I'm not familiar with the appropriate system library, but an MSDN Search for "Bitmap" is probably a good place to start. Mac OSX Cocoa has some image manipulation capabilities, see this article . The hard way would be to open the file

is there anyway that i can convert a png to a bmp in c# i want to download a image then convert it to a bmp then set it as the desktop background i have the downloading bit and the background bit done i just need to convert the png to a bmp Image Dummy = Image.FromFile("image.png"); Dummy.Save("image.bmp", ImageFormat.Bmp); Certainly. You'd want to load up a Bitmap object with your png: Bitmap myBitmap = new Bitmap("mypng.png"); Then save it: myBitmap.Save("mybmp.bmp", System.Drawing.Imaging.ImageFormat.Bmp); Have you tried this? Image imgFile = Image.FromFile(aFileName); imgFile .Save

I have a Bitmap in memory and I need to save it in a bmp file (using the bmp file format ). Is there any way to do it on Android ? (I read a lot of post suggesting to use the png format - which is loss-less - but, that's not what I need: I really need the bmp format ). I already have some code to save it in jpeg or png using the Bitmap.compress method : /** * Save data to file using format. * When format is null : the bitmap will be saved in bmp format **/ public void writeBitmapToFile(Bitmap data, File file, Bitmap.CompressFormat format) { FileOutputStream os = null; try { os = new

Why are BMP images stored upside down and zero-padded so they are four-byte aligned? Here's a quote from Petzold: So, in DIBs, the bottom row of the image is the first row of the file, and the top row of the image is the last row in the file. This is called a bottom-up organization. Because this organization is counterintuitive, you may ask why it's done this way. Well, it all goes back to the OS/2 Presentation Manager. Someone at IBM decided that all coordinate systems in PM—including those for windows, graphics, and bitmaps—should be consistent. This provoked a debate: Most people, including

How can I convert a BITMAP in byte array format to JPEG format using .net 2.0? What type of byte[] do you mean? The raw file-stream data? In which case, how about something like (using System.Drawing.dll in a client application): using(Image img = Image.FromFile("foo.bmp")) { img.Save("foo.jpg", ImageFormat.Jpeg); } Or use FromStream with a new MemoryStream(arr) if you really do have a byte[] : byte[] raw = ...todo // File.ReadAllBytes("foo.bmp"); using(Image img = Image.FromStream(new MemoryStream(raw))) { img.Save("foo.jpg", ImageFormat.Jpeg); } If it is just a buffer of raw pixel data, and
