pixels

I have an array of int pixels in my C# program and I want to convert it into an image. The problem is I am converting Java source code for a program into equivalent C# code. In java the line reads which displays the array of int pixels into image: Image output = createImage(new MemoryImageSource(width, height, orig, 0, width)); can someone tell me the C# equivalent? Here orig is the array of int pixels. I searched the Bitmap class and there is a method called SetPixel but the problem is it takes a x,y coordinate number. But what I have in my code is an array of int pixels. Another weird thing

I'm trying to use the Mean Shift Function from OpenCV inside a program called Processing, which is a language based on Java. So far, I know that the function requires two mat and two double, [ pyrMeanShiftFiltering( Mat, Mat, Double, Double) ] and the mat needs to be 8 bits and 3 channels. But, when I run it, it only seems to work for the upper 3/4 th of the image and cuts out the rest. Does anyone know how to get this function to run on the whole image? sample image: cat.jpg import gab.opencv.*; import java.nio.*; import org.opencv.imgproc.Imgproc; import org.opencv.core.Mat; import org

What is difference in between the b.Height and b.Width properties and the b.HorizontalResolution and b.VerticalResolution in C#? Bitmap b = new Bitmap(@"foo.bmp"); For my sample, Height = 65, Width = 375, HorizontalResolution = VerticalResolution = 150.01239 . MSDN says height and width are in pixels, but the HorizontalResolution and the VerticalResolution are pixel per inch. So, does that mean that is the dpi at which this image was scanned from a scanner for example? Or is this something else? The context of the question is the following: I would like to scan a signature and show in it on an

How can I determine the width in pixels for a canvas (which has a certain width)? I have a bitmap in an AnimatedImage control, and I know the bitmap's width in pixels, and I want to scale the bitmap so that it horizontally fits exactly the canvas. How can i determine this scale? Note: I do not need to use RenderTargetBitmap, because the bitmap is already loaded. In WPF units are device independent. The formula to figure out the actual pixel size of a unit is: Pixels per WPF Unit = ConstantWPFUnit size * monitor DPI; Size of your element in pixels = Pixels per WPF Unit * MyElement.ActualWidth

Is it bad in terms of compatibility to use pixel numbers in CSS instead of percentages? How about lower resolutions? Is it okay to work with them in ranges of 1-100? This is a difficult question, because the answer mostly depends on your situation. Pixels are not that bad, I mostly use them too. (Sometimes even for font sizes.) I usually fix the outer block element of the layout by a given size (pixels with fixed-width layouts, and percentages with fluid layouts), and on the inside elements I usually set percentages whenever possible. There are some elements which simply can't be styled with

I'm wondering if that's possible: I got a c# application with something like a display consisting of about 11000 circles drawn on the Form. What I want to achieve is to be able to draw text on that display, but not using the "real" pixels, but using the circles (rectangles) drawn on the form as pixels. Edit 1: When drawing text in c#, you would i.e. use something like Graphics.DrawString(...) , giving the method a rectangle (so coordinates) in which the text should be drawn in. That text then is drawn in that rectangle using the screen pixels. What I want to do is draw text as well but not
