    <p>I have already used the LockBits and UnlockBits functions and takes the byte array of a Image into a 1D array. (considering only the black and white/binarized images)</p> <p>Is there any way of taking it to a 2D array (of the size image height and width)? so i can wirte the array into a ".txt" file and view it?</p> <p>The code i have used to take the image into 1D array is as below:</p> <pre><code>Public void function(Bitmap image){ { byte[] arr1D; byte[] arr2D; BitmapData data = image.LockBits(new Rectangle(0, 0, img_w, img_h), ImageLockMode.ReadOnly, image.PixelFormat); try { IntPtr ptr = data.Scan0; int bytes = Math.Abs(data.Stride) * image.Height; byte[] rgbValues = new byte[bytes]; arr1D = rgbValues; Marshal.Copy(ptr, rgbValues, 0, bytes); } finally { image.UnlockBits(data); } } </code></pre> <p>Since the image is binary, the values of the Byte array is from only 255 and 0.</p> <p>Instead of extracting the entire image to a 1D array, is there any method/code where i can extract pixel row by row to a 2D array, Where i can write it to a text file and see later on?</p> <p><em>Programming Language : <strong>C#</em></strong></p> <p>example: (if the value 255 is replaced with 1)</p> <p><em>result output:</em> 1D array: (6px X 6px image)</p> <pre><code>0 0 1 1 0 0 0 0 1 1 0 0 1 1 1 1 1 1 1 1 1 1 1 1 0 0 1 1 0 0 0 0 1 1 0 0 </code></pre> <p><em>expected output:</em> 2D array: (6px X 6px image)</p> <pre><code>0 0 1 1 0 0 0 0 1 1 0 0 1 1 1 1 1 1 1 1 1 1 1 1 0 0 1 1 0 0 0 0 1 1 0 0 </code></pre> <p><strong>Can someone please help me with the code for it in C#?</strong></p>

    1. COYou can write a 1D array to a file in N-dimensions; it's just a matter of viewing them. Write W entries the first line, then add a newline, then write W entries the next line and so on until H lines are written. The total number of written entries is W*H (or the size of the 1D array).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
