image comparison, pixel by pixel? - CodeGuru
2009年1月19日 · For example, an image made of horizontal lines, alternatively black and white, and a copy of it, translated vertically by 1 pixels, would result in a pixel per pixel comparison different by a 100% value, total unlikeliness, even if it is the same image, just translated!
Getting Access to Pixel Information from Bitmap Files
2011年3月23日 · Primarily because I don't have a a good understanding of the GDI functions. At one point I had a hard time capturing and having access to the pixels on the desktop. I eventually found a solution here. What I want to do now is use image comparison to determine the state change of my computer while it is running various apps.
RC File, Dialog Size - CodeGuru
2008年1月29日 · Setting the size of a dialog to 100,100 results in an actual pixel size of about 150,163 Is there anyway to set the size based on pixels? Currently I am using a cheap fix, using OnInitDialog to call: SetWindowPos(NULL, 0, 0, 100, 100, SWP_NOMOVE); This works fine, but I'd really like to know of other possible options. Thanks for your time.
CArrayEx for 2D arrays - forums.codeguru.com
2001年10月30日 · Hi, I am using CArrayEx to manipulate 2 dimensional arrays which will be of variable size (dynamic). More specifically after an image is displayed onto the main window, I go through that image pixel by pixel, storing specific information into …
Visual Basic .Net 16-bit grayscale BMP - CodeGuru
2003年11月1日 · The trouble there is (I believe) the stream needs to represent an actual Bitmap. That is, the constructor tries to read formatting information from the stream, rather than just pixel values. I need to be able to display non-formatted data. I guess an equivalent question is how can I convert from 8-bit grayscale into RGB?

[RESOLVED] Draw Image Using 2D Byte Array
2013年2月8日 · Each row contains 3 bytes per pixel, plus up to 3 unused bytes in order to make the number of bytes in a row a multiple of 4. Your variable pitch would be the number of bytes it takes to store one row of the bitmap, though you are using 32 bits per pixel instead of 24. The first byte of each pixel is the blue component.

Reading screen pixels fast - CodeGuru
2001年10月22日 · Reading a screen pixel while in full screen mode is likely not going to work since you do not "own" a handle to the DirectX surfaces. Getting a DC from the desktop (NULL) to try and read a pixel from the fulls screen DirectX session will likely not work as well or at least not work on all systems reliably to try and read a hardware pixel.
GDI+ and 16-bit grayscale images - CodeGuru
2003年3月18日 · I try to clarify a little bit my needs: first of all, I would like to work with 16-bit Bitmaps because I have input images that are 16-bit-per-pixel grayscale. I'm using a BYTE buffer and I'm concerned with Big vs. Little endian because the Bitmap constructor requires a BYTE buffer even if you specify "PixelFormat16bppGrayScale" or ...
