Displaying pixel values
-
Hi, i was wondering is it is possible to pull out the pixels values and display it out. (eg. pixel 1 ->[2,25,125])
GetPixel will do this if you have only a few pixels to do. For speed, if you want them all, you should read my image processing articles. Christian Graus - Microsoft MVP - C++

how many pointers do i need? 1 or 3? sorry abt that i just took up C# because of my project requirements i am rather confused now thanxz in advace:confused:

i have only learnt Java basic however my supervisor wants us to pick us C# to do this project. i am confused as to i have to pull out the red, green and blue values for all the pixels of the whole picture so i was thinking maybe i would need three pointers one for each color. i have been looking at all 6 of your image processing articles for the pass 1 month++.

The byte array that is returned contains a series of bytes, with three for each pixel, blue, green, then red. Why do you need to pull all the pixels out ? What will you do with them ?

i need to display the pixel values inorder to see clearly how the values changes each function.

You're showing ALL The pixel values ? Must be a small bitmap, perhaps GetPixel is all you need. Christian Graus - Microsoft MVP - C++

erm it is a big one but will be cropping out a certain part of the picture to see the values.

Same deal - if you only want to pull out a small number of values, you may decide to use getpixel, to simplify the code. Christian Graus - Microsoft MVP - C++
