Image Converting and color problem

**electronicboy** · 3rd November 2009, 08:43

Hi all,

I don't found function for used color. And I think I seek all pixel and find unique color. How can I get pixel color fast?

I am sorry, but I don't quite understand, can you restate the question?

In general though, if the Qt supplied function is not good enough for your case, you can do the conversion your self, by iterating through the image - read the QImage documentation on how to access each pixel and how to set pixel values.

Yes there is a method for it - READ the QImage DOCUMENTATION!!

I read and I don't see getPixel :S

"To alter or add a color to an image's color table, use the setColor () function."

But I want to pixel color

reading doesn't mean to look for the function names YOU think are used, but to read the WHOLE class documentation, then you will know how and what you can do with the class!

I forgot to tell I read again and I see pixel function. Also my english is not good. And I am a C#.net developer. I don't use .net. I write the programe in .net and i wrote again in qt. I'm trying to learn qt. Thanks for your's approach and supports.
