How can I know the value of the pixel with coordinates (X, Y) and a graphical object?

do you mean RGB Value from 1 Pixel ? what do you want to do with that Value ?

[Eugene Lutsenko]

May be. Yet it would be desirable to be able to read the pixel values ​​for the coordinates in a graphic object to analyze it, for example to draw contours do fill and the like.

if i draw a circle and save it as Bitmap. do you want to fill circle of Bitmap ?

[Eugene Lutsenko]

In general yes, but only a circle, and any figure formed by a closed line. Moreover, the line color of the shape itself and the background mogut change and we must first select the path to a high gradient (contrast), color and brightness, and then later fill.
