When I am having an object of any size (in this case it will be 300px x 300 px), I need a tool like a brush. For example, I want first pixel on the top left to be black, second pixel on the top left - red, but what I am calling a pixel is not actually a pixel, it is a pixel-sized vector.
Color Eyedropper Tool [Sample colors, and apply them to objects], which is used in CorelDraw applies these colors to the objects as a whole - and in this case it is an object of a 300x300 size. Can I apply my color to one pixel only - like I said - first on the top left?
CorelDraw was only an example of a software used. Please, give me another soft to make it easier for me to work with desired colors. (Corel PaintShop Pro X5 maybe?)
