    http://oi63.tinypic.com/2yo74gl.jpg,the original image have 9400x7500 pixels size
    I explain, I made a map of a world invented in paint.net and then extracted reliefs that made VT 45 and put them there, but all have lost quality and it is impossible to work with them with paint, you should use the https: // visibleearth .nasa.gov / view.php? id = 73934 and make the collage in it and then transform it as VT 45 did in paint format, in this I would ask someone to do it, since I do not know, another option would be a way to cut and paste the relief images without losing quality, to see if they can help me

    To keep it from losing quality, never save it as a .jpg, save it as a .png instead, as that uses lossless compression. (Also, rotating something at an angle other than a multiple of 90 degrees can cause loss of quality of the part rotated)

    I dont know why this appear when I try to open the png file in paint
    Paint cannot read this file. This is not a valid bitmap file, or its format is not currently supported
