Question

I’ve been looking around on Google for quite some time and cannot seem to find a solution to my problem.

The problem is with painting a bitmap onto a panel. For some strange reason the entire bitmap seems to have an offset towards the upper-left of the panel.Which makes it confusing when building the map. As an extra note the bitmap was being painted on a panel larger than itself. (e.g. bitmap.dimensions == 64×64 and panel.dimensions == 512×512).

    private void redrawCityPanel()
    {
        Image cityImage = this.cityBitmap;

        Graphics panel_CityGraphics = this.panel_City.CreateGraphics();
        panel_CityGraphics.Clear(this.panel_City.BackColor);
        panel_CityGraphics.InterpolationMode = InterpolationMode.NearestNeighbor;
        panel_CityGraphics.DrawImage(cityImage, panel_City.DisplayRectangle);
    }

Sorry about the confusion. I would post images but I haven’t earned enough points.

All I needed to do was set the pixel offset mode.

private void redrawCityPanel()
{
    Image cityImage = this.cityBitmap;

    Graphics panel_CityGraphics = this.panel_City.CreateGraphics();
    panel_CityGraphics.Clear(this.panel_City.BackColor);
    panel_CityGraphics.InterpolationMode = InterpolationMode.NearestNeighbor;

    panel_CityGraphics.PixelOffsetMode = PixelOffsetMode.Half; //Added

    panel_CityGraphics.DrawImage(cityImage, panel_City.DisplayRectangle);
}
