I'm not sure if this is intended or not, if it is, I'd like to know a way of preventing this: I've got this image (which is for testing purposes, the actual one has a texture, but I'm not using it right now): Zoomed in, it looks like this in the JFrame:

These small 'arrangements' are what bothers me, because the image itself should be plain green, just as it is when viewing the tile image with a separate viewer
(like that:)


In the end, drawn as a tilemap, it looks like this (I'm changing the rgb values, that's why it's coloured differently on the left):

My Code: (It draws 15 horizontal tiles and 10 vertical tiles, the orange ones are another piece of code which is irrelevant right now)

BufferedImage singleTile;
    try {
        singleTile = ImageIO.read(new File(filename));
    } catch (IOException e) {
    BufferedImage finalImg = new BufferedImage(tilesX*scaledTileSize, tilesY*scaledTileSize, singleTile.getType());
    for(int i = 0; i < tilesX; i++){
        for(int j = 0; j < tilesY; j++){
            finalImg.createGraphics().drawImage(singleTile, i*scaledTileSize, j*scaledTileSize, scaledTileSize, scaledTileSize, null);

Firstly, It looks to me like whatever app you used to create your blank green texture put that pattern there. Try creating a texture using paint.net and see if the problem still persists. Also please show me the code to render the orange texture it could also be helpful. Also, you said that you are changing the RGB colors. Remove that code and it might solve your problem..

  • \$\begingroup\$ @Tyyppi_77 he doesn't provide a quality question so I cant give him a quality answer. I'm just doing the best I can with the info he provides me \$\endgroup\$ – user116458 May 30 '18 at 13:54
