Removing separation in tilesets?

[SuperSledgeBro]

I made this code in Game Maker Studio, it draws the tileset you want without the separation:

tileamount_w = 10
tileamount_h = 10
tilesize_w = 16
tilesize_h = 16
sep = 1
background_id = bg_tileset

for (i = 0; i < tileamount_w; i += 1)
{
for (j = 0; j < tileamount_h; j += 1)
draw_background_part_ext(background_id, (tilesize_w + sep) * i, (tilesize_h + sep) * j, tilesize_w, tilesize_h, (tilesize_w * i), (tilesize_h * j), 1, 1, c_white, 1)
}

Specify the amount of tiles to draw with "tileamount_w" and "tileamount_h" and the number of pixels in the separation in "sep". It doesn't save to an individual PNG file, but you can take the easy route and just... Press the print screen button.
