is it possible to change an image?

[Ankou]

Hi,
Is it possible to draw on an image and if not, why does Image has a save function?

Is it possible to draw on an image

Not yet, but it'll be implemented soon (see "render to image" feature).

why does Image has a save function?

For that :

Code: [Select]

window.Capture().SaveToFile("screenshot.jpg");
That (next version) :

Code: [Select]

image.Copy(source, x, y);
...
image.SaveToFile("tileset.png");
Or that :

Code: [Select]

image.SetPixel(x, y, color);
...
image.SaveToFile("my_drawing.png");
