Show Picture for window background?

[Ulqiorra]

Hey, I was just wondering, for my new HUD script...

    How would I show a picture for the background of a window.
    I tried

self.contents.bitmap =

and

self.bitmap =

    And I get the error:
    NoMethodError occured.
    undefined method "bitmap="

So how do I do this?

It would be self.windowskin, I think. And it'd have to be a bitmap object, i.e.:

self.windowskin = Cache.picture("MyWindowBackground.png")

Ah, thank you. One more question,

How would I alter the width of a bitmap?
Ex:

bitmap.width = var

That's what I've tried, but I get a
NoMethodError for "width=".

You can't alter the width of a bitmap. You can however choose which rect of the bitmap you transfer. Like so:

bitmap = Bitmap.new(width, height)
other_bitmap = Cache.picture("MyWindowBackground.png")
bitmap.blt(x, y, other_bitmap, Bitmap.new(bx, by, bw, bh))

Ok. So bitmap is your objects actual bitmap. Just choose your width and height here.
other_bitmap is the bitmap you will be transferring from.
x, y are the position on the bitmap you will be transferring.
bx, by, bw, bh is the rect from the other_bitmap you will be transferring from.

I can better explain it with this:

Thank you, I figured I might be able to do something
like that, but I wanted to be sure. Also, the
"self.windowskin =" didn't work, any other ideas?

EDIT: it is giving me an error, wrong number of arguments(4 for 2) in the "blt" method.

"didn't work", what do you mean by that?
Did it give you an error, or didn't it do what you wanted?

The 'blt' method has either 4 or 5 arguments. Unless you have less than 4 arguments, it should not return an error.

Also note, that if you're planning on having a single picture wrap the entire window, it shouldn't work with windowskin, as windowskin takes out the small portion to the left in the skin as the window's bitmap. Or at least that's how I understood it anyway.

 

[Ulqiorra]

Ok yeah, FireRaven, that's what's happening. Do
you know how to use the entire picture as the
background?
Also, the erroring code on my 'blt' method is:

    bitmap = Bitmap.new(width,16)
    vis_bitmap = RPG::Cache.picture(filename)
    if var > width
      bw = width
    else
      bw = var
    end
    bitmap.blt(x, y, vis_bitmap, Bitmap.new(x, y, bw, 16))

**var, width, x, y, and filename are for arguments in the method.

self.windowskin = Cache.picture("MyWindowBackground.png")

The windowskin option should work. You just need to paste your image into the window portion of the windowskin (left side). And the command should be:

self.windowskin = RPG::Cache.windowskin("MyWindowSkin.png")

Using the windowskin, the bitmap will stretch to fit the window.


Also, in your first try, you were close.

self.contents  is a bitmap object, so you should have tried...

self.contents = Bitmap.new("Graphics\\Pictures\\MyWindowBackground.png")  

Except, In this case you will have a 16 pixel border around your image, and it won't resize / stretch to fit the window.

Be Well

      bw = var
    end
    bitmap.blt(x, y, vis_bitmap, Bitmap.new(x, y, bw, 16))

**var, width, x, y, and filename are for arguments in the method.

The last parameter is Bitmap.new. Bitmap supports only two arguments. You need to change Bitmap into Rect. So the command goes:

bitmap.blt(x, y, vis_bitmap, Rect.new(x, y, bw, 16))

I got the bitmap width thing working. I still need the picture background.

Near, Can you post the picture you want to use?

FireRaven, nice catch. (Bitmap -> Rect). I looked right past it.
