ImageRender: size

size
  • Returns the source image size.

Return Type: 

  • integer list [ width, height ]

width:
  • pixel width of the source image
  • Type:  integer
height:
  • pixel height of the source image.
  • Type:  integer
Note:
  • Video Texture width and height should be a power of 2.
  • If the Video Texture is not a power of 2, the graphics pipeline automatically rescales the texture to a power of 2.
Power of 2:
  • 2 x 2
  • 4 x 4
  • 8 x 8
  • 16 x 16
  • 32 x 32
  • 64 x 64
  • 128 x 128
  • 256 x 256
  • 512 x 512
  • etc
  • And any combination.  128 x 512 is a power of 2.
Example:
  • A texture of 300 x 300 will be automatically rescaled by the graphics pipeline to 512 x 512.
  • A texture of 130 x 520 will be automatically rescaled by the graphics pipeline to 256 x 1024.
Sample Code

###################### get the source image size

# import bge module
import bge

# get current scene
scene = bge.logic.getCurrentScene()

# get a list of the cameras
camList = scene.cameras

# get camera being used for render to texture
# my camera is named Security_Cam
cam = camList["Security_Cam"]

# get list of objects in scene
objList = scene.objects

# get object to render to
# my object is named SecurityMonitor
obj = objList["SecurityMonitor"]

# get the SecurityMonitor material ID
# Name of my render material is Screen
matID = bge.texture.materialID(obj, "MAScreen")

# set the texture
renderToTexture = bge.texture.Texture(obj, matID)

# get the texture image
renderToTexture.source = bge.texture.ImageRender(scene,cam)

# get image size
image_size = renderToTexture.source.size

# save RenderToTexture as an object variable
obj["Render"] = renderToTexture

# update the texture
renderToTexture.refresh(True)
