Get image size?

[Anonymous]

hi

I have a project in python for my school.
My question is : How to get a image size in maya
For exemple I create a lambert material, I put a externe
file (texture). And I want to get the size of my texture
for create a plan with a good ratio.

The .outSizeX and .outSizeY attrs on the file node will get you what you want.

This is my script to do just what you're asking about

import maya.cmds as m
import os.path
def createPlaneForTexture(path,name=False):
  if not (os.path.exists(path)):
    print "Error: file not found: "+ path + ", exiting"
    raise IOError
    return
  fileNode = m.createNode("file")
  m.setAttr (fileNode+".fileTextureName", path, type="string")
  wPixels = m.getAttr(fileNode+".osx") / 10.0
  hPixels = m.getAttr(fileNode+".osy") / 10.0
  if name:
    polyNode = m.polyPlane(w=wPixels, h=hPixels, sx=1, sy=1,name=name)
  else:
    polyNode = m.polyPlane(w=wPixels, h=hPixels, sx=1, sy=1)
  
  lambertNode = m.shadingNode("lambert", asShader=1)
  m.connectAttr(fileNode+".outColor", lambertNode+".color")
  sgNode = m.sets(renderable=1, noSurfaceShader=1, empty=1, name=lambertNode+"SG")
  m.connectAttr(lambertNode+".color", sgNode+".surfaceShader",f=1)
  m.sets(polyNode, e=1, fe=sgNode)
