Maya Python scale picture

Question

How to scale a picture to fit a window/layout?

With the code below the original image is not actually enlarged to 300px, it is displayed with the original image size instead.

import maya.cmds as cmds

if (cmds.window(window1, exists=True)):
    cmds.deleteUI(window1)

window1 = cmds.window(w=300, h=300)
layout = cmds.columnLayout(w=300, h=300)
cmds.picture( image='image.png', w=300, h=300)

cmds.showWindow( window1 )

Answer 1

Try this

import maya.OpenMaya as om

def resize_image(source_image, output_image, width, height):

    image = om.MImage()
    image.readFromFile(source_image)

    image.resize( width, height )
    image.writeToFile(output_image, 'png')


resizeImage('<source_image.png>','<output_image.png>', 300, 300)
