wxImage to Texture

[Penguin]

Hi,

I'm using wxPython to get a screenshot from a hidden window how it is described here (http://markmail.org/message/iw3zyw3pfhmqxos7).

Now I want to use the screenshot image as a texture on a Vizard object (e.g. a plane) without writing it to the harddisk and read it again with viz.addTexture() because this would be slow for repetitive image generation with short time intervals.

Is there a way to load the wxImage direct to a texture? Maybe using viz.addTextureFromBuffer() in some kind?

Yes, you can copy the image data directly into an existing Vizard texture using the texture.setImageData() command. Here is a sample script:import viz
import wx
viz.go()

def WXIMAGE_TO_TEXTURE(image,texture):
"""Convert wxImage object to Vizard texture"""
img = image.Mirror(False)
tex.setImageData(img.GetData(),[img.GetWidth(),img.GetHeight()])

#Create wxImage from a bitmap
app = wx.PySimpleApp()
img = wx.Image('image.bmp')

#Create blank Vizard texture
tex = viz.addBlankTexture([1,1])

#Copy image to texture
WXIMAGE_TO_TEXTURE(img,tex)

#Create quad to display texture
quad = viz.addTexQuad(pos=(0,1.8,2),texture=tex)
