VRayBitmap and image dimensions

V-Ray V-Ray for 3ds Max Issues

With the standard bitmap, you can do the following:

myMap = Bitmaptexture fileName:"C:\test.png"
myWidth = myMap.bitmap.width
myHeight = myMap.bitmap.height

```​

I have not figured out how to do the same with the VRayBitmap.  The property .bitmap in the Bitmaptexture is a special bitmap controller, but in a VRayBitmap, the .bitmap property is just a text string.  Is there a way to query the map pixel dimensions with a VRayBitmap?

Thanks

For VRayBitmap you can use the method below:

myBitmapFile = "C:\test.png"
myMap = VRayBitmap HDRIMapName:myBitmapFile
myWidth = (getBitmapInfo myBitmapFile)[3]
myHeight = (getBitmapInfo myBitmapFile)[4]

But with this method you may have problems getting the dimensions from the tiled .tx texture. Then you can use the second code:

myBitmapFile = "C:\test.tx"
myMap = VRayBitmap HDRIMapName:myBitmapFile
myBitmapInfo = (dotNetClass "System.Drawing.Image").FromFile myBitmapFile
myWidth = myBitmapInfo.Width
myHeight = myBitmapInfo.Height
myBitmapInfo.Dispose()
```​​​
