[Closed] .net Image resizing

Feb 26, 2013 3:01 pm

I am looking for an efficient means to resize bitmaps in max using .net, whereby i can make use of the HighQualityBicubic interpolation.

Here is a snippet of VB code from msdn

Dim image As New Bitmap("GrapeBunch.bmp")
        Dim width As Integer = image.Width
        Dim height As Integer = image.Height

        --Shrink the image using high-quality interpolation.
        e.Graphics.InterpolationMode = InterpolationMode.HighQualityBicubic

        --Pass in the destination rectangle, and the upper-left corner, width,  
        --and height of the source rectangle as above.
        e.Graphics.DrawImage( _
            image, _
            New Rectangle(290, 250, CInt(0.6 * width), CInt(0.6 * height)), _
            0, _
            0, _
            width, _
            height, _
            GraphicsUnit.Pixel)

Unfortunately my knowledge of VB is somewhat limited, can any VB scripters suggest a way of implementing something similar directly in maxscript?

Any thoughts or suggestions much appreciated.

something like that:


fn dotnetImageResize image width height =
(
	new = dotNetObject "System.Drawing.Bitmap" width height image.PixelFormat
	g = (dotnetclass "System.Drawing.Graphics").FromImage new
	
	g.SmoothingMode = g.SmoothingMode.HighQuality
	g.CompositingQuality = g.CompositingQuality.HighQuality
	g.InterpolationMode = g.InterpolationMode.HighQualityBicubic
	g.PixelOffsetMode = g.PixelOffsetMode.highQuality
	
	g.DrawImage image 0 0 width height
	new
)
