MaxScript生成Gif

需要用到一个NGif的库，是国人编写的，不过到我写这个帖子的时候还不是以dll文件的方式提供，是给出的代码。这里我编译了一个dll.

这个dll文件需要和脚本在同目录执行，脚本需要保存下，或者读者自己修改一下DotNet.LoadAssembly

简单的生成Gif的MaxScript如下

localPath = GetFilenamePath (GetSourceFileName())
DotNet.LoadAssembly (localPath + "Ngif.dll")
GifEncoder = DotNetObject  "NGif.AnimatedGifEncoder"
DotNetImage = DotNetClass "System.Drawing.Image"
theGifFileName = "d:\\test.gif"
gifFrames = #("d:\\01.png","d:\\02.png","d:\\03.png")
GifEncoder.Start(theGifFileName )
GifEncoder.SetDelay(500);
GifEncoder.SetRepeat(0);
for tempframe in  gifFrames  do
(
    tempImage = DotNetImage.FromFile tempframe 
    GifEncoder.AddFrame tempImage
    tempImage.Dispose()
)
GifEncoder.Finish()

　　

localPath = GetFilenamePath (GetSourceFileName())
DotNet.LoadAssembly (localPath + "Ngif.dll")
GifEncoder = DotNetObject  "NGif.AnimatedGifEncoder"
DotNetImage = DotNetClass "System.Drawing.Image"
theGifFileName = "d:\\test.gif"
GifEncoder.Start(theGifFileName )
GifEncoder.SetDelay(40);
GifEncoder.SetRepeat(0);

timeStart = AnimationRange.Start.Frame
timeEnd = AnimationRange.End.Frame

for i = timeStart to timeEnd do
(
    SliderTime = i
    tempframe = "d:\\test.png"
    render outputfile:tempframe vfb:false
    tempImage = DotNetImage.FromFile tempframe 
    GifEncoder.AddFrame tempImage
    tempImage.Dispose()
)
GifEncoder.Finish()
