本文介绍了一款用于3ds Max的MaxScript插件，该插件实现了图像的反色效果。通过修正原代码中的拼写错误，提高了代码的可用性和效率。修正后的代码展示了如何逐像素地反转RGB颜色值。

原代码这里有很多的错误，因为MaxScript没有关键字提示功能，所以主要是拼写上的错误：

plugin rendereffect negEffect name:"反色" classId:#(0x79cc21e5, 0x74c96866) ( rollout negRoll "NegRoll" ( label l1 "反色 By 风达" ) on apply r_img progressCB: do ( progressCB.setTitle "negEffect" for y =0 to r_img.height-1 do ( if progressCB.progress y (r_img.height-1) then exit img_line = getpixels r_img [0,y] r_img.width for x = 1 to r_img.width do ( clR = 255 - img_line(x).r clG = 255 - img_line(x).g clB = 255 - img_line(x).b imgline[x] = color clR clG clB imgline[x].alpha ) setPixels rImg [0,y] img_line ) ) )

修改过后的代码：

plugin rendereffect negEffect name:"反色" classId:#(0x79cc21e5, 0x74c96866) ( rollout negRoll "NegRoll" ( label l1 "反色 By 风达" ) on apply r_img progressCB: do ( progressCB.setTitle "negEffect" for y =0 to r_img.height-1 do ( if progressCB.progress y (r_img.height-1) then exit img_line = getpixels r_img [0,y] r_img.width for x = 1 to r_img.width do ( clR = 255 - img_line[x].r clG = 255 - img_line[x].g clB = 255 - img_line[x].b img_line[x] = color clR clG clB img_line[x].alpha ) setPixels r_Img [0,y] img_line ) ) )
