Sorry if this is a known problem.
ASS {\clip( drawing )} works ok with Textsub.vdf, but VSFilter doesn't like this. Can anyone reproduce my problem? Tested the official 2.37 VSFilter and celtic_druid's 20060512 VSFilter on Win2K and XP. The problem seems to be alpha-related, i.e. the color is not as opaque as it is supposed to be. Also the border is jaggy-ish. I'm always feeling Textsub.vdf is better than VSFilter, but I thought the bugs in VSFilter were already fixed...
Does anyone know any workarounds...? Thank you very much in advance!!

Ok, I found a workaround. The result may not be perfectly the same, but usable enough. The tricky part is, to draw the same face 4 times overlapping along the z direction, to make it opaque enough. (If the face was not opaque, this hack would be slightly more complicated, but it should be possible to adjust the alpha of each layer so that the final alpha will be what you want.)
Code:
[list=a]
Style: TestStyleFace,Verdana,80,&H0000ffff,0,-1,-1,-1,0,0,0,100,100,0,0.00,1,1,0,7,0,0,0,0
Style: TestStyleBord,Verdana,80,-1,0,&H00000000,-1,-1,0,0,0,100,100,0,0.00,1,1,0,7,0,0,0,0
; Draw the same face without border 4 times on different layers (in theory quite meaningless but this is the hack)
