dekafka fixed

[jsada]

I saw another post on this, but this should more generic.
Original dekafka doesn't seems to be working in 2.56
It used to go beyond your Framesize.

Here is my usage (added -2),



function dekafka2(clip clip, clip maskclip, int Xstart, int Ystart, int X, int Y, int Amount)
{
ytop = Ystart
ybot = Ystart + Y
xleft = Xstart
xright = Xstart + X
clip = clip.ConvertToRGB32
maskclip = maskclip.ConvertToRGB32
topline = clip.Crop(Xstart-2, ytop-2, X, 2)
bottomline = clip.Crop(Xstart-2, ybot-2, X, 2)
leftline = clip.Crop(xleft-2, ytop-2, 2, Y)
rightline = clip.Crop(xright-2, ytop-2, 2, Y)
logosrc_hor = StackVertical(topline, bottomline).Blur(1.58, 0).BilinearResize(X, Y)
logosrc_ver = StackHorizontal(leftline, rightline).Blur(1.58, 0).BilinearResize(X, Y)
Amount2 = (Y>=2*X) ? 255 : 128*Y/X
# Amount2 is small if X >> Y => logoscr_hor is dominant
logosrc = Layer(logosrc_hor, logosrc_ver, "add", Amount2)
masklogo = maskclip.BilinearResize(X, Y)
logo = logosrc.Mask(masklogo)
clip = clip.Layer(logo, "add", Amount, Xstart, Ystart)
return clip
}

function remlogo(clip tclip, string filename, int x, int y)
{
maskclip = ImageReader(filename, 0, 0)
maskclip = Loop(maskclip, Framecount(tclip))
dekafka2(tclip, maskclip, x, y, maskclip.width, maskclip.height, 256)
converttoyuy2() # In case your output is YUY2
}

# Widescreen
clip1 = Trim(258,6292)

clip2 = Trim(6293,23548)

# Nip & Tuck logo
clip3 = Trim(27748,27909).remlogo("d:\avs\Pics\NipTuck-w.bmp", 331, 308)

# Starship logo (400,346 320x134)
clip4 = Trim(27910,28802).remlogo("d:\avs\Pics\Starship-w.bmp", 400, 346)
