Hello,
a part of the function IERGB2CMYK looks so.
function IERGB2CMYK(const rgb: TRGB,: TCMYK;
var......
begin
.....
result.y:=255 - cmyk16.y shr 8;
result.k:=255 - cmyk16.k shr 8;
end
else
with rgb, result do
begin
k := imax(r, imax(g, b));
if k = 0 then
k :=1;
C := r * 255 div k;
M := g * 255 div k;
Y := b * 255 div k;
end;
end;
Then IERGB2CMYK(0,0,0) --> CMYK(0,0,0,1)
that is certain wrong i think.
I believe better, this function is, can maybe your that alters.
function IERGB2CMYK(const rgb: TRGB,: TCMYK;
var..........
begin
..................
result.y:=255 - cmyk16.y shr 8;
result.k:=255 - cmyk16.k shr 8;
end
else
with rgb, result do,
begin
k := imax(r, imax(g, b));
if k = 0 then
begin
C:=255;
M:=255;
Y:=255;
end
else
begin
C := r * 255 div k;
M := g * 255 div k;
Y := b * 255 div k;
end;
end;
end;
many greetings
Klaus

Hello,
you're right and it will be fixed in next minor release.
Anyway I suggest to leave iegUseCMYKProfile=true, to have more accurate conversion.
Many thanks for your fix! |
