[magick-users] ImageMagick regression? Or new feature?

[Fred Weinhaus]

I don't really follow this, but it appears that you have the order of 
images wrong and am missing a -composite or -flatten with the first 
-compose multiply.

The convert syntax is

convert background overlay -compose method -composite

Below you create a white image, but don't follow with the overlay 
image until after the -compose multiply and then there is no 
-composite (or you have an out of place -compose multiply after the 
xc:white and then again after the in.jpg with a -compose multiply 
-flatten.  When you have missed a composite command, you end up with 
multiple outputs rather than the two image being composited into one 
image.

see http://www.imagemagick.org/Usage/compose/#compose


Perhaps I am missing something here, but your command does not make 
sense to me. Perhaps it worked before because IM was more forgiving 
of errors and ignored the misplaced -compose multiply.

Perhaps you can explain functionally what you are trying to do and 
what each step corresponds to.

Also you say things are twice as big, but your image is 750x750 but 
you are usinig a 1159x1515 size white image. So the result will 
likely be that big.








>convert.exe -density 150 -size 1159x1515 xc:white -compose multiply (
>in.jpg -repage 1159x1515+0+0 ) -compose multiply -flatten ( in.jpg
>-repage 1159x1515+409+765 ) -compose multiply -flatten -compress zip out.tif
