I've been able to resolve the 'grainy lettering' on the PNG->JPG issue but
when thumbnailed using mogrify and the below command it still fails.
Basically all I did was clone the image, make it entirely white, swap it,
and put it 'underneath' the original image (made a background image).

 

Also I get an error on -clone -1 or +clone when using mogrify so not sure
what I'm doing wrong there.

 

This works and gives nice smoothing lettering/transition:

convert.exe "frame-1.png" ( +clone -alpha opaque -fill white -colorize 100%
) +swap -geometry +0+0 -compose Over -composite -alpha off -thumbnail 90x90
"frame-1.jpg"

 

This doesn't:

 

Mogrify.exe -format jpg ( +clone -alpha opaque -fill white -colorize 100% )
+swap -geometry +0+0 -compose Over -composite -alpha off -thumbnail 90x90
*.png

 

mogrify.exe: unrecognized option `+clone' @
error/mogrify.c/MogrifyImageCommand/

4560.

 

This doesn't' either:

 

Mogrify.exe -format jpg ( -clone -1 -alpha opaque -fill white -colorize 100%
) +swap -geometry +0+0 -compose Over -composite -alpha off -thumbnail 90x90
*.png

 

mogrify.exe: unrecognized option `-clone' @
error/mogrify.c/MogrifyImageCommand/

4560.

 

 

 

Thanks again,

Matt
