Hans,

Sounds pretty impressive.  As a point of reference, do you have timing 
data for the existing MKII and MKIV image processing code?

Cheers,
Mike

Hi,

as some of you may know, there is an mplib project ..

last week taco and spent quite some time on exploring the integration in 
luatex (and therefore mkiv)

experiments with loadiing the format, processing graphics and conversion 
to pdf show a throughput of less than 0.001 seconds per graphic; a usual 
we did much timing and although experimental, the code is already pretty 
okay, just to give an idea:

	mkiv lua stats : metapost processing time  - 6.834 seconds (loading: 
0.014 seconds, execution: 1.474 seconds, n: 15000)

indeed, that's 15K graphics in 7 seconds.

so, the next couple of months i'll start providing an adapted mp 
handling mechanisms. among the possible options are

- extensions based on pre/postscripts (instead of specials)
- multiple mp engines (\startuseMPgraphic[metafun]{name} and such)

so, if you have specific wishes ... now is the time to let them know


Hans
