dotnet drawing api : 1 Bit Image Conversion

Hello,

I am comverting a TIF to 1 bit and this works really well for all that I
need it for, except for the amount of time it takes to accomplish this. On
a 3 page Tif it is taking over 5 seconds on my computer and over 8 on
others. I know this is small fries, but I really need to speed up this
process.

I have tried making the thread for the application the highest priority - No
difference - possibly slower.

Would converting the file to a bigger resolution speed this conversion up.
If so how would I accomplished this?

Any ideas will be greatly appreciated,

Chuck

Hello,

I was unable to resolve the speed problem, but I have figured that the
program I am trying to associate my program with will read 16 bit Tifs.
Anyway, I don't need to convert it to 1 bit for it to work which has caused
the application to perform a lot faster.

Thanks for all your help,

Chuck

Hello Charles,
seems you have already solved. Anyway, I have read somewhere
that 1 bbp conversion can be done which much higher speed (a few
millisecs)
using GDI instead of GDI+. In case you would need it,
you should probaly search in that direction. I am sure in the GDI
group they have posted it several times...
