Title: Think BRIGHT is good?
Post by: Sesquipedalian on August 11, 2003, 03:28:21 pm

I am interested in running a comparison of BRIGHT's ability to reduce colour palettes with Corel Photopaint's.  I have heard people rave about BRIGHT, so I want to see whether I should switch or not.  I am somewhat skeptical of BRIGHT's ability to outperform Photopaint, so I'd like someone to take 30 seconds and try to convince me.

Here, then, is the challenge:  Take this 24-bit colour bitmap
http://www.3dap.com/hlp/hosted/scroll/misc/test24bit.bmp
and reduce it to 8-bit (i.e. 256 colour) using BRIGHT.  Then we will compare it with this result from Photopaint:

Yes it is. Use a colour count on Irfanview or something.

Even if Photopaint does outperform BRIGHT in single image color reduction, but can Photopaint make a single palette for a sequence of images without any noticable quality loss?

Argh not if you can figure out how th #$#@ you can do it. Vilcakis would you mind posting your .bat file so I can try that?

put bright.exe in the same folder as your images,
make a bat with this in it
bright namel*.tga -common -o

this will convert all images that have 'name' in there name (like name0000 name0001 name0002 ect)

then run the bat

and lets try a diferent test
(http://freespace.volitionwatch.com/blackwater/test.bmp)

first PSP's color reduction in nearest color mode
(http://freespace.volitionwatch.com/blackwater/testpsp.bmp)
now in dither
(http://freespace.volitionwatch.com/blackwater/testdpspither.bmp)

this is what bright made, unfortunately bright does not suport dithering, so you're color reduceing method may provide better in this example
(http://freespace.volitionwatch.com/blackwater/testbright.bmp)

I still think bright is much better at real texture reduction as it seems to take shapes into acount

Will it change the originals or will it generate new files? And is namel a mistake or is it supposed to be that way?

My advice is to try both. It takes less than a minute to convert a file with Bright so why not try it and see if it did a better job?
