bmp from scratch
I'm interested in the algorithm that would create a bmp, or gif file
from a matrix of numbers say 400x400. Also in code that would take arbitrary scaled data and translate those numbers into gray-scale or color representations. Anyone know about this? Jim |

Never done it, but it shouldn't be a problem.
Maybe start with this one: http://gpwiki.org/index.php/VB:Bitma...at_Information RBS "Jim" wrote in message ...

Also in code that would take arbitrary scaled data and translate those numbers into gray-scale or color representations. Anyone know about this? Shameless plug. I do an Imager addin for XL that does exactly this for greyscale and various commonly used false colour mapping with optional linear and log scaling. It is useful for modest amounts of bulk data. http://www.nezumi.demon.co.uk/consult/excel/image.htm Hope this helps. Regards, Martin Brown |
