I mean the current CVS gimp has so much nice stuff for graphics tablets and such, that it'd suck to leave the Hollywood branch without them?

This would require substantial changes to the GIMP core to support. It might be possible to load such an image, but it would have to be converted to standard 8-bit RGB (with concomitant information loss) to be manipulated. Kelly
RE: high dynamic range images
Sorry about that. High dynamic range image can be thought of as having 3 floating point values for RGB instead of 8 or 16 bits per channel (usually expressed in 4 unsigned chars as RGB and an exponent). It is pretty hot in computer graphics since raytracing algorithms can output not just color but actual "brightness" values of the scene. -Mok > -Original Message- > From: Kelly Lynn Martin [mailto:[EMAIL PROTECTED]] > Sent: Thursday, October 21, 1999 5:04 PM > To: Byong Mok Oh > Cc: [EMAIL PROTECTED] > Subject: Re: high dynamic range images > > > On Thu, 21 Oct 1999 15:28:48 -0400, "Byong Mok Oh" > <[EMAIL PROTECTED]> said: > > >Hi, Has anyone written a plug-in that reads in a high dynamic range > >images? > > You'll have to define what you mean by "high dynamic range image". > > Kelly >

high dynamic range images
Hi, Has anyone written a plug-in that reads in a high dynamic range images? thanks, Mok --- b y O n g m O k O h MIT Computer Graphics Group http://graphics.lcs.mit.edu/~boh/ http://www.bam.com/send.htm & (617) 872-6684
