Hi!

I just converted a 5 MB .psd file in .eps format
and when I checked its size I could not believe it.

It´s 42 MB!!!

So, I´d like to ask an expert here why is that.

Look forward to hear from you and understand it.

Thanks!

I'm no expert but here's how I think it works: the default EPS standard encoding does not support compression--it's designed to be backward compatible with really old RIPs and other PS rips so it assumes this most straight forward mode. And also, because it's in 7 bit ASCII, not 8 bit binary, it requires extra bytes to encode the 8 bit/color channel translation. And each pixel in a 'straight raster' file requires four bytes a piece.

PSD on the other hand IS 8 bit and it does use a special (lossless) compression encoding-- by default.

Does that help?

Kermie, not sure it would go over well to say you are getting quickies from people on the internet.

BUT I know you can get Poked on Facebook (not sure what that really means...

Quick way to get to the end of long threads

Until we get the page function fixed a quick way to get to the new posts in long multipage threads is to use the filter and set the time for Today or Last Week

How you were working by the end of the video is great, I'm talking about the bottom of the palm you got the basic curve down and then added points to account for the variance in the shape. Positioning...
