I don't see it that way. PNG only lags JPG compression by about 3 times at moderate to good quality. SVG lags JPG by about 1.5 times if the image has good color segmentation. When closely matching shapes are group together (aka shape grouping), SVG can use the <def> tag to exceed JPG compression. JPG would then lag SVG by about 2 times (but I haven't fully tested it). When entropic shaping (e.g. making a shape that is nearly a circle a circle) reduces noise even further, JPG lags SVG by 10 times. After entropic shaping, almost all of the signal is extracted from the noise (aka very little noise left), then the data is in position for raster to vector conversion. Yes, SVG is vector, but the last step provides for something more than a set of lines that are stuck together. In other words, SVG has continuous mathematical functions. In our tests, it seems that JPG lags this type of SVG by 100 times.
I do agree that its not about trying to replace other technologies, but some technologies are not positioned to have a future. The whole raw signal can be stored in PNG, so I see PNG as a permanent technology. I do not see what role either JPG or PDF will play when SVG is advanced to noise-free continuous mathematical function. SVG has a permanent future on the Internet, but more than that, the ability to provide high quality data to electronic circuits will improve the performance of any electronic circuit that currently relies on frequency based signal conditioning which is nearly all circuits. A circuit that relies on noise free continuous mathematics for its data, will be about 100 times more capable than the way we design electronics today (frequency based signal conditioning). This is the inverse of the old computer rule, "Garbage in, garbage out". ------------------------------------ ----- To unsubscribe send a message to: [email protected] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ----Yahoo!
