[svg-developers] Expanded SVG: what sort of images could be created with
Happy New Year! You may try my small gift- PhotoToPicture converter. This one converts raster into vector, by for the reasons, explained before, its output is a raster too. As for me, looks rather pretty. Think about it as a filter, what simplifies an image and make it looks as an art. One useful option is included- output can be enlarged up to 893% of its original size (this is result of a mistake in my calculations- I wanted up to 800%, but leaved it as it is). Download is available at http://www.smartfills.com/Html/PhotoToPicture.zip . Output is just same thing as expanded SVG could be. It is clear, what sort of additional records should be added to SVG specification to reproduce such sot of images.

It was presented by some folks from INRIA, Grenoble U, U of Washington and Adobe. They seem to be talking about much the same thing as what you have been talking about and have similar observations about the limitations of more primitive gradients. It starts with a cubic bezier and then allows color gradients on either side, together with a set of blur control points that control the transitions between the two halves. They also have come up with a way of computing all this in a practical way, that looks very promising. A brief demo can be seen at http://www.youtube.com/watch? v=lEVe7vU5WiU . The work certainly reminded me of what you've been working with for some years now, though it may in fact be a quite distinct approach. Regards David [Non-text portions of this message have been removed] Thanks, I new about them. I was trying to make contact with all of authors, listed in quoted article. One answerd me once: Hi Andrew, indeed, your work seems to be very similar to ours! Especially your vectorization results are very neat, and your color interpolation seems to be faster than our diffusion process. From our experience, users of gradient meshes are looking forward to play with more intuitive tools for the creation of smooth vector gradients. Thanks for showing us your results, let us know about your next projects, Regards Adrien (Bousseau) It was the first and the last my contact with this group. No matter what efficient solutions I offer, the real use will be only if at last one vector file format will be expanded. Well, I'll inform this group when the next version of my converter is complete to testing. Currently I have some problems with preserving original colors during resizing. regards, A - To unsubscribe send a message to: svg-developers-unsubscr...@yahoogroups.com -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

If the distance from P0 to P1 is less than distance from P0 to P5, you recommendation is to select point P1, P2, P3. Well but why do you think, that distance from P0 to P4 cannot be less than from P0 to P1?! Well, but what makes you think that if a curve is continuos, minimal distance cannot be from P0 to P4?! Let's speak about one single link of a Bezier curve. To get points with minimal distance from some point P0 to this link of a Bezier curve, one has to find roots of 5- order polynom (is this a proper term?) Square of a distance from P0 to P, belongigng to Bezier curve's link, is a polynom. Its first derivate is a polynom too. One has to find its roots, to calculate distance from P0 to corresponding points and compare with end points of aforesaid link (yep, roots must be between 0 and 1). There is no other way to calc minimal distance correctly. Coruse, having more than one link (polyBezier) some links could be excluded due to the fact that each link lies inside convex polygon, based on control points of a Bezier's link. - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

I am glad that you found the solution. This also saved me from the calculation. If a curve is defined by a bunch of points, I propose a simple algorithm that should work for most of the cases (excluding some cases with inflection points): (1) Calculate the 3 distances - 2 to the end points of the curve and one to a middle point. (2) Continue with the curve limited by the end point with shortest distance and the middle point. Now you are left with a curve of about half of the length of the previous. (3). Calculate the distance of the middle point of the new curve. (4). You have now again two end points and and one middle. From here on repeat (2) and (3) till you get the required minimal distance. This algorithm lets you calculate number of distances much lower than the number of the total points of the curve. For instance if you have 1000 points in total, you'll finish with calculating about 10 distances. Good luck, Samy Are you kidding? Let's try to imagine 5 points- P1, P2, P3, P4 and P5.

Actually, this sort of graphic could be implemented into SVG without much problems. Gradient fills without meshes requires only set of vertices for each region to be painted, so it is simpler than cover region with convex polygon, create triangular meshes (or distorted rectangular, as it is realized in Illustrator). - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

[svg-developers] Visual effects, produced by advanced gradient fills
This is an easy sample of which sort of visual effects can be produced by the advanced gradient fills. Prog is available at http://www.smartfills.com/Html/GradientFillsDemo.zip . Unzip and run. Four buttons with digits change regime a little- they set number of colors of an output image. Output rectangle is painted by interpolation of random set of vertices, what are randomly moving on this rectangle. Nothing more. Course, there could be more things like set of non-rectangular regions, but this is probably task for an artist more than for a programmer. I wanted only to demonstrate one of possible ways how advanced gradient fills could be used. - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

[svg-developers] Advanced SVG and animation
Who has an interest to see how advanced gradient fills could be used in animation, download a tiny program from http://www.smartfills.com/Html/newexamp.zip . Unzip and run. You only need move cursor and look at what happens. This sort of vectors could be without much problems defined, using SVG constructions (problem course, it to get browsers to understand them). This kind of 2D interpolation requires only set of vertices plus bounding contour and could be done much faster- this demo has no optimization at all. - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

[svg-developers] Advanced gradient fills
People, there are things, what can make SVG graphic more flexible and impressive. I do know (thanks to Mr. Ferraiolo), that there must be serious reasons to expand SVG specification (at least two progs, browsers mostly), but on the other hand implementation of advanced gradient fills promise so much... For example, RaveGrid is proclaimed as an extra quality raster to SVG converter. Well. May be someone wants to see, what is really qualitative conversion. Visit www.smartfills.com and download SVSViewer. I think, such techique could be used in Web with a great benefit too. Small vector files looking like nice raster ones, not like a cheap Japanese cartoon.
