After you finish an image, you want to post it to some site on the web, right?? How do you treat your fractint images? I´m using paintshop pro 5.01, and ultra-fractal. I save the parameters, open them in Ultra-f and render them to disk, the size I want to use in my site (640x480). I use the png format I don´t know exactly why. I open it in PSP, and save as jpg. Now, can I open the gif image in PSP and do the antialiasing there? I haven´t found out how with psp´s documentation, I guess they use another name for it. What settings do you use when compressing with jpg?? I understand that depends on the image, but is there a general rule? What is an acceptable size for the pictures? I have a thumbnail page, you click on the thumbnail, you get a page with the bigger iamge. I´m talking all the time about this picture. I imagine that if the visitor has clicked on the thumbnail, he/she/it also is willing to wait a little longer for the image to appear, so I don´t tend to make the picture too small. I usually got pictures about 50-70k big. Is that ok? May I let them be even bigger and therefore better? So, that´s a lot of questions for today, and I hope you can help me out.

Jones" Subject: Re: (fractint) anti aliasing Fernando, - Now, can I open the gif image in PSP and do the antialiasing - there? Yes. Render larger than you need--at least 2x, so if you need a 640x480 image, render at 1280x960 or larger. Open the image in PSP. Convert it to a 24-bit image. Resize to 640x480. If the result is too soft, apply a slight (slight!) sharpen effect. Save as a JPEG. All the FractInt images in my galleries were done with this technique (although not with PSP). - What settings do you use when compressing with jpg?? You'll have to experiment to see which ones work best. Generally, use as much compression as you can that doesn't mangle the image. Once you find the "sweet spot" you won't have to move too far to one side or the other when saving your pictures; most fractals will use about the same settings. - What is an acceptable size for the pictures? For a 640x480 image, somewhere between 50K and 150K seems reasonable. A few very "busy" images will need to be larger than that to prevent JPEG from mushing them up. Damien M.

I don't know about life being a bowl of cherries, but today's fractal midget certainly is in a bowl of cherries. At least 16 cherries surround the midget, and the smaller eight cherries still have their cherry-stems attached. It's no surprise that I named the picture "Midget With Cherries". The formula behind the cherry bowl is 1.15*(-(Z)-(1/Z))+1/C, another unlikely candidate for a respectable fractal. One would never think that combining Z and 1/Z could create a worthwhile fractal, but sometimes in the world of fractals the simplest formulas create the most complex images. This midget is surprisingly healthy. I tried to kill it by raising the bailout value, so I could examine its ghost with various inside fills, but it refused to die, even with the bailout set to an apocalyptic 10^250. It does change its colors however at such an extreme bailout value. It also takes about seven times as long to render, and the logmap must be reset from 283 to 2308. I have attached both the bailout=200 and the bailout=10^250 parameter files, though only the image with the bailout of 200 has been posted to the usual sites. At 15 minutes and 104 minutes, the parameter files try one's patience. To avoid impatience, I recommend downloading the image with the bailout of 200 from: or from: If you wish to see the image with the bailout of 10^250, you'll need to run the second parameter file, and be extra patient. The difference is striking. The fractal weather, (Is there any other kind?), was boringly average today here at Fractal central, with partly cloudy skies and a temperature of 48F (9C) that was just warm enough to enable the fractal cats to enjoy an hour or so outdoors in the yard. I hate to disappoint the fractosophy fans, but the fractal philosophy never got off the ground today. There was simply too much paying work and too many problems for my philosophical mood to reach full stride. But I've got much to say, and I'll be saying it in my typical outspoken manner in the not-too-distant future. For now, it's time to close the fractal shoppe, feed the cats and call it a night. Until next time, take care, and remember that patience is rewarded.

The image is all red and green color. There is nothing new in the underlying forms, which have appeared in several previous FOTD's. The formula behind the image subtracts Z^(-3) from 1/10 part of Z^3 before adding C. I could rate this effort only a 4, because I put very little work into it. Most of my spare time today was spent searching for and formatting the little philosophical story I wrote a few years back, which will be posted to the philofractal list in a couple hours. After a moment's thought, I named today's FOTD "Old Red-eye". The midget at the center does give somewhat of an impression of a staring eye, and the surroundings certainly are red enough to warrant the title. The parameter file is fast enough to make running it a bit less work than going for the download. But for those who would rather download the JPEG file of the image, it can be found posted to: and also to: The fractal weather today was a non-event. Warm sun and a temperature of 56F (13C) kept the fractal cats happy. Though the philosophy is cooking nicely, it is not quite ready. But the little story I will post shortly to the philofractal list will more than make up for the delay. Now I see it's time to shut down the fractal shoppe and call it a night. Until tomorrow, take care, and whatever happened to the Murphy who wrote Murphy's law?

I use PSP4 and there are 2 options to change the size of the image. If you resize, you suppress only unused pixels and the result is very bad. To antialias you must choose Resample (I think it is the word used in the English version, because I use the French one). Indeed this option can only be selected if the image uses 24 bits for colors (if not -i.e. GIF images- go to the bottom of the menu Colors).

There is so seldom any reason to "resize" without resampling that to present such an option when a better one is available is, I think, very confusing to the user. Other graphics apps don't generally do this. So, your point is well taken: in PSP, this option is called "Resample", not "Resize". Damien M.

I can't say that after viewing the slices I'm any closer to visualizing the entire 4-D monstrosity, but the slices are fascinating indeed. For any who might be interested, the URL of the page is: http://www.graphics.cornell.edu/~gordon/peek/600slice/index.html I was told of the page by Andrew Coppin. Today's FOTD is one of the most unusual scenes I have yet found by using nothing more than the everyday equal-iteration bands. It is a scene in the fractal that results when Z^0.78 is subtracted from Z^0.5 before adding C. I named the picture "Fire Midget" in recognition of its liveliness rather than as an attempt to describe the scene. It is an unusually easy fractal to color, working wonders with almost any color scheme. I could easily have chosen any of a dozen alternate color palettes and still had a respectable image. While searching through the parent fractal for today's image, I found several more interesting scenes. I may post some of these as FOTD's in the near future. The 4-1/2 minutes it takes to run the parameter file is just long enough to make a download of the image file the better choice. That image may be found in JPEG format ready for downloading on Usenet at: and on the Web at: The fractal weather today once again turned out boringly average. The temperature was 56F (13C), but the lack of sunshine kept the cats indoors. The latest eruption of fractal philosophy has not yet matured, but I've still got it cooking. Keep posted for the big event in the near future, maybe even tomorrow. Until then, take care and when the world gets you down, restore hope with a fractal.

It earns that superior rating because of its extraordinarily realistic representation of an actual 3-D scene in the world of fractals, wherever that may be. The formula is a slight variation on the formula of yesterday's image. This time Z^0.65 is subtracted from Z^0.55 and the difference multiplied by a factor of 9. Though most of the image was a matter of luck, I did spend a bit more time than usual fine-tuning the color palette. I named the picture "Jungle of Fractals". The name is well-earned, considering the jungle of lush tropical growth surrounding the central midget, which glows with a bronze aura. At a running time of over 17 minutes on a modest Pentium 200mhz, the parameter file demands a bit of patience. For the impatient, the JPEG'd image file has been posted to the binary Usenet newsgroup: and to Paul Lee's web page at the URL: The fractal weather today was spring like -- warm enough in fact for the fractal cats to spend several hours sitting in the sun on the porch, which faces SSW. The temperature of 68F (20C) kept them stretched out most of the afternoon. Unfortunately, the sun finally went down, and the cats came indoors, where they assumed their customary positions for the rest of the day. For today, that's it, but we'll have more tomorrow. Until then, take care, and when fractals call, heed the call.

(Now that's a novelty in itself.) The topic of my musings was the fourth dimension, (No, I'm not an egg-head.) and in particular the hypersolid figures of 4-D space known as polytopes, whose boundaries are 3-D solids. In 3-D space there are semi-regular polyhedrons whose faces consist of two or more different regular 2-D polygons. The truncated icosahedron or soccer-ball figure, a semi-regular polyhedron which consists of 20 hexagons and 12 pentagons, is one of these. This afternoon, I wondered how many semi-regular 4-D polytopes are possible, whose cells consist of two or more varieties of the five regular polyhedrons. It is immediately apparent that cubes and dodecahedrons cannot function as cells of a semi-regular 4-D polytope, since these are the only regular 3-D polyhedrons with squares and pentagons as faces, and as part of a 4-D polytope, in which the cells are joined at their faces, there would be nothing to join them with. This leaves us with four possible combinations of the three polyhedrons with equilateral triangles as faces: tetrahedron- octahedron, tetrahedron-icosahedron, octahedron-icosahedron, and tetrahedron-octahedron-icosahedron. Semi-regular 4-D polytopes might be possible with any of these four combinations of polyhedrons comprising its cells. I was just starting to figure the number of possible configurations of these four combinations, when the phone rang and my reverie ended. But although I never did solve the problem I had invented, I did later find a fractal. Today's fractal is another in my series of plant-like images. It reminds me of a scene in an imaginary fractal forest, with lush, exotic alien plants springing into the air, while in the background the Minibrots dive for cover. Since the parameter file takes a somewhat unreasonable 13 minutes to render, it would be more reasonable to download the JPEG'd image file from: or from: The fractal weather today was a foretaste of Spring, complete with a temperature of 79F (26C) and the obligatory late- afternoon thunder-shower. The fractal cats took full advantage of the warmth, spending nearly all afternoon lying on the porch, absorbing the sun. The fractosophy, however, made little progress today. I'll work at it again tomorrow. Until then, take care and be good, but not so good that it stops being fun.
