You are definitely getting a kind of anti-aliasing effect. When resizing an image to a smaller size you decrease the effect of inappropriately bright single pixels and 'jaggies', because single pixels' color values get averaged* with the adjacent pixels' more correct values, 'cleaning the image up.' Note: ----- *averaged -- not exactly averaged, but a function of the neighboring pixel's color values. There are quite a few algorithms/filters for resizing images. It's important to *not* select (or have selected for you by default) the "nearest neighbor" filter. It just picks a nearby *existing* color value and gives no anti-aliasing-type effect at all. The algorithms/filters I like are: - Lanczose (best), - Bi-cubic (next best) if they are available to choose from. I don't know what filter Fractint uses when you read a high resolution image into (say) half the image's resolution video or Disk Video mode. I've not ever done this to see what happens. I use the image manipulation/viewer, Compupic, to make changes like these to my images. I believe that the free program Gimp: http://www.gimp.org/ that Paul mentioned has a rich feature set, too. > is there a "hot" color (red,orange,yellow etc) version?

FW: Warp Effect Demo
by Hal Lane 15 Jan '15

15 Jan '15

> > With your permission, I'd like to make an animated > > .GIF that... shows your warp and color compression effects. Since this animation is a demonstration of different parameter values controlling the image -- rather than an artistic image -- I took the liberty of annotating each frame of the annotation with the effect that the various parameter sets are creating. I made the GIF animation, but it has a severe problem that I'm unable to fix -- it's dithered. Perhaps there's a bug in the older version of Macromedia Fireworks I'm using, or my understanding of how to control the output of the program is insufficient. I told the program: - to do *no* dithering, - to retain the images' original dimensions, - to not remove unused colors, - to allow 0% loss in GIF compression, - to not crop the frames, - to use an exact color map, and - to not add transparency to the color map. - to do *no* resampling, - and I unchecked the preference: "Faster, but less accurate resampling" but despite this, Fireworks dithered the colors in the images. They look terrible. My best guess is that Fireworks changed the original GIF images to an internal format [perhaps .PNG(?)] and then back to .GIF encoding to write the output file, and dithering the images in the process. I don't recall having this problem before. I'm providing a screen capture of the settings in Fireworks' animated GIF creation wizard: http://tinyurl.com/Animated-GIF-wizard-settings or: http://www.emarketingiseasy.com/Albrecht/MFR_13/150114_Warp_Demo/Fireworks-a nimated-GIF-wizard-settings.jpg It shows that apparently only 89 colors of the original 256 colors in the color map happen to have been selected by the samples [pixels] calculated by Albrecht's program in the five images, so the program decided it could be efficient and choose to use a 128 entry GIF color table in the output animated GIF. It may be that each of the original five Fractint images also were encoded with this size color table/map. [Anyone have any ideas about how to stop Fireworks from dithering the GIF output?] However, I decided to make the animation available anyway, http://tinyurl.com/Warp-Demo-Animation or: http://www.emarketingiseasy.com/Albrecht/MFR_13/150114_Warp_Demo/Warp-Demo-A nimation.gif since it still does show Albrecht's warping and color compression effects clearly -- despite the unwanted dithering. I recommend viewing the animation's images at full size so you can't suspect your browser of doing averaging or dithering of the images... Sequence of Images in Animation ------------------------------- 1. "Warped" 2. Without "3d"-like perspective distortion. 3. Without color compression. 4. Both warping & color compression disabled. 5. Complete spectrum of the map in the image. I believe that the "4. Both warping & color compression disabled" image is the original 'unaltered' image. - Hal Lane ######################## # hallane(a)earthlink.net <mailto:hallane%40earthlink.net> ######################## > -----Original Message----- > From: Fractint [mailto:fractint-bounces@mailman.xmission.com]On Behalf > Of Niekamp > Sent: Thursday, January 15, 2015 10:02 AM > To: Fractint and General Fractals Discussion > Subject: Re: [Fractint] Warp Effect Demo > > > Am 15.01.2015 um 14:12 schrieb Hal Lane: > > With your permission, I'd like to make an animated > > .GIF that automatically does the stepping thru > > your images and make it available on the list. > Brilliant idea! > Thrilled... > Petta > _______________________________________________ --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com

Bluebird Feeding

Don´t know what they are fed but they seem to like it! ; On every, even a very small change I set the latest date and add a short remark about the reason. Today´s again has no influence regarding the generation but makes the warpeffect a lot easier to handle - just type "0" instead of the compression factor and only the function is used. Type "ident" as function and only the compression is used, like in today´s image. If the settings are created in two stages there are far more versions and they are easier to predict. The secant frm used is so sensitive that even a small compression alone results in a different image. ; https://www.dropbox.com/sh/sz6of739tbph100/AAAK9R_I2dnMyVgwHpQSDM6Aa?dl=0 ; Petta ; ----------------------------------------Start Par------------------------- 10008-14 { ; Bluebird Feeding ; Secant-Magnet ; Time 0.08.04.66 Reso 1280/1924 ; Map SG14 - Fac (=Maxiter) 2048 Compression only reset=2004 type=formula formulafile=mfr_13.frm formulaname=multifractal_13 function=ident/sin/cabs/sin passes=t center-mag=-0.128355/-0.0118769/1.335962/1.4286/90/-1.23373533611470521e\ -014 params=1.123456789123456/0/10008.04595700012/50402.0506030602/152048.040\ 4808001/2048.1604894022/0.00482003595/256.30000000212/384.1000003001/64.\ 10000030010001 float=y maxiter=2048 inside=maxiter periodicity=0 rseed=-2436 colors=aAENij<9>CNXBLW9JU<3>5AP<3>77D86A857944A31<4>A95AA6AC7AD8AE9<4>DM\ FEOGFQHFRJGTKHVLHWNIYOJ_Q<3>KcOKdNKeNKfMLhL<6>enAho9kp7<3>wt0<6>Zf7Vd8Sb\ 9<3>DVE<4>CPBCNACM9<2>BI8BH7BH7<3>AE69D5DE5<3>UI8YJ9aLAeMBgOCjQE<2>nVI<3\ >vdAyg7yh4yi2<14>yugyujyvm<2>yyvzzyxwv<9>bRR`NOYKK<2>SABP67P67<18>aBGbBG\ cBHcCHdCIeCIdCHcBGbBE`AB<3>X85W74U62<21>sjStlTunU<2>ytYzvZyvZ<24>ZulYumX\ um<2>UuoStpRro<2>Okk } ---------------------------------------------End---------------------------

Petta, Many thanks for posting the series of images showing your warp effect and color compression. While I was viewing your demo images one after another in the same window, I realized that they were computed at exactly the same point in the XY plane. So, as I was stepping thru viewing them, they were effectively sequentially overlaid on top of one another. This showed the change in appearance of your fractal due to your applied effects quite clearly. With your permission, I'd like to make an animated .GIF that automatically does the stepping thru your images and make it available on the list. However, I missed getting your image from Jan 6 that you mentioned. The version of your Jan 6 image "Round Trip" that I calculated: http://www.emarketingiseasy.com/Albrecht/MFR_13/150106_Round_Trip/A1501061.G IF doesn't correctly overlay on your other five images. Can you send me a link to your Jan 6 image please so I can try and include it in the animated .GIF if it correctly fits into the sequence? Thanks! P. S. I like the concentric ovals of butterflies with their wingtips touching in the image I calculated... - Hal Lane ######################## # hallane(a)earthlink.net ######################## ------- Forwarded Post ------------------------------ Author: Niekamp Date: 2015-01-14 02:46 -500 To: Fractint and General Fractals Discussion Subject: [Fractint] Warp Effect Demo I cannot understand why nobody seems to be interested in the improvements I have added to my software and Fractint as well. Maybe because you think they are only allegations. Or more likely: people tend to notice details that are wrong - if they have vanished they only see a better result. ; Therefore I take the oportunity of a demonstration and some explanations. I use the image you have seen in my post Jan,06, SG color map and in 5 versions. 1. The "warped" version 2. The version without the "3d" like perspective distortion. Of course this is visible only if there are rounded objects or strings of self similar objects to supply a roomlike vision. 3. The version without color compression. This can be adjusted according maxiter and bailout. 4. The version where both are disabled which is the same as without warp effect. 5. The compression factor is identical to maxiter so you have the complete spectrum of the map (or multiples) in the image. The effect can be applied separately to each participating frm, so up to five times in a single image. ; In the folder you also find the par files and the input table to locate the settings (PDF, Doc or JPG). ; https://www.dropbox.com/sh/je2s3oa0sb3fdl0/AAAg9Z6rPv-cMbUXjE5TtIk0a?dl=0 ; A note about security: Since about 5 weeks there has not been a single malware attack on my XP computer. The reason is improved Xmission security (Thanks Tim!) and the perfect 3 way protection of Bitdefender (Traffic Light, Quick Scan, System Protection) which is free, easy to use and silent.

I love this image as it shows the full power of the SG map - I call it miracle map - with the full spectrum, all colors flow in 3d manner and have the same size and all details have a defined 3d like shape that will be even more detailed after anti-aliasing.

Sure! It's calculating as I type this. But it will likely take a couple of days, as I always use Single Pass at 3k x 4k as part of my anti-aliasing process... Some good news is that I've ordered a new computer, so the possibility that I can calculate one Fractint image per CPU core looms tantalizingly close... I'll report on my experience with this.

What you have not noticed is that in addition to the 3d like perspective distortion there are no steps in the coloring anymore. The colors change with every pixel !!. As far as I know this has NEVER been watched in Fractintint 16bit images This is made possible by the color compression which can be adapted to the iteration and bailout settings - principally the color changes with every iteration. To get the full aspect I use Sylvie GalletÂ´s fabulous 3d maps - now the full spectrum is available in a few lines, so even very samall objects show this effect.

MapZ
by JackOfTradeZ＠comcast.net 14 Jan '15

14 Jan '15

. Well, after requesting and then downloading Sylvie's "3D" maps [thanks for the links!], I found myself in the same situation of having to manually load each map into an image, inspect it, save or not, etc. For dozens or hundreds of maps?! I'm getting to old for that - no more!!! So I remembered some old DOS stuff from the good old days; should have thought of this long ago! Now if you have a fractint image and you want to see how it looks in any number of different maps to select the best one, do this: 1] display the image in fractint, then hit the "B" key and save it to a PAR file with a name, etc. 2] example, the file is called NEW.PAR and the image entry is named STARZOOM. 3] and in this single directory you have ALL the fractint files and ALL the maps you want to check out 4] create a simple ascii text file (like in notepad) and put in it this one line exactly as it is: for %%f in (*.map) do echo FRACTINT VIDEO=F8 @NEW.PAR/STARZOOM MAP=%%f SAVENAME=%%f BATCH=YES >> maptry.bat 5] save and name that text file anything you want, but it must have a BAT extension. 6] run it from the command prompt in that directory 7] it will generate another file called "MAPTRY.BAT" , and it will have a line for each and every MAP file that is in the directory, like this: FRACTINT VIDEO=F8 @NEW.PAR/STARZOOM MAP=SGG101.MAP SAVENAME=SGG101.MAP BATCH=YES FRACTINT VIDEO=F8 @NEW.PAR/STARZOOM MAP=SGG100.MAP SAVENAME=SGG100.MAP BATCH=YES FRACTINT VIDEO=F8 @NEW.PAR/STARZOOM MAP=SGG099.MAP SAVENAME=SGG099.MAP BATCH=YES FRACTINT VIDEO=F8 @NEW.PAR/STARZOOM MAP=SGG098.MAP SAVENAME=SGG098.MAP BATCH=YES and so on. 8] Next you must remove the ".MAP" entries; I use a simple search and replace program I downloaded from compuserve 20 years ago and still use. Replace ".MAP" with a space character " ". So you get this: FRACTINT VIDEO=F8 @NEW.PAR/STARZOOM MAP=SGG101 SAVENAME=SGG101 BATCH=YES FRACTINT VIDEO=F8 @NEW.PAR/STARZOOM MAP=SGG100 SAVENAME=SGG100 BATCH=YES FRACTINT VIDEO=F8 @NEW.PAR/STARZOOM MAP=SGG099 SAVENAME=SGG099 BATCH=YES FRACTINT VIDEO=F8 @NEW.PAR/STARZOOM MAP=SGG098 SAVENAME=SGG098 BATCH=YES 9] Run that batch file in the directory; fractint will create the image from the par with the given map, and save it as a gif file named for the map! Then you can look at all the GIFS in any windows graphics viewer, or from fractint one at a time. This is a quick and dirty technique, I thought I would share it for all interested. I am trying to refine this so you don't have to manually search and replace the ".BAT" entries, but I haven't figured out how yet. Cheers JoTz . .
