This is a modification of an old one called -xfish (also called Xaquarium), that I have added more features to. - -To not confuse you (or confuse you more) I will call this modified xfish -"xfishtank". ['A rose by any other name...' and all that] - - -How is this different? I started with you basic xfish, and I kept the -bubbles (actually I re-wrote some of the bubble code, but it LOOKS the same). -I changed the rest of the code to allow any number of multicolored fish to -swim around. Each fish can have up to 255 colors, but on startup the program -takes all the colors from all the fish, and squeezes them down to all fit -into the default colormap as best it can. Any fish can be any size in -width and height. To make them look more like they are swimming, fish are -animated (Very simple 2 frame animation) [I got this idea from watching -the AfterDark fish on the Mac]. Fish CANNOT swim over each other, they -will turn around if they are about to collide. I had a version that -had fish swiming over each other, it was WAY to slow to be something to run -on your background while working, so I deleted it. - -xfishtank -help to see the command line options. - - - ********************** NEW FUN WITH FISH ********************* - -Since the original version, I have received various comments and bug fixes. -This version I know runs on SGIs running 4.0, Sparcs running 4.1, -Decstations running 4.1, and RS6000s running 3.1. However, there were mongo -memory leaks in the X server distributed with the RS6000, so I had to compile -the X11R5 server and use that. - -As you add more fish (especially very colorful fish) the total color use set -becomes quite large (greater than 255). I added 2 new options to help you -deal with this. By default xfishtank would find the total color use set -for all the fish you requested, and then start allocating out of the default -colormap until it filled up, it would then match the rest of the colors to -whatever colors it could get. This first come first serve color allocation -can give really bad results for large color sets. I added the -m option -to allow you to specify that the program should cut the color use set down -to the number you specify with the -m option before starting to allocate -out of the default colormap. The algorithm used by -m is considerably better -than first come first serve. Also, having xfishtank use ALL the available -cells in the default colormap can be bad. The -C options lets you limit how -many cells xfishtank will take out of the default colormap. -In the first come first serve senario colors are allocated for the fish, -in the order of appearance in the FishList file, and then from the backgound -picture if one exists. - -Finally, due to popular demand, I put back in my clipmask code. By setting -the -d option (for Do clipping), xfishtank will swim its fish over whatever -you already have on your root window. WARNING: This will slow down your -machine! The reason I took this code out originally was it slowed my -machine down too much for me to comfortably work. But if you think you have -a really spiffy fast workstation, go ahead and give it a try. - -If you use the -d option and notice some flicker (which I expect you will), -this is because xfishtank is just doing an XClearArea, and letting the root -redraw its background. If you know what you want your background picture to -be, use -p instead of -d. The image_file needs to be a gif -image. Since xfishtank now knows what your background is, xfishtank with -the -p option should have much less flicker. However, it suffers the -disadvantage that you can't change the background picture without restarting -xfishtank. - -The intrepid explorer of the source code will notice that there are some -options not described in xfishtank -help. In particular -o -and -D. These -options aren't described because they were stuff I was fussing with and couldn't -get to work. I left them in on this release so that if someone else wanted -to try and get them to work, they could see what I had already tried. The -o -option lets fish try and swim on top of each other. It looks ugly no matter -how I do it, if you can fix it, great. -D is a special option that is only -active if you have also specified -d and -p. Normally you never want to specify -both -d and -p because it doesn't make the animation any better, and it -slightly messes up fish to bubble intersections. However, if you specify --d -D -o -p you will get as close as I could get to proper fish intersections. -And when you see how crumby these are, and how slow it makes your machine -you will know why I gave up. - -Ok, I'll fess up, I'm lying, I did actually get good fish to fish intersections -but only by writing a completely different version of xfishtank that has -each fish be a shaped override-redirect window, that moves itself, and changes -its shape-mask to animate. This looks REALLY COOL, but grinds any and all -X servers to a complete standstill. - - - ********************** NEW FISH PICTURES ********************* - -This release contains a grand total of 29 fish! These fish were carefully -created through lots of hard work, and the help of many many people who -sent me pictures of fish, non-copyrighted gifs of fish, and allowed me to -borrow their scanners. I'm not going to try and name them all here, there -are lots of you, and I'm afraid I may miss someone. You all know who you are, -and you have my heartfelt thanks, I couldn't have done this without you. - - - ********************** TROUBLE WITH FISH ********************* - -There is a scarcity of good fish pictures in the world, and they are all -protected by lawyers. Here is the solution I propose. - -Any of you with talent can edit up any pictures you want, somehow get them -into GIF format, and import them into your xfishtank. The program -"giftofish" that I am supplying here takes as input any 2 GIF files, -and creates a xfishtank header file for that fish. The 2 files must have -the same width and height, and must both have the same background color. -The pictures are assumed to be the two frames of an animated fish swiming right. -Put this new header file into your fishmaps directory, edit the FishList -file to add the prefix of that header file, and increment the total fishcount -on the first line of that file. Now recompile xfishtank, and your new fish -will be used. Also, the program fishtogif will extract the two gifs from -any fish header file so you can touch up what you already have. - -Other fish sources: - The AfterDark fish on the Mac are beautiful. If you -have already shelled out the money to Berkely Systems Software to buy those -fish, and you also want to see them on your UNIX box, here is what you do. -If you can transfer the Mac fish files to UNIX, run the "gofish" program -supplied here, it will write out the fish into two intermediate files. -The files will look strange, they are my own format, just feed them to the -giftofish program (which understands that format), and it will create a -fish header file for you. - OpenWindows 3.0 comes with some fish pictures. If you have purchased -Openwindows, and want to use those pictures, the program "rasttofish" -supplied here will read one of their sun raster fish pictures, and produce -a xfishtank header file for it. Note, the Openwindows fish are only one -frame, so the won't be animated. - There is apparently a PC Windows program with some swimming fish. -The individual fish are stored in .fsh files. The program pcfshtofish -will turn one of these .fsh files into an xfishtank header file. - - - ********************** THANKS ********************* - -A really big thanks to well over 100 wonderful people who after downloading -the last version of xfishtank took the time to send me such pleasant, -complimentary, and supportive e-mail. This version was never planned, but -all of you have made me feel better about writing this code than anything -that any employer has ever paid me for. - - -As usual, mail any problems, questions, complaints, reccommendations, and -cookies to me. - -Eric Bina -508 E.
