Re: Squares

Indeed. This folly should be blocked, at this point. It's not good for anyone, especially for albert

Re: Squares

Sincerely, at this point I think he should be banned. He brings zero contribute to the forum, and he clearly hasn't learned anything from any answer he received from other users. We are running in circles, and it seems to go on since ten years! At this point, either he is trolling (and then he would...

Re: Squares

Albert, do you accept a bet?

Something like: if your formula works, I'll stop replying to you, forever. If your formula can't be decompressed, you will stop posting anything about compression, forever. Deal?

Re: Squares

Are you serious? Are you suggesting that developers of a compression software would deliberately hijack their own software so it won't work? Are you suggesting that it will steal your code, although you admitted that your code never worked? (so why anyone would want it?) Are you suggesting that, des...

Re: Squares

Albert. Stop. Please, STOP. We tried to explain it in every possible way that it can't work. There is a very well written wikipedia article here https://en.wikipedia.org/wiki/Lossless_compression#Limitations that explains why it can't work. You don't believe it? Fine. Keep trying, if you want. But p...

I see. Well, bad news for you: compressing an already compressed file is mathematically impossible. I tried to explain it to you in the past. If you don't believe me, do what you want, but you will get disappointed

Re: Squares

@angros47 I think walking down a virtual isle filled with items would be a good idea.. Other people thought the same, before, and tried it. In the end, customers preferred more conventional sites. So, it doesn't matter what you think: that solution was tried, and didn't work. I spent 10 hours today...

Re: Squares

It has been already tried several times, in the past, using StreetView for internals, and earlier, using flash animations, or 3dml or vrml sites. It has never been a winning solution. After all, if you are looking for a specific products, would you prefer to click on it, or to navigate to it in a vi...

Re: Squares

That run-length encoding , won't work on a string of random characters.. Nothing can work on a string of random characters. The only thing that can work, if the string is REALLY random, is to just store the length of the string, and during decompression you reconstruct a string of the same length u...

Re: Squares

Yes, Albert, I have an idea: and the idea is that you should drop compression algorithms. You lack the theoretical knowledge, and without it, you are unable to understand that your approach is totally, absolutely wrong. It won't work. It can't work. It's less likely to work than faster than light tr...

Re: Squares

The outline effect can be done using a convolution filter (I made one in FreeBasic here: https://freebasic.net/forum/viewtopic.php?p=199321#p199321 ). Basically, it subtracts the value of a pixel from the average value of surrounding pixels: in that way, if the pixel is on a plain part of an image, ...

Re: Squares

Since all binary values above 0 start with a 1 , you can exclude the leading 1.. and it compresses 90% to 99 % But how do you tel how many zeros are in front with the 1 gone??? There could be 7 zeros , and 3 bits added to the formula doesn't compress.. You don't. That's why no compression algorithm...

Re: Squares

You are talking about lossy compression. To do that, the algorithm is supposed to be able to find "essential" parts of a dataset, and to discard non essential ones. This is surely possible, but it works only for specific datasets (for images, or for audio clips, for example). Albert stated...

Maybe i should start a "me only" topic , to post my trig-doodles and code snippets.. and crazy ideas... Or maybe you should open your own blog, and use it for your ideas, instead of using this forum. So you would be allowed to pick every subject you want, even if it's unrelated with FreeB...

Re: C++ ABI Compatible?

The constructor does not fill in the vtable, because two instance of the same Type refer to the same vtable location in memory. The vtable is created once for each Type. The constructor only fills in the vptr of the instance to point to the only vtable defined for its Type. I didn't know that. That...
