Re: Another amazing porting...

Now I think I understand what you meant.

I'm looking at the second link but it doesn't seem right to me.

In reality the compressed data was without encoding and to bring it into the batch file I encoded it in base 64. Did I understand correctly?

Re: Another amazing porting...

Hello einstein! I hope you're doing well. Amazing work as always. Seems to perform really well on my low grade acer laptop. Thanks for sharing! P.s I haven't forgotten the 3D rose you wanted to do. Though I still have no idea how to do it, I still think it would be very fun. Cheers! Hi Icarus, the ...

Re: Another amazing porting...

@miskox I didn't understand what you wrote The data are 128 bytes and become 172 in coding based on 64. I don't think those 128 bytes can still be compressed. Maybe yes but I think that the overhead of a compression have the 128bytes exceed. But I did not do evidence. Perhaps with a compression with...

Re: Another amazing porting...

thank you steffen, I will add at the script. In the main I working at a version that use convolution for blurring the image. Its too slow for release. it uses the same data. These are datacoded in base 64. The data in bin format is very low in space. The compression is very high. Even this is data l...

Re: Another amazing porting...

Sorry steffen, it wasn't a bug but a particular behavior on fixed fonts where there were more options like 5x4 and 5x12 and he doesn't know which one to choose.

Maybe it's been fixed and I'm remembering wrong.

Then I'll check better and report it here.

Another amazing porting...

Hi to all, It's been a long time since I left the dos alone due to my bad health. A year ago I was working on this port and I didn't have the strength to publish it. I have to thank aGerman and others because they allowed me to set the fonts. If you have any suggestions let me know. I also have a ve...

Re: Why does SET performance degrade as environment size grows?

I'm doing some tests to delve into the issue of the environment. I discovered a new bug. This script populates the env first with variables whose name is of the form I_* and then after emptying it fills it with other variables of the type I*. Well, the tests lead to an increase in performance of 3 t...

Re: Dos Batch Math Library

I'm working on creating the 4 main operations (+,-,/,*) for a number of about 40 digits. but it can be extended to a larger number. I chose this number because it is equivalent to a 128 bit system. This is not a finished work, but only a first approach. For now I have implemented +,-,* and I think t...
