Why the deadline?
Homework help? BTW: 2PM is meaningless. Which timezone? Which day? |

Please don't fill up my thread with garbage, fillers will confuse those who are looking for the same algorithm. If you don't want to help then stay away, and stay 1,000 miles away.

NOW, people, let's get down to business. Any examples? Saving from a bitmap in memory to a png on disk. and then maybe the reverse, from png on disk to bitmap in memory.
Faster the better, even faster is even better, THE fastest is THE best. It's up to you how good quality it has. Bring it to the forum and show it off. I can't believe how little material there actually is in the assembly world when it comes to PNG files. Personally, It's just wrong that every asm programmer should make his own PNG library, it's wrong. This is the very reason I'm requesting your hand, and it's a great hand, show it's capabilities off and let it loose. |

yes i do have an example, but i will sell it for 1000euro.

People, let us bring the forum back to it's 90's glow where it shined freedom, and not money.

People, my definitive friends: If you post an example, keep in mind that I appreciate short ones.
Thank you. _________________ Do you think anyone will sell their soul over a 10 cent yoghurt with a bad after taste that lasts, a decade? |

I've a brief example of building stb_image and used it to display a PNG.
You can build stb_image_write similarly and write PNG files. (Note: Tests have shown that the Windows decoder is faster than other libraries - that is not the purpose here.) I've also made a PNG writer with fasmg. _________________ ¯\(°_o)/¯ “languages are not safe - uses can be” Bjarne Stroustrup |

It's not strange that Windows decoder is faster MS have started to use Rust programming language, it just piles out the best code ever.
Rust is to HLL languages what fasm is to assemblers. It produces tight, small optimized code, in minimized form. Ok thanks buddy, I will check it out. |

Personally, I engineered a modification of QOI specifically tuned for an assembly implementation. It's close enough to PNG and super-fast/tiny. _________________ ¯\(°_o)/¯ “languages are not safe - uses can be” Bjarne Stroustrup |

For the sake of having it in the library, does anyone have a GDIplus version of the routine?
I think people will love you if you post it here. Yep, fast PNG is very important, rendering videos is heavy duty work. Maybe it is QOI I should use, it's perfect for video rendering in assembly. |

If you search for madmatt's examples - he did a wonderful array of GDIPlus examples. I haven't felt a need to duplicate that effort - if you've used one COM interface - you've used them all, lol.

I have used GDIplus about 15 years ago

Overclick, bypasses GDIplus and uses WIC to load a PNG. GDIplus image support comes from WIC.

So it's a wrapper, I wonder which layer will be rendered obsolete first. But it's a useful have.
Ali, even if your routine is worth nothing, you can still post it for evaluation, this is a PNG thread and we must have them all. Don't be shy or afraid to post it. I would like to see as many people as possible post their private PNG code in here for everyone to use. Hurry up because we are living on borrowed time, AI is taking over soon. _________________ Do you think anyone will sell their soul over a 10 cent yoghurt with a bad after taste that lasts, a decade? |

MadWizard wrote: This library allows you to decode and display PNG images in your applications. The library is very small and has been written in assembly (MASM32). The library supports both interlaced and non-interlaced PNGs, in all color types mentioned in the PNG specifications version 1.0. The library is easy to use, has detailed documentation. Includes and headers are supplied for use with MASM32 and Visual C. _________________ ¯\(°_o)/¯ “languages are not safe - uses can be” Bjarne Stroustrup |

MadWizard, I will check it out. You know the mad wizard, he is the real deal. It's probably smooth as butter. I wonder if he has more nicks. Some people build entire libraries with 50 nicknames.

Is anyone willing to convert MadWizard's PNGlib to fasm?
Someone could convert it while others could post their own PNG code. This is a PNG thread, everything is useful. _________________ Do you think anyone will sell their soul over a 10 cent yoghurt with a bad after taste that lasts, a decade? |
