Making .BMP images from scratch

[@UliTroyo]

I had no idea we were going to get this cool this quickly. Images are exactly how I got into C!

[@neoeno4242]

Always good to get to the cool stage 😎

[@w花b]

Yeah, found some GitHub repos explaining how PNG worked and tried reading random PNGs from the internet to verify if it was accurate and tried building my own. The Huffman stuff was a pain in the butt to understand though.

[@theoriginalneckbeard]

I just fell in love with your approach. One of the last Tech-KZbinrs providing actual in-depth information on interesting topics instead of clickbaiting you into surface-level topics that other KZbinrs already talked about a week ago just to grab some clicks.

[@jumbledfox2098]

i think i've left a few comments on your channel before, but you're such a good teacher, your videos are so hard to stop watching and you really inspire me to keep going with my computer science stuff, thank you!!

[@akramdiafat9380]

I have never understand something that quick without pausing the video To much,You are truly a good teacher

[@kestergreen3844]

You're an amazing tutor. The information you teach is more easily understand because you use graphical stories whereas others use some b-roll. Your endianness example was spot on! Go hard with the video editing juice! :)

Thank you for your videos and clear articulation. I’m new to all of this and it’s so fascinating.

Ooh, Charles Petzold’s Programming Windows, that brought back memories. Where I learned the message loop and event driven programming. Good times.

[@script_sh]

That’s a pretty good video! Clear explanations in a non-exhaustive way. 10/10 I keep following this series and future others 😁

[@__hannibaalbarca__]

Good❤, KZbin post me this video. I do it many years ago, you remember me that days.

[@Sandromatic]

I think what genuinely helped me understand endianness is to really think of it as an arbitrary choice, by arranging bytes vertically. This means that bytes arent arbitrarily looping back on themselves and the bits aren't in a weird order but instead you have to arrange things in such a way. Since you can't retrieve info out of memory in any unit less than 1 whole byte, this means that you can consider bytes as a unit without being biased in such a way. It's also kinda important to consider it as just an address ordering rather than a fundamental way it's ordered in reality. It also makes total sense for networking to be big endian though, because over a serial connection, the bit *is* the fundamental unit, and transmitting things in little endian byte order but big endian bit order would just be ridiculous.

[@emmeryncariglino4983]

18:27 ok that's how i'm describing that flag from now on. ok but in all seriousness these videos are helping me get over burnout from my last tech job and i hope they continue for quite some time :D

I like your c videos so helpful for beginners. I myself started with implementing image format but instead it was a qoi format, it's quite ok and quite elegant/simple to follow (also spec it two pages)

[@neoeno4242]

QOI actually looks really cool! Thanks for introducing me to it 💙

Great stuff, inHex was a little discovery for me, thank you. Doing exercises, there is slight difficulty displaying colours on Windows using Debian wsl with watch. I had to use poor man's watch "while true; do clear; make run; sleep 0.5; done".

[@gamedevlife9950]

Hi, loving your videos. Just want to point out that the free_bitmap function at 13:46 will not actually set the bitmap.pixels pointer to NULL, as the Bitmap struct is being passed by value to the function. But great video overall, keep up the awesome work!

[@DingBatCrazy]

This is true. Just to elaborate, the function should be updated to ``` void free_bitmap(struct Bitmap *bitmap) { free(bitmap->pixels); bitmap->pixels = NULL; // Now this affects the original bitmap in main } // then in main.c free_bitmap(&bitmap); ```

I’m Impressed by your knowledge, kudos. This is a very interesting learning video, thanks for sharing. I’m approaching the world of coding and wanted to ask which kind of advice you wanna share regarding the topic to someone that is a beginner. Also, how have you started programming?For how long have you been doing this? Thank you for your time!

I love this course, I wanted to ask how you came to learn these things - is it from years of tinkering or was this something they teach in college courses?

[@neoeno4242]

Thanks! I'll answer this one in my next video - but briefly, years of tinkering. I didn't study CS at college though I started as a teenager.

[@valinor3317]

Actually learning WebGL and make graphics with Maths so check this will be useful. Thx!

Please can you provide a download link for that hex editor you used to create the bmp. Thanks.

Like at 13:02 ? That's an Excalidraw diagram on the left and VS Code on the right. I will say the Excalidraw-diagram stuff in this video did take quite a bit of editing work to get right :) I think enough that I might develop something custom soon...

[@JohnDoe-el8tg]

[@catafest]

do you test with FASM assembly ? can you make a video about tools you used ?

[@neoeno4242]

Thanks for the comment! Not done anything with FASM assembler yet! Next video will be on assembler though I'll likely be sticking to the LLVM & GCC assemblers. I use quite a few tools and try to explain a little about them as we go through - so one video would be a bit of a challenge - but if there are any that you'd particularly appreciate more focus on please do let me know! I can add it to the list.

[@salim444]

3:48 if you write memory addresses from rught to left then little endian seems more intuitive. I know it is not the point of the video just thought I need to point that out

Honestly I work with this things everyday and never consider casting scenarios in little vs big endian

[@aquahoodjd]

I like my computer science teachers approach to walking up to the light switch and turning it on and off I'm saying this is a computer and what it's doing but very very fast. I ended up finding a loophole in my undergraduate regulations as I was a philosophy major at the time and even though I had a lot of computer background and had always had a computer including a BBs the medieval period of computing but yes play i was programming in basic. Which is the creation of agents and combining different open source can you eat machine learning algorithms of different architectural type be at large language models are convolutional neural networks... But the issue is that the specialization in one area doesn't necessarily translate into the specialization at a low level as you're more or less working at compared to where I am but my entry point was more data science and statistics I took a relational database replacement for foreign language requirement never understanding that I would actually end up a dual citizen living in the German speaking part of Switzerland after having spent a decade learning French in the French part so now I have to start over and to learn Swiss German. But if you're interested in hearing what I'm working on and if that interests you let me know.

Loved this video. Devoid of politics. I watched a CNN news report on an 'expert' reporting about two photos and if they had been 'altered', the expert pointed out the meta-data had not been altered, just the filter. I had to laugh, the IMF, CIA, NSA, MI5, MI6, MOSAD, FSB, etc all know how to change the meta data (or strip it) - probably their lowest level personnel learn how to do this on day one. Note: I don't know how to do it. As a joke: IMF is Mission Impossible secret organization, Impossible Missions Force (IMF). headed by Tom Cruise.

[@anon_y_mousse]

I'm assuming you're making a joke when you say you don't know how to do it, but if you really don't, then I suggest you look it up because it's super easy, barely an inconvenience.

[@aquahoodjd]

You're essentially describing hexadecimal format correct?
