Hi all,

If anyone has working code for any of the above image formats that they could share for the web browser development, could they let me know?

I have already had an offer of PNG code for masm, and have source code for JPEG in C, but they require porting effort. Any offers of Menuet usable code or help with porting would be appreciated!

Thanks,

Mike.

I will post it here in the next two hours .


It works but isn't stable if you try to resize the view window it will hang up if you try to close the window.

You can email it to me if you wish:

Gimp source code is frealy available at gimp.org it may be a good start to get some coding ideas for multiple graphics format. The source for gimp, i think is still included in *nuxs releases. so some of you may have it already if you have a *nux version.

I have no problems getting sources for image decoding or rendering, thanks. what I am looking for is code that runs under Meneut, to help save us time in developing a web browser.

I'm now just looking for PNG and GIF decoders now.

Thanks to everyone how offered assistance.

Mike

Here is the fixed version of your application.

Thanks again,

Mike

I've started working on a png rendring software. I'll post code in a week or two.

Better download jpegview 0.13

See http://www.meosfiles.narod.ru/giflite2.7z
It's a simple GIF decoder written by me.

I guess i'll start work on a png viewer, ive been wanting to write something for menuet for a while, this way i can see how menuet handles.
Hopefully shouldnt take too long, although it'll probably just end in disaster

(Oh, and how is the web browser comming along anyway?)

I think I'm going to make one myself, because pelaillo is on vacation or sth. My parser is ready and I think I'll start implementing into browser soon...

Hey Willow, does your GIF viewer work with a fixed animation speed? Don't you want to obey Compuserve and strikly display the images without delay, except an infoblock says something else?
I'm also coding a GIF-Viewer as a .COM file (MS-DOS) - just for fun. Maybe it'll end up as a bootable image viewer for floppies. *g*
Good luck with the browser - the most important app today !

Well, I can't really find the time to continue this. mainly because my machine isn't supported (amd64).
The code is absolutly uncompleted, just wanted to share it in case someone wants to continue it. I might continue it in a week or a month.
The code is also undocumented though feel free to contact me by e-mail (inside the source).

Hope this will turn out to be useful.

Where can I get information on png, jpg, gif, bmp, and tiff file headers?

eotc: http://www.wotsit.org/

Some time ago, I tried to understand the .png format (I wanted to design a specific file-format for my demo app), but the doc from wotsit didn't really explain enough to me, I can't understand the compression scheme in .png. GIF has a lot of explanation, but .png lacks this, or am I too stupid to search in the right place? thx

Even when I have read through both:
http://www.faqs.org/rfcs/rfc1950.html
AND
http://www.faqs.org/rfcs/rfc1951.html
I can't understand how the decoder should act. There are like 3 sentences about what one should do with IDAT section.

Why I chased down these documents in the first place is because I wanted to upgrade Jaguar's PNG-viewer (it lacked unpacking). Then I tried watching what the @RCHER did with that section, but then my mind blew up . I was so confused about significant bits & bytes etc.

If you can - please post here a clearer document on unpacking with deflate.
