IBrowse 2.5.2 / AmiSSL 4.4 and Images…..

[duga]

There's a problem with either PNG or JPEG (or both) in 2.5, 2.5.1 and 2.5.2 (but not in 2.4).

I'm using datatypes instead and the problem is gone.

Someone who bothers can try to replace one at a time to find which one is the problem.

Hi duga, thanks for the info on the other versions of IBrowse! Yeah, WarpDT datatype sets really seemed to help. I was installing them one at a time but did not find one for GIF images. Which one are you using for GIF images, if I might ask?

For GIF I use the internal iBrowse function. I only use datatypes for PNG and JPEG.

Ladies and gentlemen: I can confirm the problem is located in the internal PNG renderer. The internal JPEG renderer is fine.

Really?

1. Can you post an example URL of a PNG image that won't load?
2. What is the error message that pops up with the mouse pointer over the placeholder?
3. What does "version cybergraphics.library" say on your system?

The pictures are _loaded_. The problem is that the pictures are severly garbled with the internal PNG decoder/renderer. Have a look at https://safir.amigaos.se/main.php and you should see the problem.

System:
A1200 AGA
Blizzard MkIV 1230/50 MHz (no FPU)
Roadshow68k
MUI 5.0 (tried 3.8/3.9/4.0 too)
SSL 4.4

I'm using MUI3.8 on the A1200 in my sig with no problems. However, I have just the opposite problem with PNG images. Garbled if I use WarpPNGdt - fine if I use internal PNG. I'll stick with internal.

What does baffle me (to some extent) is how slow AmiSSL is. Using my other A1200 with MUI3.8, an ACA1233N w/o FPU & 128MB mem, IBrowse 2.4 & AmiSSL 3.6, amiga.org still load in seconds. Using my A1200 with a GVP Typhoon 030 @40MHz w/FPU & 64MB mem, amiga.org takes some minutes to load.

Both running OS3.5, internal images and same connections parameters. I really don't want to buy two more licenses till I get this sorted.

But, thanks so much for all your help Oliver!!!   .  Finger crossed!

Same iBrowse and AmiSSL versions on both systems? I assume the memory is much faster on the ACA than on the Typhoon.

Ok, so AGA. It's just that several different issues appear to have been mentioned in this thread.

Try turning "Use Fastmem for images" on in the image settings - it should be ok then. I shall find out why the garbled images appear with that setting off, although I can see it is not all PNG images (probably just those with alpha or transparency).

Use Fastmem/other mem was already enabled. But if I disable it (instead using Chip mem) the problem is actually solved. But in that case I prefer using fast mem and the external PNG Datatype. Anyway, thanks!

Actually, there is something that can help - IBrowse 2.5.3 will hopefully come with a SSL session cache (currently being tested). IBrowse never cached SSL sessions, but seeing as OpenSSL has a cache feature, it is time to make use of it . Certainly, not much can be done about the initial handshake, but the cache will allow this slow process to be skipped for subsequent connections, which makes things much faster on OS3.

Great! I want to report an issue, which did not exist in 2.5.1 !

I use a http-Proxy, which works well, but if I click a link, it allway wants to connect me with the https-Site instead of http ! This did not happen in 2.5.1 ! I allways have to correct the link from https to http ! Please have a look Thank you!

Are you sure it's not changed on the website/server? Https shall have priority over http.

Agreed - that is certainly not what should happen. Does the same happen with IBrowse 2.4?

Can you give me a little more info about your system? It's AGA and presumably you have no graphics card available? What OS version are you running? And finally, what does "version cybergraphics.library" say?

I've been running some tests on this and discovered that, on my OS3.1 AGA boot (no CGX), PNG images look fine in IBrowse 2.5, with fast mem images off or on, and using the internal decoder. If I boot to my BVisionPPC and open IBrowse (2.4 or 2.5) on an AGA screen, images are messed up only when use fast mem for images is off. And it is only images with transparency/alpha that are corrupt.

Sorry for late answer. I have the same problem (fast mem used for pictures causing garbled PNG graphics) on another A1200:

System:
A1200
AGA
ACA1221
AmigaOS 3.1.4.1
MUI 3.8
iBrowse 2.5.2 demo

No external datatype installed. Using chip mem for pictures = problem solved.

Does IBrowse 2.4 exhibit the same issue? And do you have any patches installed that affect bitmaps (I'm thinking things like FBlit)?

Now matter how hard I try, I cannot get 2.4 to show the same problem as 2.5.2.

No ugly patches such as FBlit etc. installed.

Good - at least that probably rules out OS 3.1.4 as being a factor, which was going to be my next question.  How about IBrowse 2.5 (the initial release) - does that have the problem too?

It is a little strange (and annoying) that I cannot reproduce the problem here.

As I wrote in https://forum.amiga.org/index.php?topic=74567.msg848138#msg848138 , the problem started from 2.5

Not sure what the next step is.

Thanks for your patience duga - having re-read the entire thread, I now realize that I have been repeating myself a lot!

Going back to the https://safir.amigaos.se/main.php site, I can see a problem too on my AGA boot. I presume that some of the PNG files look fine (e.g. the header/logo at top/left and the news item images), but it is all the table/page backgrounds that are not shown correctly? That is what it looks like here.

No problem. It's easier for me to be confident that the fault is in the program now when I have two functional A1200 with different CPU's and OS versions.

Yes, it sounds like you see exactly the same problem as me.
