Fast picture viewer for AGA - Page 2

Rebel-CD32 · 29 January 2010, 05:58

The new v program is definitely faster than Visage by a few seconds at displaying the same image. It wouldn't display the 1024x768 image in HighGFX resolution though, which is a shame because other picture viewers use this mode if it fits. Hopefully this'll be fixed in future versions, it's nice to have a new, faster picture viewer for classics available after all this time.

I'll ask meynaf if this is somehow implementable. By the way, is this handled through a standard monitor file? And also, is it a planar GFX mode, or a chunky one?

HighGFX is just another monitor driver for AGA that requires a very special type of monitor or an Indivision to display the screen. It's what I use for my Workbench and any applications that let me choose the screen mode. When viewing images with Visage, PPShow or Multiview, they pick the best fitting screen mode so a 1024x768 image always ends up on a HighGFX 1024x768 flicker-free 18bit display, which looks beautiful. It's definitely a planar mode. The HighGFX driver is available on Aminet if it'd help.

I will have a look at HighGfx driver to see what I can do.
But I don't have the relevant hardware...

If you have some pictures it should display but doesn't, please give them to me. My viewer is a bit intolerant about badly encoded images

About versioning, the link on free.fr contains the last version.

If you have questions about HighGFX you can ask Ratte of course.

nujack · 01 February 2010, 17:37

@meynaf: You don't need a gfx-card for HighGFX-resolution. And yes it would be cool if your PictureViewer supports HighGFX. I have tried out your PictureViewer and I was surprised how fast it is.

daxb · 01 February 2010, 21:28

A feature like bestmode (screenmode) would be fine.

meynaf · 05 February 2010, 10:36

Well, I don't exactly see what I have to do.

What I need is code to open intuition screens of whatever dimensions, including those which don't have square pixels (e.g. to show WB grabs).

Do you say I should perform some sort of GetBestModeID() call ?

My code must remain generic because it is reusable, but if I manage to make it work, other programs (e.g. my HOMM2 port) will benefit of it.

On the other hand, I'm not sure it can remain as fast as it is if 28Mhz graphics are used...

Hi,

I use Visage because it allows a lot of functions in it's tooltypes, eg: scale which will scale the pic to your monitor screen.

Also, Visage pre-loads the next pic (if also selected for viewing) in the background so there is little or no time delay in displaying the selected pics.

Regards, Michael

About how to code that stuff like bestmode (several pic viewers have such a function) alas I can`t help you. If you are interested in you should ask in the coder section of this forum. However, the interesting screen modes are DBLPal, Multiscan and maybe SuperHighRes.

yes....visage and fastview preloads the next pic.....I think this feature is essential to add in the new program V

meynaf · 08 February 2010, 09:47

But Visage crashes any time I try to show a PNG, and its display of progressive jpegs is awfully slow.

Pre-loading and scale were already in my todo list, but I have too many projects and I lack time...

As I'm giving sources with the program, can't anyone help ?

Can you give an example PNG picture and how do you call Visage? I would try to reproduce it here.

Every possible PNG picture will do, and the way to call it is unimportant (I used cli).
But you have to try it on a 68030 without fpu.

daxb · 11 February 2010, 13:41

Can`t check on 030 because I own only a 040 but did you checked the requirements part of visage.guide (libs, fpu, no-fpu version)? There are several tooltypes/arguments for PNG, for example you should try DATATYPES, NOPNG, ... to find out if the internal PNG reader or datatype/library is responsible.

This is no fpu version, and fpu is totally useless for png anyway. Other formats work fine, btw.

It's clearly the internal decoder, not any datatype (akpng crashes happily too, but it's another story). IIRC error is 8000000F. Easy to read signature

You're Visage author, aren't you ?

I just read about PNG and FPU in the Visage.guide. The math#?.librarys are also used. One used by PNG reader.

No. The author is Magnus Holmgren (Sweden). Check guide for contact address.

Math libraries are not needed for PNG. If they are used, then a mistake has been made somewhere. Believe me, as I wrote my own PNG viewer.

I asked, because you behaved like if you were him

so I assumed that you got that version
have you got that 1.02 version?? can you upload it to the zone??

Version 1.02 is now available on meynaf's link and WT page.

Sorry, it seems my english is too bad or my interest is to high.
