JpegViewer needs rework :)

[Horscht]

Hi

the jpegviewer of ule realy needs some rework. Zooming is realy akward.

Taking a comic page as an example.

when opening it, you see the image centered on the screen. Zooming now causes the image to zoom only within the boundaries of the original, centered image.

If I have a comic page for example, the image takes half of my screen, something like this:

--------------------------------------------
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
|             |               |            |
--------------------------------------------

when zooming now, the image stays the same width, i.e. still half of my screen, but now to see the picture in it's full width (height naturaly gets cut off), I have to move the picture left or right (back and forth, depending on what part of the picture i want to view).

Instead of doing this, the pciture should "grow" until it reaches the full width of my TV.

This would be a realy usefull change and make the jpegviewer a lot more usefull than it is now.

alternatively, is there another decent slydeshow viewer? I tried myPS2 as well, but that made text on comics unreadable, and additionaly doesn't allow going right to the next picture without going back to filebrowser first

Hey.

You are really comic.

If you don't like jpgViewer, try to make better with 32 Meg of ram.

Best regards

Polo

I am by no means a developer, but to be honest, I think what I am proposing here is very feasible with 32MB of RAM.

Maybe I am not able to express it properly, though.

I will provide a proper illustration tomorrow or on wednesday

I agree. It would be better if it worked that way.

However, you should remember that the JpgViewer was never intentionally planned for uLE. All we intended to implement was a simple JPG load/display routine sufficient for the uLE skin and possibly a preview. But when Polo35 donated his code to use in uLE it already contained a version of the JpgViewer pretty much the same as we use now (some minor changes were made later). And that is the only reason why the JpgViewer in uLE even exists.

No.

Hey Polo, don't be too hard on him. He probably means well, but like most non-programmers he doesn't realize the difficulties of graphics processing with too little RAM.

Well, not being a developer he obviously can't do that, but to be honest I think that you could do it.

I just don't think it's necessary, as you've done enough for uLE already, and to make the zoom of JpgViewer work more nicely, expanding the zoomed picture width/height to full-screen when possible, would clearly require a lot of work. So it would probably not be worth your effort. And the methods needed for an improved zoom with a small RAM 'footprint' might also become too slow to be practical.

IMO your current efforts for the PS2 are better spent on the VMC stuff.

To be honest, my current efforts for the PS2 are currently for HD_Gui, but i promise to take a look to vmc when i finish HD_Gui improvements.


Oh, and i remember this ??§§!! zooming function.
The problem was that i loose ratio when picture reach full screen.

Sounds like something I can take a look at, where is the source? SVN?

But what is the purpose of jpegviewer? Doesn’t it already show JPEGs?

Of course not.
As for all subprograms of uLE, the JpgViewer sources are found in the uLE release packages.

Of course it does.
This thread only relates to how the 'Zoom' feature is implemented in the current JpgViewer.

I agree to this as well. I was going to bring it up but I knew people here who programs have a lot of things on their hands so I left it. But since someone already brought it up. I figured I should say something as well.

I also use uLE JpegViewer to read digital comic books because it is probably the best easiest jpeg viewer software out there. I have MythTV (linux PVR) and used window jpeg viewer and such. but none of them could even compare to uLE JpegViewer and offered such flexiable features especaily with controller. where i could shift to next and easily move the jpeg. only thing bothered me was the sides not being able to show.

i do realize it wasn't the purpose originally. but i dont think it would hurt to try widen it. would be really great if it was doable!

Really?
You mean you couldnt zoom in using Windows Picture and Fax viewer?

I use it all the time and only images that arent of quality high resolution, tend to pixelate when zoomed in, but it would be the same with any viewer on low quality resolution images, i would imagine.

The quality part was not the issue for me. Especially when it comes with comic strips which usually comes in lesser quality. I was not talking about that or not being able to zoom. I know alot of programs can zoom. but i was speaking of how flexible uLE JpegViewer to view and move around and shift back or next pages with just controller. Espeically when i can read on bigger screen while sitting on my futon. more confortable rather than sit on chair front of computer desk. Those reasons were what i liked the most. That is why i hope someone figures out and decide to widen the zoom screen on the sides.

first of all best regards to all are involved in developing of ule ....
great work dudes ....
i found a bug in ule .....
when i try to rotate the image in left or right it seems to be all ok ...
but when the image rotating up ''reverse'' the display print a strange lines and artifact ....
i browse the pic's on my hd usb mass storage cd dvd mc and the result is equal

this bug appears after the version 4.12 ....


ciao a tutti and sorry for my bad english .....
