Merge lp:~tomasgroth/openlp/mupdf into lp:openlp

[Tomas Groth]

Support for presenting PDF using mupdf or ghostscript.

[Dmitriy Marmyshev (marmyshev)]

Looks good!
Really expecting function for us! Keep develop it!

1Q: Does it works on OS X?
2Q: I didnt get the point with PdfViewer class. Dont you use slide's system in OpenLP? Do I correctly understand that you just convert PDF to images and then show them like images? May be it will be easier to use image plugin for showing images after conversion.

And 1 more suggestion: may be it is better to use this:

os.path.isfile(os.path.join(self.get_temp_folder(), u'mainslide001.png'))

instead of this:

os.path.isfile(self.get_temp_folder() + u'/mainslide001.png')

Yea, provided that either ghostscript or mupdf is available.

I've thought of the same thing, but I have to admit that I'm yet to find a way to bend the system to my need. I'd like the service-item to be a pdf-presentation, but presenting that using the same aproach as the image plugin isn't easy. But maybe I just don't understand the structure of OpenLP yet.

I'll change this in the next push.

[Tim Bentley (trb143)]

Hum
The conversion to images is done on importing the PDF so all the images are
in the file system.
You could then add the images as image items to the service instead of
presentation file.

That would be a clean cross over Services would work as images but added as
a PDF.

Let me not to agree with this. We should not to make life of OpenLP operator (user) harder by changing visually a "PDF file" to a "group of imageses". If I (as user) add PDF presentation to OpenLP - i'd like to see PDF in the list.
Upper, I mean that create new class (PdfViewer) just to show images may be is not the easiest way, may be it is better simply to use classes from ImagePlugin to show images from PDF controller.

[Jonathan Corwin (j-corwin)]

(Note comment only, I've not looked at the code)

I too think it is nice to keep it in the Presentation plugin. The user is dealing with a PDF file as far as they are concerned and transporting the PDF in the service file rather than lots of images is in my view the correct way of doing this. Importing a PDF in Presentations and having to look for it in the image plugin would confuse many. Also by moving the PDF around it protects us from adding it on one computer with a 640x480 resolution moving to a 1900x1080 system and ending up having to deal with images in an resolution that don't scale nicely.

In the future some other app (e.g. Impress) might support the opening of PDF files and in this case the user would then be able to choose between mupdf or something else. If we're only storing the images then that wouldn't be so easy.

Yes it would be nice if we could just hook into the already existing image handling functionality of OpenLP for the display, but I wouldn't want us to tear the code base to pieces to get this to work. (I don't know the difficulties of this). I don't see any harm in making it a two phase task anyway and to do this later if we find a nice way to do it.

Finally an idea has just come to mind that in the future we could also support an "Export to Images" function on the presentation whereby we could copy the thumbnail images (created at output resolution) to the an Image Plugin group, to at least cater for those situations where the user knows the presentation application isn't installed at the destination system. However this would be outside the scope of this particular branch and would be a whole new feature.

[Tim Bentley (trb143)]

Ok so I worded it in a clumsy manner.

PDF gets added to the presentation plugin no problems. It generates images
of the pages like the presentation plugins do.

The difference suggested and echoed by Jonathan is we use the image
processing part of the serviceitem to do the displays instead of writing
and managing an 8th player within the architecture.

It will look like a PDF, quack like a PDF display like a set of images.

The changes suggested will be constrained to the Presentations plugin so
easier to implement and test with less disruption.

Adding a new player is not a small job and with the issues we have had in
the past (4 months to sort out media after 5 months getting it in) and the
migrations going on it will be a challenge.

BTW are the PDF libraries fully python3 compliant and have versions
available for all the distros we support. That would also be a merge
requirement.

[Tomas Groth (tomasgroth)]

Ok, here is some more thoughts...
The challenge as I see it is that the presentation plugin has been build around the fact the PowerPoint, PowerPoint Viewer and Impress all have their own "players", which means that since this pdf-presentation extensions is inside the presentation plugin, it is expected to provide a player, which is what I implemented in this first revision by adding the simple PdfViewer class. As some of you noted it might not be a great idea to add another "player", but the problem then is how to bend OpenLP into presenting images, even though it is a presentation...
I've looked around a bit and for now my best idea is to remove my PdfViewer class, and instead use my own instance of the MainDisplay class, which can present images. This way I reuse a "player", and avoid having to hack various parts too much. I haven't tried it yet, but I think it could work.
About python3, that shouldn't be an issue since I call the ghostscript or mupdf programs directly, not via python libs.

[Jonathan Corwin (j-corwin)]

Tim, I don't understand why adding a new player /here/ will be a big problem. Yes it was a problem for media because that was all integrated with songs, the toolbar, etc and there was a lot of overlap across plugins.

However the Presentations plugin is completely designed to deal with third party apps. All they need to be able to do is blank, and the plugin will deal with the rest. Having a simple Window that can go full screen is not going to have the problems that we had with media. In fact I personally think trying to tie this in to use the existing display would make the code more complicated and error prone that keeping it standalone.

[Tomas Groth (tomasgroth)]

Hi guys,
I've now also made a version which uses the approach Tim mentioned. It works quite well, but I haven't pushed it yet.
So how do we figure out which version should be used?

[Jonathan Corwin (j-corwin)]

Push it and get it reviewed :)

[Tomas Groth (tomasgroth)]

Ok, so I've just pushed the player-less version, where the image-presentation functionality is used instead. There is still a few issues. For example it tries to load the first image added to the serviceitem as a pdf-presentation when going live/preview. Haven't figured out why.

[Tim Bentley (trb143)]

That is because you have set the ServiceItem.processor.
You have code in the pdf route which is not needed.

[Tomas Groth (tomasgroth)]

I've now added the possibility for pointing to ghostscript or mudraw if autodetection isn't working. Also minor fixes for the pdf-presentation code.

[Tomas Groth (tomasgroth)]

Hi guys, I was wondering if you think something more should be added before this is ready to be merged into trunk? Does it make sense to make tests for presentation plugins?

[Tim Bentley (trb143)]

Looks good but these need to be fixed.

* settings screen the grouping has moved from the left side to the middle.
* settings screen "binary" has the "y" half chopped off.
* showing an image live / preview does not work when loaded from the service manager. Fine from the media manager. Have not tried to save / reload but guess that is broken.
* blank lines in functions please remove (general)
* questions in comments please removed.
* check_binary why is this outside the class as a standalone function?
* if os.name != u'nt': swap logic round so is positive and less chance of a miss read.
* 320 would this be better to have in the code a file instead of writing to a file each run?
* if self.pdf_program_path.text() != u'': should be if not self.pdf_program_path.text(): - General point.
* setting do not need "given" in the string.
* img should be image (old bad code copied!
* no tests.
* line 53 far too long.
* lines 52-64 do we need all this. if the images are generated then it would be a case of just loading them not processing them again?

Please resubmit due to the age of this request and additionally it will need converting to Python 3 as on 1/9/2013 truck will be converted.

review: Needs Resubmitting

[Tomas Groth (tomasgroth)]

I need some feedback/guidance/help to finish this implementation...
The basic idea is to use mupdf or ghostscript to create a picture for each page in the PDF, and when going to live/preview mode, then replace the service_item with an image-based service_item. I've made it work when going to live/preview from the mediamanager, but I can't figure out how/where to do it from the servicemanager - any hints would be appreciated! As an alternative it can be implemented as the other presentation-backends, with a "player".

I'd also like some directions as to what tests to include? I couldn't find any tests for the other presentation backends...

And finally, I've added some extra fields to the presentation-settings-tab, and for some reason now all fields has moved a bit to the right instead for being to the far left - any hints as to why?
