Yeah, need to adapt to changes made in SupportExt since interact in TextOFX now crashes.

Will fix when I get time tomorrow.

Requested by William Young.

Support WYSIWYG.

TextFX as-is works, but I always wanted it to be a real WYSIWYG editor. This actually don't require too much work on the plugin side, but will however require some changes in Natron, I need to implement kOfxParamStringIsRichTextFormat.

I have the Widget editor more or less done, so it shouldn't be that hard. Will try to get this working by the end of next month (-ish).

Note to self so I don't forget :)

Also note that I have started a new text project at https://github.com/rodlie/openfx-text (wip).

I have installed all of the dependencies by looking at the travis file (line 33). I ran this command make -DCMAKE_INSTALL_PREFIX=/usr/OFX/Plugins .. and go this output:

CMake Warning (dev) at /usr/share/cmake-3.13/Modules/FindOpenGL.cmake:270 (message):
  Policy CMP0072 is not set: FindOpenGL prefers GLVND by default when

  FindOpenGL found both a legacy GL library:

I can't find which package lodepng is in. Also, this laptop uses intel drivers as it doesn't have a dedicated gpu. Does this usually present compilation issues?

I recently was looking to try out Natron. I run Arch Linux and simply was able to go through the AUR to obtain the natron package. I run into an error when compiling openfx-arena.

I've checked that I have all the required dependencies and was curious if there is something I'm missing or if there is an issue. Here is my output of making the file after git cloning it. Many thanks for reviewing this! (apologies on the formatting)

I don't usually make requests for new features but I've stumbled upon a few areas where I think the tile node could be improved. Hopefully these suggestions aren't too far beyond the scope of work being done! I don't think any of these additions would interfere with the tile node's current default operation.

Reformatting

Currently the tile node takes the source input and tiles it while maintaining the source input format. This results in a loss of quality of the image as it gets tiled according to how many rows and columns the user has set.

While this currently works as expected the end result isn't always desirable. An option to tile the source while maintaining its original resolution and increasing the output format size accordingly would be quite nice.

Offsets

Currently the tile node does not have an option to offset the tiling. This would be nice to have for both the rows and columns.

Additional tile patterns?

This is possibly beyond the scope of the tile node but implementing different shapes such as hexagonal or triangular tiling (by cropping the edges of the source input) or Histogram-preserving hex-tiling (PDF) could be neat?

Make sure to follow our issue report guidelines

• I'm using the latest version of Natron (not required but recommended)
• I've restarted Natron and the issue persists
• I've run Natron via the command line and the issue persists
• I've followed the contributing guidelines to the best of my understanding
• My issue is not on the issue tracker or in a pull request already (go search for it and dig around a little bit!)
• This bug is reproducible

What were you trying to do?

I am trying to read a subtitle (.srt) file into the Text node. The contents of the file are:

1
00:00:00,000 --> 00:00:01,500
First item in a list

2
00:00:01,600 --> 00:00:03,100
2. Second item

3
00:00:03,200 --> 00:00:04,700
Third item

example_subtitle.zip

What did you expect to happen? What happened instead?

The file can be read and played back, however the second subtitle doesn't display.

I suspect this is because the second subtitle starts with a number

Step-by-step reproduction instructions

1. Start Natron
2. Add a Text node
3. Load the above .srt file

https://discuss.pixls.us/t/line-spacing-in-natron-text-node/25984/2

I made some OpenCL (1.2) plugins while at Inria and if I remember right they worked quite well. They where never bundled with Natron since they require OpenCL and we can't provide OpenCL with the bundle (must be provided by the system or graphics driver).

The plugins consist of just some random effects and a meta node that can be used to develop OpenCL kernels and use as a base for PyPlugins. It should also be easy to add new plugins.

We should possible consider splitting them out as openfx-opencl and let travis provide binaries for people to use. Or make travis build binaries in this repo (I can get travis to also build mingw binaries).

I will of course first go through the plugins and code.

Also, ImageMagick is able to probe for libOpenCL before loading it, I should check what they do.

@rodlie do you have an idea of what's happening?
I see that in every Linux build (using the docker images)

it gives a black image on linux and macOS
It was working OK in Natron 2.2.9

It should use .reset():

            globalParams.reset(new GlobalParams(popplerData.c_str()));

I have to ask.

Hi, I think AudioCurve would be a very powerful node if I could select (with parameters) a frequency and a decibel (for that frequency) to act on to insert a keyframe. Thus, it will be possible to animate each character on a specific frequency. I implemented something similar in browser JavaScript and was about to adapt it to Affter Effects. But here it is almost finished. I have been able to see the part of the code where the audio file is read. But I haven't accomplished much else, maybe with some help and documentation I could. Thank you.
