Note the final image where you say 'NO' in your comment works with the addition of a Trigger delay (sorry I missed that).
This will ensure the loaded image is pushed into the Freeze, and that any updated Picture is also updated.
This method with the freeze is what I have been using for years (we didn't have GLSL at that time), I don't know if there is any performance benefit?
It does seem the default GLSL is the easiest approach :)

I'm on Isa 2

Unfortunatley the Matte actors in Isadora 2 have a bug related to the 'scale fg' function, that makes it so I can't port this User Actor backwards to Isadora 2.
Here are the guts of the user actor in case its useful for anyone else to understand.

The basics are that the image is placed onto (using Matte++) a Square canvas (using the greater of Width or Height).
Then the square canvas is rotated 90, 180, 270 degrees (as needed). Finally the Square canvas is cropped back down to the image size.

Thanks @bonemap for pointing that out, and thanks to the wonderful @gunther for making such a helpful tool <3

I've seen it on the plugin page and I've been meaning to try it out myself for some time now. Maybe today is finally the day :)

Best wishes,

@Woland will keep me informed about this. If we can find a way to reproduce the problem, I will fix it as soon as I'm able.

Best Wishes,

You said: I'd like to play a series of individual pictures in a fast-cut sequence up to 10 pictures per second or more

This is certainly do-able, but I think my workflow would be to make them into a movie file and play that if I was having trouble getting it to work programatically.

You said: Ideally with no tearing appearing across the screen between pictures

This is a function of the refresh rate of your display and how well it synchs up with the rate at which you are flashing images across it. With your setup, it's going to be like you're playing a 10 FPS movie, which may or may not look good with the display you're using depending on whether the refresh rate of the display meshes well with your 10fps content.

You said: each picture as large and crisp as possible

"Crispness" is a function of your media's resolution and your output display's resolution. If your image or display have a low pixel count, the image will not be "crisp".

You said: is the following patch the best way to do this 

Use a Pulse Generator set to 0.1Hz instead of a Wave Generator, (the wave gen will trigger constantly and make your images cycle much faster than 10fps), but yeah, other than I'd give that patch a go. 

Make sure to initialize the Picture Player "picture" input at 1 (So it starts at the beginning). 

Make sure to initialize the Counter "cur value" input at 10 (to ensure that you can see your first image for 1/10th of a second before it switches to the second image).

You said: any recommendations on what image format is best to use?

Make sure that the resolution of your images all match, and that this resolution is the same resolution as the display to which you are outputting.

.jpeg if you don't need an alpha channel, .png if you need an alpha channel.
