bqplot-image-gl's Issues

bqplot figure does display in Accordion

Describe the bug
ImageGL mark for a bqplot.Figure does not appear in ipywidgets.Accordion container. You can see it outside of the container, but not inside. I am using the beta version of ipywidgets v8.

To Reproduce
Using the basic example script:

from ipywidgets import *
import numpy as np
from bqplot import Figure, LinearScale, Axis, ColorScale
from bqplot_image_gl import ImageGL
scale_x = LinearScale(min=0, max=1)
scale_y = LinearScale(min=0, max=1)
scales = {'x': scale_x,
          'y': scale_y}
axis_x = Axis(scale=scale_x, label='x')
axis_y = Axis(scale=scale_y, label='y', orientation='vertical')

figure = Figure(scales=scales, axes=[axis_x, axis_y])

scales_image = {'x': scale_x,
                'y': scale_y,
                'image': ColorScale(min=0, max=1)}

image = ImageGL(image=np.random.random((10, 10)), scales=scales_image)

figure.marks = (image,)
figure
Accordion(children=[figure])

Here is my environment:

Angle (theta) support for some shapes

As mentioned in glue-viz/glue-jupyter#396 , in Jdaviz, when one draws a shape like rectangle or ellipse, and then gives it a non-zero angle, when you click on the shape to drag, there is a gray shadow (AFAIK controlled by this package) that does not understand non-zero angle.

As a result, we see a "gray" shadow that isn't rotated as we drag, but when we finalize the selection, the final shape has the desired rotation. This behavior is very confusing.

Desired outcome: bqplot object in JS to also understand angle (theta).

Example file: https://github.com/glue-viz/bqplot-image-gl/blob/main/js/lib/BrushEllipseSelector.js

Profile viewer marks do not appear in Linux VM

Describe the bug

Hi all, had a bit of a weird bug come through our help desk. We had a user trying to use jdaviz on a Linux VM on their Windows machine, and everything worked except for the profile viewer, which failed to display any marks (the image viewer worked fine). They were able to get the app to work properly by turning off use of WebGL and using the non-GL bqplot instead, which we have available as a fallback.

This might belong in bqplot-gl since this repo was initially for images only, but I'm unclear if you've actually migrated to using that repo instead of this one.

Add support for variable opacity

One thing that Matplotlib images support that would be good to add here is support for colormaps that have variable opacity - for instance when showing a density map of points, it can be useful to have a colormap that is all the same shade of e.g. glue but using opacity variations for the intensity - this allows multiple different density maps to be shown at the same time.

We could add this here by adding a new scale opacity that could be set to a LinearScale, then update the JS code and shader so that it takes this into account.

Widget not working correctly with voila

using jupyter notebook basic.ipynb, everything works fine. However, if I do voila basic.ipynb the figure doesn't appear and I get the following errors in the js console:

DOC: ImageGL needs WebGL

From testing #37 , I found that ImageGL does not work (no error message, just nothing shows) on RHEL 7 (has NVidia but the driver is probably very old). Unfortunately, it is a company machine and I am unable to upgrade anything there.

This WebGL requirement should be properly documented.

Allow filtering of events in MouseInteraction

To avoid too much communication between the frontend and Python in MouseInteraction, I wonder if it might make sense to pre-filter what kind of events one is interested in, e.g.:

interact = MouseInteraction(..., events=['click', 'keydown'])

Otherwise when one is not interested in e.g. move events there is unnecessary constant communication.

Issue when installing Jupyter Lab extension

When doing:

jupyter labextension install js

I get the following:

Issues with drag events

I am starting from the mouse.ipynb notebook. If I define the interaction as:

interaction = MouseInteraction(x_scale=scales_image['x'], y_scale=scales_image['y'], move_throttle=70,
                               events=['dragmove'])
figure.interaction = interaction
def on_mouse_msg(interaction, data, buffers):
    print(data)

interaction.on_msg(on_mouse_msg)

then dragmove events don't cause the callback to be called. Instead I need to specify all drag events, i.e.

events = ['dragstart', 'dragmove', 'dragend']

for dragmove events to work. That's the first issue.

The second issue is that if I originally set events=['mousemove'], then hover over the image, triggering the callback, and then set:

interaction.events = ['dragend', 'dragmove', 'dragstart']

the callback is not called. This took me a few hours to reproduce as it requires a very specific sequence of events!

bqplot-gl

cc. @maartenbreddels @kaiayoung @ibdafna @SylvainCorlay

It has been discussed at the bqplot board to remove ThreeJS as a dependency and make an official bqplot-gl repository.

This allows not depending on ThreeJS if not needed, and making bqplot more modular.

The new bqplot-gl has been created under the official bqplot organization: https://github.com/bqplot/bqplot-gl.

It would be awesome if all GL marks from glue-viz/bqplot-image-gl could be moved upstream. It would make them more official to the bqplot project. I already moved the LinesGL mark and can move the ImageGL as well.

Add tests and set up continuous integration

We should include some simple tests to make sure everything works fine, and set up Travis to run the continuous integration.

Try to implement "generic astro image API" with ipyastroimage

As part of some work trying to build a python-friendly API for image viewers, I built this "concept" document:
https://gist.github.com/eteq/bb625148969db51b2b03b71e92ca5231

It would be an interesting experiment to see if this image viewer can meet that API. The target case I had in mind with this was indeed notebooks, so this might be a perfect simple test case for it...?

How to stack MouseInteraction with other interactions?

I tried this but it doesn't work. I must have misunderstood how they supposed to stack. My goal is for the following to happen:

When mouse is moving, it updates cursor info (this part works).
When I scroll, it either pans or zooms (I want to control this part in a finer detail, but for now, if either one would work, that's great)

Code that does not work:

image = figure.marks[0]  # figure is some bqplot-image-gl object

# This part is taken from example in #37
interaction = MouseInteraction(
    x_scale=image.scales['x'], y_scale=image.scales['y'],
    move_throttle=70)
figure.interaction = interaction
interaction.on_msg(some_callback_function)

# My feeble attempt to stack pan/zoom onto it
from bqplot.interacts import panzoom
interaction.observe(panzoom(figure.marks))

ImageGLView.data is a Float64Array which WebGL does not support

Loading an astronomical image into Imviz in Jdaviz triggers this, as noticed by @rosteen . Not sure where the fix should be.

bqplot-image-gl/js/lib/imagegl.js

Lines 286 to 289 in bd7bac1

               console.warn('ImageGLView.data is a Float64Array which WebGL does not support, will convert to a Float32Array (consider sending float32 data for better performance).'); 
        
               data = Float32Array.from(data);

Image widget not showing.

Hi I was trying to show image with Ipyastroimage with input being numpy array
Input:
color_scale = bqplot.ColorScale() scale_x = bqplot.LinearScale() scale_y = bqplot.LinearScale() image = AstroImage(image=data, scales={'image': color_scale, 'x': scale_x, 'y': scale_y})

Output:
AstroImage(image=array([[ 4.1139283, 4.4903197, 4.6050134, ..., 5.6953917, 9.383944 , 10.25792 ], [ 4.670872 , 5.606509 , 5.4989924, ..., 3.6070461, 5.371789 , 6.604827 ], [ 4.3647394, 5.54057 , 6.055377 , ..., 3.5973377, 4.83896 , 6.737476 ], ..., [22.368206 , 11.044641 , 4.1607943, ..., 3.3912497, 4.3756213, 3.659427 ], [ 9.733774 , 6.5522428, 3.4279304, ..., 2.7059777, 2.4026213, 2.7714913], [ 4.641999 , 3.700842 , 3.0346284, ..., 3.0442555, 2.8392305, 3.0797014]], dtype=float32), interactions={'hover': 'tooltip'}, scales={'image': ColorScale(), 'x': LinearScale(), 'y': LinearScale()}, scales_metadata={'x': {'orientation': 'horizontal', 'dimension': 'x'}, 'y': {'orientation': 'vertical', 'dimension': 'y'}, 'image': {'dimension': 'color'}}, tooltip_style={'opacity': 0.9})

As you can see only AstroImage follow by arguments value is shown

Then I try to put it in bqplot figure by using following:
fig = bqp.Figure(marks=[image])
display(fig)

still it didn't shown anything.

If you have any idea what might the problem, please let me know.

Thanks!

bqplot-image-gl fails to build from source

It was working before but now it is failing. Definitely not because of something you did here, because the last commit was from Aug 2022. So it is something you did not do, i.e., upstream changed and is no longer compatible.

Blending issue with multiple ImageGLs

The following notebook demonstrates a bug in the blending of multiple ImageGL marks:

https://gist.github.com/astrofrog/08735bc30c2f8980edeaae0fd0842352

In short, I set up two arrays that look like:

image1 = np.array([[[255, 0, 0, 255], [0, 0, 255, 255]], [[255, 0, 0, 0], [0, 0, 255, 0]]]).astype(np.float32)
image2 = np.array([[[0, 0, 255, 0], [255, 0, 0, 0]], [[0, 0, 255, 255], [255, 0, 0, 255]]]).astype(np.float32)

In both cases the top and bottom row of pixels is the same within the image except that the top row (in the first case) and the bottom row (in the second case) are transparent. If I show the arrays individually I get sensible results:

But if I show the two at the same time the result looks incorrect:

It seems perhaps the alpha compositing is not correctly taking the opacity layer into account. I haven't had a chance to dig into the shader code yet.

	} else if(data instanceof Float64Array) {
	console.warn('ImageGLView.data is a Float64Array which WebGL does not support, will convert to a Float32Array (consider sending float32 data for better performance).');
	data = Float32Array.from(data);
	type = THREE.FloatType;
