objectStreaming Images
- Parameters
- data_callbackcallable
The function to call for data updates
- image_keystring, optional
The key for the image data in the callback result. If a key value is not set, but there is only one key in the data, the data at that key will be used.
- stepsint, optional
The maximum number of steps to iterate
- intervalint, optional
The length of each step in milliseconds
- sizestring or int or tuple, optional
- The size of the displayed image. It can take the following values:
‘contain’ - to indicate that the image should be scaled to fit inside the plot area
‘cover’ - to indicate that the image should scale to cover the entire plot area
int - to indicate a square with a pixel width of height of the given integer
(int, int) - to indicate width and height values in pixels
- plot_widthint, optional
The width of the plot in pixels
- plot_heightint, optional
The height of the plot in pixels
- annotationsWindow, optional
Window containing image highlighting information
- transformersfunction or list-of-functions, optional
Functions to apply to each image prior to displaying
- Returns
- Attributes
- data_callbackcallable
The function to call for data updates
- intervalint, optional
The length of each step in milliseconds
- stepsint, optional
The maximum number of steps to iterate
