ids-peak 1.10.0.0.3

ids_peak - A library for device communication

ids_peak provides python bindings for the IDS peak genericAPI. It exposes all the functionality of the peak genericAPI and requires at least the drivers and GenICam transport layers to be installed, which are included in the IDS peak SDK.

Benefit from many Python advantages, for example the interactive programming of your IDS camera. Write and test small code snippets without the complex setup of a programming IDE including a toolchain. This package is ideal for prototyping IDS camera applications for all supported peak genericAPI platforms (Windows, Linux, Linux Embedded).

Installation

$ pip install ids_peak

Quickstart

This example shows how to open a device, start image acquisition and how to convert a buffer to an ids_peak_ipl.Image.

NOTE: For the sake of simplicity, most of the error checking has been omitted in this example.
