Python API

Requirements

The Pixet Python API can be used from the Python interpreter integrated in the Pixet program or from commandline with external Python without the Pixet.

For starting from the Pixet Python scripting plugin are not need any special files.

If you want to run scripts without the Pixet, need additional files:
API functions using of pypixet.pyd and pypxproc.pyd and need Python versions 2.7 to 3.x, for Windows the Pixet core dlls: pxcore.dll, pxproc.dll, or linux .so ekvivalents.

The Pixet core need the pixet.ini file with proper hwlibs list inside, necessary hardware dll files (eq minipix.dll), subdirectory “configs” with config files for all present imaging chips (eq MiniPIX-I08- W0060.xml).

For Pixet files details see:

• Small: Pixet SDK: Auxilliary files
• Details: Main directory of the API-using programs, independent on the Pixet

Pixet core on Windows need more Microsoft Visual Studio .NET standard dlls (vccorlib140.dll etc).

Overview

The python API can be used:

• directly in the system console, using a general python interpret
• in the Pixet program integrated python console

The base is pypixet object. It has methods for initialize and deinitialize, can create the pixet object.
The pixet object have device list, can create device objects and allows access to global properties.
A device objects have methods for acquisions and allows access to device parameters.
The pypxproc object is intended for use to processing of a data.
The pygui object allows you to create your own graphical interface. It can be used only if a script is run from the Pixet program.

Small code example for using in the system console or other third-party environment, with the Python 3.7:

import pypixet

print("pixet core init...")
pypixet.start()
pixet=pypixet.pixet
devices = pixet.devicesByType(pixet.PX_DEVTYPE_TPX3)
dev = devices[0]
dev.setOperationMode(pixet.PX_TPX3_OPM_EVENT_ITOT)

print("dev.doSimpleAcquisition (3 frames @ 1 sec) - start")
rc = dev.doSimpleAcquisition(3, 1, pixet.PX_FTYPE_AUTODETECT, "example.png")
print("dev.doSimpleAcquisition - end:", rc, "(0 is OK)")

pixet.exitPixet()  # save settings, correct stop devices and core exit
pypixet.exit()     # both lines mportant if third-party debug environment used

Small code example for using in the Pixet python console with integrated Python:

# do not create the pypixet and pixet, they exist by default

devices = pixet.devicesByType(pixet.PX_DEVTYPE_TPX3)
dev = devices[0]
dev.setOperationMode(pixet.PX_TPX3_OPM_EVENT_ITOT)

print("dev.doSimpleAcquisition (3 frames @ 1 sec) - start")
rc = dev.doSimpleAcquisition(3, 1, pixet.PX_FTYPE_AUTODETECT, "example.png")
print("dev.doSimpleAcquisition - end: %i (0 is OK)" % rc)

# do not execute the pixet.exitPixet(), it will cause whole the Pixet program to exit
