Method Details

init(self, width, height, depth=3, title='Camera View', parent=None, visible=1)
(Constructor)

To specify the resolution of a particular camera, overload this
constructor with one that initalizes the dimensions itself

Overrides:: pyrobot.vision.PyrobotImage.__init__

addFilter(self, func, *args)

Add a filter to the filter list.
Example: self.robot.camera[0].addFilter( "superColor", 3)

getDeviceData(self)

Returns the device data, whatever it might be.

Overrides:: pyrobot.robot.device.Device.getDeviceData (inherited documentation)

getDeviceState(self)

Returns the .state.

Overrides:: pyrobot.robot.device.Device.getDeviceState (inherited documentation)

makeMenu(self, bar, name, commands)

Assumes self.menuButtons exists

makeWindow(self)

Method to make and show the device window.

Overrides:: pyrobot.robot.device.Device.makeWindow (inherited documentation)

saveAsTGA(self, path='~/V4LGrab.tga')

Save a copy of the image to disk, in TGA format (Gimp and display
can read it).

path is the name of the save file, and defaults to '~/V4LGrab.tga'

setFilterList(self, filterList)

Filters take the form: ("name", (args))
Example: cam.setFilterList([("superColor",1,-1,-1,0),("meanBlur",3)])

setTitle(self, title)

Sets the title of the device.

Overrides:: pyrobot.robot.device.Device.setTitle (inherited documentation)

startDevice(self)

Starts the device (sets the .state).

Overrides:: pyrobot.robot.device.Device.startDevice (inherited documentation)

stopDevice(self)

Stops the device (sets the .state).

Overrides:: pyrobot.robot.device.Device.stopDevice (inherited documentation)

update(self)

Update method for getting next sequence from a video camera.

updateDevice(self)

Method called to update the device properties.

Overrides:: pyrobot.robot.device.Device.updateDevice (inherited documentation)

updateWindow(self)

Method to update the device window.

Overrides:: pyrobot.robot.device.Device.updateWindow (inherited documentation)
