Figure 29: wxPropView - Selecting a camera description
Now, when a camera is connected, that differs in one or more parameters from the default offered by one of the
available base classes and no special description for the imaging device in question is available a new matching
description must be generated.
Note
It's also possible to modify one of the standard descriptions to adapt the parameter set to the used imaging
device, but this method is not recommend as this would define something to be
"standard" , which in fact is
not. Therefore it is not possible to store the standard descriptions permanently. It is, however, possible to
modify and work with the changed parameters, but these changes will be lost once the device is closed.
The recommended way of adapting an imaging source to a capture device is to create a new description for a imag-
ing device that does not completely fall into one of the offered standard descriptions. The first thing to decide when
creating a new camera description is to which existing description offers the closest match for the new description.
Once this has been decided a copy of this description can be created with an arbitrary name (that must be unique
within the family the description is created from). Under
wxPropView (p. 48) this can be achieved by
• typing the new name in the parameter edit control right of the "Copy" method of the camera description to
create the copy from.
• Afterwards, press ENTER to commit the new name and then the "Copy" method can be invoked
• by right clicking on the name of the function and
