[pygame] progress on camera module

[el lauwer <el.lauwer@xxxxxxxxx>]

Hoi,

Nirav Patel asked me to post the info on my blog on this mailing list,  
so here is for those that who are interested:

The past two weeks I was busy studying for my examinations, so I  
didn't have much time to work on my GSOC project.
However I was able to do a lot of work to get the __PyCameraObject  
struct__ integrated in the existing code and implemented some  
additional functions.

Here is the definition of this struct, it isn't completed yet because  
some types I would like to put into it cause compile errors.

**PyCameraObject:**

    typedef struct {
        PyObject_HEAD
        char* device_name;              // unieke name of the device
        SeqGrabComponent component;     // A type used by the  
Sequence Grabber API
        SGChannel channel;              // Channel of the Sequence  
Grabber
        GWorldPtr gWorld;               // Pointer to the struct that  
holds the data of the captured image
        Rect boundsRect;                // bounds of the image frame
    } PyCameraObject;

In addition of implementing the __PyCameraObject struct__, I have  
writen the folowing functions.

* **mac_device_init():**
This function initializes the sequence grabber component and prepares  
it for capturing images.
* **mac_device_close():**
I have extended this function so it works with the __PyCameraObject  
struct__.
* **mac_start_capturing():**
At this moment this function
* **camera_start():**
This function just calls the above functions.
* **camera_get_size():**
Simple function that returns the size of the image frame.

###Schedule for this week
This week I am planning to finish the __mac_start_capturing__ function  
so that I can capture images from my camera an put then in a  
SDL_Surface object.
