CPImage and Basic Auth

[Todd Freese]

I create an CPImage using initWithContentsOfFile and pass it a URL to a static image.

Now, I need to get an CPImage from a server that requires HTTP Basic Auth. How do I do this? Is there a way to set HTTP header fields for the call to get the image in CPImage?

So I understand how to do basic auth.

My question is in a call like this:

proxy = [[CPImage alloc] initWithContentsOfFile:@"https://server.foobar.com/myImage"];

How do I add the http headers? Is there a way to access the underlying CPURLRequest that CPImage is using?

Make a CPURLRequest yourself to get the data with the correct header, then use `CPImage -initWithData` to create the image.

Almost there...

Is there a way to get CPData from the CPURLConnection? Or do I just make a CPData from the string return?

This is what I have so far:

- (void)connection:(CPJSONConnection)aConnection didReceiveData:(CPString)data

{

    var returnCode = [aConnection _HTTPRequest].status();

    if (returnCode == 200) {

        var imageData = [[CPData alloc] initWithRawString:data];

proxy = [[CPImage alloc] initWithData:imageData];

        CPLog(proxy)

     }

}

My log statement returns:

<CPImage 0x008d3b> {

   filename: "data:image/png;base64,///9/QAQSk...RK//03///9",

   size: { width:-1, height:-1 }

}

That isn't working?

[Todd Freese]

No, it seems to be making an image with a size of -1, -1.

But if I call setSize on it, I see an image. But I don't know the correct sizes of the images.

Todd

[Aparajita]

That's normal, the size isn't set until the next pass through the event loop. You can either subscribe to the CPImageDidLoadNotification on the image, or set a delegate and implement -imageDidLoad:(CPImage)image. In either of those handlers use [image size] to get the size.

[Todd Freese]

I was wrong about it working when setting the size.

Do I need to tell CPImage what type of image it is? Or is that in the data?

It should be in the data.
