Issue with Visualize command with CGImageRef

[mohamede1945]

Whenever I try the visualize a CGImageRef. I got the following error:

error: error: cannot initialize a parameter of type 'CGImage *' with an lvalue of type 'CGImageRef' (aka 'CGImage *')
error: 1 errors parsing expression
Traceback (most recent call last):

Do you know what image format the underlying CGImageRef uses?

The visualize command is making use of UIImagePNGRepresentation, which the documentation states:

A data object containing the PNG data, or nil if there was a problem generating the data. This function may return nil if the image has no data or if the underlying CGImageRef contains data in an unsupported bitmap format.

You are correct. My data is in JPG format. I'll close it as invalid.

I should look into what it would take to support other formats.
