    Push the "Save To File Select "JavaScript Icon for Acrobat". If you would like to create an alpha channel mask for this icon select the "Use Mask" option. Use this dialog to select colors off the image to create a mask.

    Use the tool to add colors to the mask and the tool to remove previously selected colors. If there is some variation in the colors you want to use for the mask, use the "Fuzziness" control to include these pixels.

    However, it is best to use images with solid colors to avoid a choppy looking mask. Results: The file you just created has three basic parts. The function that feeds this data to Acrobat, named "ReadIconData". This function works well but is not the most efficient and you may want to play around with it. If you create more than one icon you will need to rename all the variables and functions to reduce name crashes.

    Since this is all happening at the folder level, you will need to do the renaming even if the icons are used in different files.

It has a number of advantages, and what is really nice about it is that browsers have recently added the ability to consume a fetch response as a readable stream. The Body mixin now includes the body property, which is a simple getter exposing the body contents as a readable stream. This mixin is implemented by both the Request and Response interfaces, so it is available on both, although consuming the stream of a response body is perhaps a bit more obvious.

    This is done using the ReadableStream. Also note that the previous example can be reduced by one step, as response. This reads one chunk out of the stream, which you can then do anything you like with. For example, our Simple stream pump example goes on to enqueue each chunk in a new, custom ReadableStream we will find more about this in the next section , then create a new Response out of it, consume it as a Blob , create an object URL out of that blob using URL.

    If the stream becomes errored, the promise will be rejected with the relevant error. Next, we check whether done is true. If so, there are no more chunks to read the value is undefined so we return out of the function and close the custom stream with ReadableStreamDefaultController.

    If there is no more stream to read, you return out of the function. If there is more stream to read, you process the current chunk then run the function again. You keep running the function recursively until there is no more stream to read, in which case step 2 is followed. How do we create this?

    The ReadableStream constructor.
