In my previous post about the “Save to disk” action I meant to show you how you can edit actions but it completely slipped my mind. On the Actions tab you can simply double click an action to open its editor. Alternatively you can right click an action or output for more options.
The “Copy to clipboard” action also received a nice upgrade. In previous versions the action simply copied the image to the clipboard using the universally supported bitmap format. Unfortunately this format doesn’t support 32 bpp images so you end up losing the alpha channel. If you want to paste an image that retains the alpha channel and the application you’re pasting it into supports it then you can select “Copy as PNG image” instead.
Here is an example of a screenshot produced by the “Copy to clipboard” action that I then pasted into OneNote. If you look carefully you should be able to see the OneNote grid lines even through the window frame in the image.

FYI, there is such a thing as a 32 bpp ARGB bitmap, it is not supported by all apps, but it is used by such things as XP Visual Styles, Vista menu images, ribbon control etc
I am aware that the bitmap format is capable of 32bpp – I use it myself quite frequently. I have however never found an application that supports it as a clipboard format so there’s no point in using it for that. All the apps that I’ve tested assume its 24bpp or less.
Still, 32 bpp BMP can be used for ‘Save to disk’ option. There is plenty tools (for ex. Imagine, also is a plugin for Total Commander), which can open and convert them. Though I can totally agree with you on that there’s no point to use it in WC – whoever wants a 32bpp bitmap, can easily get it from PNG in one click.
Exactly. If you need 32bpp that’s not a problem and you can choose either the “Copy to clipboard” or “Save to disk” actions and you can pick from a variety of 32bpp image formats.
