[Hide transparent parts in images while editing]

1. When you save out the file after you've erased the background, save it with PNG.  The other filetypes don't support partial transparency.

2. Sorry, but the help file isn't currently available for download.  It's available online at http://www.getpaint.net/doc/latest/ .

Thank you, david.atwell, for the tip;  - it really works!

[Hide transparent parts in images while editing]

Hello.

I also, probably, have such a problem. 

I have a video, where at some point I would like to see an image, appearing in the middle of the right side of the screen. 

Figuratively speaking, I should like to cut (like with scissors) the image along its contour and move it in its purest form onto  the clip. 

My attempts are futile: 

On the screen during playback there arose a rectangle, completely covering a portion of the clip, 

and the image located inside the rectangle with a some background.

I would like to know as well, how to position the image at a desired location on the screen, and how to change the geometrical size of a image (but, maybe, such things need to be done only with a Video Editor but not with the Paint.NET ?)

In addition, how can I download the help file (manual) from the site Paint.NET?
