No, it is not a bug. It might help to think of the layer as a pane of glass you're swapping between window frames. You take the transparency with you when you replace the old glass with new (in PDN you're copying the clear bits as well as the opaque pixels in the layer). If you were to double-glaze within the new frame, you add the second pane of glass to the first, preserving both layers of transparency (this is akin to pasting into a new layer). This might help explain: https://www.getpaint.net/doc/latest/WorkingWithLayers.html

The trick here is to work on only one half and ignore the other. When you're done, mirror the completed side over the other.

Difficult because the writing is so faint and the blue pen is doing a great job of obscuring it (as, I suspect, the person scribbling on it intended). I'd try to read the letters and reconstruct the words from that rather then trying to restore. J-e-t-o-e-i | ?-?-d-e? Do you have more writing to compare?

Assuming your text is over a uniform background..... Select the background with Magic Wand and the Shift key held down (this selects all of the background including the bits inside closed characters) Invert the selection with Ctrl+ I

You've removed the background surrounding color, leaving blank pixels. To show you where this transparency is, paint.net shows you the checkerboard pattern. The checkerboard pattern is not part of the image, it is there as a visual cue to you. You've saved as a *.png (which support transparency). Correct This is a result of incomplete removal of the white background. It shows up at the edges when you place another color behind the image. The usual method of removing these artifacts from the edges is to run the AA's Assistant plugin over the layer.

It stops spammers and bots polluting the forum.

No plugin is going to do that. I'm seeing a trend in your posts where you ask for plugins to do artistic work for you. How about learning some fundamentals and applying that to create art? Stained glass tutorial:

Long shot: Try replacing the spaces in the directory with underscores? \Analog_Efex_Pro_2\

No it doesn't. Copying does not change the current layer, so there is no change (or addition) to the History. Correct (you can change the Primary & Secondary colors & View conditions for e.g.). Actions which change the active layer remove later items in the History. This is like the Grandfather Paradox of time travel, where travelling back in time and making changes alters the current reality.

Or.... 1. Create a new layer (Ctrl + Shift + N). By default the layer should be activated, if not - switch to it 2. Use O to activate the Line/Curve tool ("o", not zero) 3. Draw your line/shape 4. Duplicate the layer as many times as you need (Ctrl + Shift + D)

I'll repost the workaround from that ^ thread:

JPGs do not support transparency. You will need to save it in another format, like PNG. This is likely the result of non-uniformity in the black background. The fix is to identify the shadow area and fill it with the same black shade as the rest of the background. How? Use the magic wand on the background and slowly increase the Tolerance until all of the background is selected. Edge Detect didn't mess up - it correctly processed the image. The fault here is that the plain black background isn't as uniform as it appears to the naked eye.

How do you want to animate the image? PNG or WebP are alternative options.

I don't recall a plugin that can do that. Maybe G'MIC has a filter or someone has an idea of a convolution kernel which might do what you're asking. See: https://legacy.imagemagick.org/Usage/morphology/#kernel (search within the document for skeleton)

January Update A single new plugin this month. It's a piece of GPU magic from paint.net Dev Rick Brewster! Median Sketch (GPU) Rick Brewster GPU-based approximation of the Median effect. Think of this algorithm as taking a Monte Carlo approach to calculating a median. To improve performance, all pixels are not rendered at full fidelity, only some are rendered and the rest are guessed/interpolated/extrapolated. Source code provided.

The best way to do this is to create a new layer and redraw the object.

How about a Reset All for the utility windows? Perhaps under Settings > UI?

When creating the image, use a new layer for each different type of element. ONLY put that type of element on the layer e.g. grid goes on it's own layer. The image above took a few minutes to assemble this way. Mercy! You're doing it hard Activate the Grid layer. Activate the Magic Wand tool Hold down Ctrl & click in as many cells as you want to color. This selects only the cells you click in. Click on the Black Blocks layer to Highlight it Press Backspace (not delete) to fill the selected regions with the primary color (default to black). Want a different set of black blocks? Activate the Black block layer Ctrl + A Delete repeat steps 2-5 from above

It's because Cut puts an entry into the History and Copy does not. Think about it: Cut removes a part of the image - there needs to be a way on undoing this operation. Copy does not change the image, so there is no History entry. Cut & Paste = 2 operations which affect image, so Undo twice to revert. Copy & Paste = one operation (Paste) which affects the image, so one Undo to revert. Clear?

Start with a copy of the original image (never edit the original - always work on a copy ) Activate the color picker and sample the image near the overexposed area. Lower the opacity of this color to less than 60. Add a new layer. With a largish (lower the hardness) brush paint over the overexposed area. Darken the shade you're using (colors window increase the V slider 20%) Increase the opacity of the color to around 50% Make the brush tip 50% smaller Overpaint the area you just covered using two or three three almost vertical stokes with spacing in between strokes. Blur the layer with Effects > Blur > Bokeh (I used radius 19 the others at defaults). I stopped at this stage, but you could add more texture with smaller darker shades (repeating steps 6-9) and a few freckles.

By now you'll have learned to put your image elements on different layers. If you have done this, changing the color of one set of elements would be as simple as activating the layer and using the Paint Bucket tool with the new color.
