making black lines stay black when image is shrunk

[lklauder]

When an image is shrunk (e.g., 20%) lines that were black and sharp wind up with grey borders. Has there been any work on an option to get PDN to guess a suitable reduced line width that can keep horizontal and vertical straight lines all black?

Try switching the quality from smooth to pixilated.

Assuming the reference is to Effects // Distort // Pixilate, I tried that, but it made things worse rather than better.

My current work-around is to use Adjustments // Brightness / Contrast to change the border compromise pixels from grey to black.

depending on the image and the line. sometimes I use BoltBait transparency plugin and up the opacity after I shrink it downsize.

this could possibly also work in your situation also. its worth a try.

You're problem is caused by the way your image is resized, PDN takes averages of surrounding pixels and uses them to construct your down sized images, so when you have black and white the average is grey.

You could try changing the resample option.

The "Smooth/Pixelate" CommanderSozo refers to is a "Quality" toolbar option

available when using the Move Selected Pixels tool to resize a selection.

Suggestion by Boude to "try changing the resample option" of the Image // Resize dialog seems to provide the effect I was hoping for. I found that the bilinear and nearest-neighbor options both kept the horizontal and vertical straight lines pure black and of correct width and left the curved outlines that had intentionally fuzzy edges slightly less fuzzy but not by enough to disturb the desired effect.
