Cleaning up B&W prints for Wikimedia Commons

[ineuw]

Until now, I was using Irfanview in Windows and with Wine. I no longer want to use a Windows software in Linux, and want to change to using XnView.

I clean up and restore public domain drawings and prints, mostly black & white. The most important tool is the color replacer in 0 to 255 grayscale range. Can anyone point me to where/how the color replacer of XnView? By pointing, I meant in the manual.

This is my homepage on Wikimedia Commons, where my contributions are listed.

The images in this link are the cleaned grayscale work of the yellowed originals.

Until now, I was using Irfanview... I clean up and restore public domain drawings and prints, mostly black & white. The most important tool is the color replacer in 0 to 255 grayscale range.

I moved from Irfanview to XnView when I discovered that it had a 'Levels' adjustment option, my preferred tool when enhancing scans; as far as I know it still isn't supported in the other software unless possibly under a different name. You might therefore, as well as exploring the viewer menus which are now becoming somewhat complicated, take a look at:

Image > Adjust... > Levels... And also possibly: Effect > Effect... > Map -- Saturation

The Levels option is assigned the useful keyboard shortcut 'L'.

I normally convert nominally black-and-white images to grayscale before using Levels, let me know if you know a better method!

Due to the number of interface changes, and also the addition of new options, there is now little up-to-date documentation available.
