Changing colour gradients

A reoccurring issue, is to change the a colour in an image to another, but retaining the color gradient. For example, changing a greyscale image to green, but the light greys change to light green, the dark grays to dark green. The image is greyscale because the black drawing is anti-aliased with varying shades of grey.

Corel Paintshop Pro includes the Color Replacer, which is supposed to do just this. Either I do not understand how it works, or it does not quite do what I was expecting, and it ignores the lightest pixels, or changes all pixels to the same shade of colour.

The solution is to the use the Red/Green/Blue color affect. For black text on a white background, the trick is to invert the image first, to white on back. Then use the Red/Green/Blue color affect.

There must be an easier way!

Acrobat Reader installs in Ukrainian (Russian)

Having installed Adobe Acrobat Reader, I found it had installed something called Adobe Acrobat Reader DC, with all the menus in Ukrainian, which looks like Russian, with Cyrillic characters.

I also found that when I tried to update this version, I would get a message: “newer version already installed”. The solution….

How to run Eudora v7 on Windows 10

See also: Aid4Mail (Migration)

I still run Eudora v7.1.0.9, currently on Windows 7 (32-bit), and now need to move everything to 64-bit Windows 10.

It is not straightforward, because you can’t run Eudora from the 64-bit /Program Files/ directory, and you certainly can’t store your emails there, because the directory is write protected.

Moving to Windows 10 32-bit /Program Files (x86)/ might appear to be a workaround, but you can’t move your Eudora installation to another directory, because all the directory paths would change, in particular, the directory to attachments.

One of the error messages I was getting was “Cannot start Eudora the first time with attachments”

Here’s how I solved the problem…
