Not able to extract English text from black text on a white background

[John Alway]

Hello,

I've been working with Tessearct 4.1.1 (in C#, Visual Studio).   I've been taking screenshots of small regions of my screen to capture text from youtube comments, TikTok chats, etc., and it has done a great job of converting the print in the images to text.   I thought it did a great job on this text.

However, it failed when I took a screenshot of text in my notepad application, which is the simplest text imaginable. A list of words.  It's black text on a white background.  It only extracted a word or two from the document.    The image snapshot is just 190 by 260 pixels.   It says it's 300x300 dpi.    

Here is the text from the document:

Up
Hey
Down
What
Left
Left
So
That's
It
Start
and this
what
Down

Here is the screenshot image I had Tesseract extract from.

Is there a way to fix this problem?

Many thanks for any help.

Regards,

...John
