Hi Andy, Why? There are toons of libraries, utilities and whatever over there. It have to be easy to realise, because it is .NET, very well known to Dyalog APL. thanks, sasha.

Dear Woody, I wanted to use my reply to you to get out doc file to test Vinset's advice. I didn't find anything attached. That stupid I am:-( Sorry. After more play with the topic, I think you were (and you ARE) right! When I open old documents 1) on windows and 2) with ms word, everything goes ...

Hi Vince, You helped me as 1,000 times before. I didn't know about this option (this font). Thanks a lot! Have you heard about automation of font conversion in doc(x) document?

Can you please upload an example of the ...

I sent some "code" here& what is opinion now? thanks. /sasha Hard to say without seeing your code, but my guess is that if you are creating 24-bit images but only write values in the range 0-255, then you effectively only use the blue channel. You'd need to encode it using all 3 channels to get gray ...

Hi Ray, Thank you for your respond and very nice to contact you again! Your answer sounds a bit depressing... About 8x8 arrays... Do you see my post, that the problem is resolved easily?
