Cool effect, thanks for your sharing, ALKOON :)

values of points (i.e. Pixel xy-Coordinates) retrieved by PixPoints(), are exactly between [(0, 0), (width - 1, height - 1)]
here width and height construct the minimal box that holds the text





It seems that the cut does going through the middle of every text.

TCAX using FreeType library as its built-in font engine (to retrive metrics, pixels, etc.)

some links that I thought may be helpful

Thank you milky =D
but don't you think it's too much that I have to read ? XD
anyway it's helpful, I ...

:) Yes, I think so. But I cannot figure out exactly what problem are you facing, so, I give it back to you.

I wonder whether it's convenient for you to draw a simple graph to show your idea about how the pixels (particles from text) should move?

round(PIX_ori[1][1])
It's better than
_Height[_i][_j]

_Height[_i][_j] should be equal with the original PIX[1][1] (PIX_t), since 'PIX' has the structure ((initX, initY), (width, height),...), but 'PIX' may be manipulated, applied with filters, transformations, etc. some of them will enlarge or reduce PIX, such as PixBlur (enlarges a bit), so in this case _Height[_i][_j] will be smaller than PIX[1][1] (what's more, after combination with PIX generated from FontOut font, PIX will be even larger, _Height[_i][_j] should be with the same metric as PIXs directly generated from Font)

so, as a conclusion,
the solution provided by saiyaku is better.

but still cannot figure why not cut exactly through every middle of texts,
I suggest you using tcaxLog() --- to dump information into log files, or simply use Python built-in print(),
and with the help of Pause() function, to do some debug.
