windows - How can I draw a line in a printer that looks thinner than a pixel? -

-

i know gdi limitation. gdi can draw line width @ least 1 pixel. still want draw line looks thinner 1 pixel in printer.

do mean can this:

with clogbrush begin     lbstyle := bs_solid;     lbcolor := acanvas.pen.color;     lbhatch := 0; end;   dwstyle := ps_cosmetic or ps_alternate; acanvas.pen.handle := extcreatepen(dwstyle, 1, clogbrush, 0, nil); acanvas.moveto(x1, y1); acanvas.lineto(x2, y2);

you (for example) draw line of alternating black , white pixels. @ least typical laser printer @ 600 1200 dpi, blend pretty line looks less dark. should add, however, line 1 pixel wide laser printer pretty thin.

a lot here depend on printer though. example, ink jet printers, thinnest line can draw thicker, when/if quote same (or higher) resolution. lines aren't quite clean either -- in both cases, they're darkest @ center, , fade paper color, ink jet "fade" quite bit slower edges of line aren't clean.
