Thanks, Daydreamer. Arrayplot is Gdi, actually. Speedwise, check the Sinus plot template (attached). Re GET & PUT: There are ways to do something similar in MasmBasic, but I doubt that LordAdef is using them.
if its gdi draw chinese characters,please check in my thread if you can show a smoother solution to this problem Jochen

The text is not the problem, Gdi draws fonts OK. It is the ragged line. Below an excerpt from the plot where I added a line drawn with Gdi+, using high quality anti-aliasing. It does make a difference, but the extra quality is not overwhelming.

You must zoom in quite a lot to see a difference. On Chrome/SlimJet it's holding Control and pushing the mousewheel forward.

Btw this is line width 3; for finer lines, the difference between plain Gdi and high quality anti-aliased Gdi+ is almost negligible. On the right side of the graph, I added a comparison between 5px and 1px lines. If you zoom to 200 or 250%, the difference becomes evident. Note also how neat the Chinese text looks - it's really fine.

maybe d3d can antialias better and faster with full antialias settings

Hi,

I take my words back  :biggrin: It looks like its just impossible to make normal smoothing with GDI, other technologies have to deal with it.

Below, I gave examples showing the difference between display technologies.

maybe - post a demo ;-)
docs says it doesnt antialias lines,only polys in fullscene antialias

Hi jj2007,

I also have no success in the visual studio 2019, I will try on another machine. The first example shows that in GDI it is not reachable, and the second example shows how ideally it should be, taking into account that another mechanism is used. The speed and processing of both techniques are completely different. I do not think it's worth puzzling over this problem  :rolleyes:

you use GDI background color=bitmap? or use background color=null?
for example want to have a moving object,just redraw it together with erase few pixels behind it?

I found this direct2d vs GDI,look below at the images direct2d is smoother curves

The curves are Gdi vs D2D, not Gdi+. They write "When rendering in software, applications that use Direct2D experience substantially better rendering performance than with GDI+ and with similar visual quality." - and I bet they mean "almost the same quality".

Init buffer sizes between calls
May the source be with you

jj2007

Thanks, Timo. Right, even a mov UrlComp.dwUserNameLength, 1 is sufficient. It seems that if you pass a pointer to a buffer, the length must be at least one even if you don't get a text back.

A snippet that allows to copy a table e.g. from Excel and paste it here:

include \masm32\MasmBasic\MasmBasic.inc
  Init
  Let esi=Clip$()
  .if Len(esi)
Let esi=Replace$(esi, CrLf$, Chr$("[/td][/tr]", 13, 10, "[tr][td]"))
Let esi=Replace$(esi, Tb$, "[/td][td]")
Let esi="[table][tr][td]"+esi+"[/td][/table]"
Inkey "Put table on clipboard (y)?"
If_ eax=="y" Then SetClip$ esi ; put table on the clipboard
  .else
MsgBox 0, "No text on clipboard, sorry", "Hi", MB_OK
  .endif
EndOfCode
