Incorrect text rendering in GDI mode - maa3 - 07-30-2023

Hello,

Windows 7 SP1
CentBrowser 5.0.1002.354 (32 bit) (Portable), DirectWrite disabled

screenshot for comparison:

   

top = reference rendering (MS Office 2007 Word)
bottom = CentBrowser rendering

as you can see, the CentBrowser renders too dark pixels (maybe incorrect gamma?)

so try turning on directwrite

Yes, changing gamma value was asked by some users(when DirectWrite is disabled).
They complaint the default rendering is too light.

RE: Incorrect text rendering in GDI mode - maa3 - 08-01-2023

Some users are too stupid.
With incorrect gamma, diagonal lines look too black compared to vertical and horizontal lines.

Do you think we need to change back?

no, why? who needs a light (soapy) font, let this flag not be turned off and that's it. Leave it as it is now

so why did you turn off the flag? really "Some users are too stupid."  Biggrin

Any examples of what are they talking about before such a radical changes? I'm pretty happy with the lines.

It was decided at least four years ago.
I remember they were asking for the same rendering effect of Firefox.

@Centbrowser team :

I don't know if this is feasible, but why not adding an option to give users the power to change the gamma value, with some kind of slider (with pre-defined values) or an input box ?

Problem is :
  • yesterday, some users asked for much darker gamma value
  • today, some users ask for much lighter gamma value
  • tomorrow, some users will probably ask for another gamme value

If you change gamma every time someone asks for it, this will be a forever job. And you will never satisfy all users, as everybody has its own opinion on the subject (it's like asking 10 persons what is the best color, you will probably have 10 different answers Dodgy ).

ps : I'm not trying to say you shouldn't change it, or that X is right or Y is wrong (I'm using the browser as it is, with directWrite, in fact...)

Definitely yes.

There is no problem - there is only one correct gamma value, the rest are wrong.
If you're a calculator developer and some users want 2+2=5, would you do that?
You can use font gamma tester.
Firefox show correct gamma, Cent browser not:
