Font-rendering version 5.3 [closed]
Can someone form the developers team tell me if the new font-rendering engine will be improved?
In Calc I use the standard Liberation Sans font at 9 pixels, and some letters are really squeezed together. This happened after updating to version 5.3. As I understand a new font-rendering engine has been implemented in version 5.3, but can we expect some improvements on the future versions? This letter-squeezing is not good :-(
Have a look at the image and especially the word 'Amsterdam'.
As you can see in the image there is a lot of space between the first A and m.
But then the letters ste are totally squeezed together.
Will this be improved in a future version of LO?

Took a look at it today - appears to just be a hinting artifact due to the small type size on screen.
Zoom your spreadsheet to 200% and the letter spacing issues disappear. The font render engine then has enough pixels to display the font with less shifting to line-up with screen pixels.
And the 9pt font prints just fine.

Nothing to fix in LO.
Did you look at my second image? It was fine before, and now it isn't anymore. Yes, when I zoom in it gets better ... but shouldn't it be fine in the first place, at 100% view? Don't you agree with that? I don't know how all of this rendering and hinting works. All I see is that something that was great is now not anymore. The big question is .... can it be fixed? :-)
No, I do not agree.
Read the hinting explanation I linked to above. It explains the issue.
There is nothing to fix. It is working as expected.
You are looking at it from a technical point of view. I am looking at it as being a user. All i see is that there is a difference in rendering before and after version 5.3
Before version 5.3 at normal 100% view the rendering was better than it is now. I'm not looking at technical aspects. I'm just looking at what I am seeing. I assume we both see the same? Then what makes you think the new rendering where letters are squeezed together is better than the earlier type of rendering?
I just compared v5.3.0.3 to v5.2.5.1 and I can see the difference you mention. It does look better on the previous version. The new font rendering engine obviously works differently.
I also tested the Lato font at 9pts on both versions. It looks good on both versions. Lato has very good hinting and it was designed to look good on screen.
Verdana and Tahoma were also designed to look good on screen. Tested Tahoma and it also looks good on both versions. Wine includes a free version of Tahoma
I can understand your frustration, unfortunately it is not likely anything can be done.
The new font rendering engine works differently and it is not going to be changed.
Hmmm ... Maybe I will try running Liberation Sans thru some font hinting tools and see if it improves the rendering at 9pts - like Lato and Tahoma
Thank you for taking time to answer my questions. I appreciate that.
I do not have the Lato font installed, and I like to use a font that comes bundled with LO. I like how Liberation Sans looks and that's why I choose to use it. It really is a shame that the rendering is quite crappy now :-s It used to be great.
I have no idea how these font hinting tools you are mentioning work, but if you can improve it, I myself and presumably many others will be very very happy!!! Thanks in advance!!!!
Someone recently asked what fonts are included in LO - and I could find almost nothing at all. So for the last few days I have been working on a LibreOffice Font Guide. When creating the 100 font specimen pages I have found a couple other anomalies to investigate.
Will check-out those and the hinting issue tomorrow.
Many thanks in advance! I truly hope the issue with Liberation Sans will be resolved.
I looked at the word "Amsterdam" on this web page using Linux FireFox 45.7.0 ESR with at a variety of bigger and smaller zoom settings, and it does not appear to have the space after the A, like @LibreGuy's example image is showing. So I have to agree that the way that LO is drawing fonts on the screen could be better.
