Hi,

I tried to debug a bit more.

First, I noticed that Roassal was using the FreeTypeFont and Trachel the LogicalFont. I now changed Roassal to also use the LogicalFont. This did not solve the issue, but it does ease the comparison. (Just ensure that you clean the cached fonts from ROFontOrganizerAthens if you already worked in the same image before loading the new code)

Then, I noticed that even Trachel does not yet quite work: some letters still appear larger than others. However, at least in the case of Trachel, the width of the characters correspond to the size of the rendering (and this seems to still be a problem in Roassal).

See attachments:

Inline image 1

Inline image 2

The strange thing is that if you debug, it seems that the code is basically the same in both cases. I am stuck. Ideas?

Look at the level of the canvas's creation, maybe the properties are not the same...

Hi,

For Roassal, I loaded the older packages of Athens-Core and Athens-Cairo :

Ancestors: Athens-Cairo-SebastianTleye.50

And I have no problem in font displaying !

In the newer version, they have implemented the text rendering with NativeBoost.

As Roassal2 works fine with the newer version, I don't know if this is a problem with Roassal or with Athens-Cairo.
Maybe you should look at it ?

Cheers,

Vincent

Thanks, Vincent.

I integrated your change in Trachel. It works well now.

Hi,

The following code solve the issue under Roassal2 (Tested under Linux) :


TRLabelShape class>>getFontForSize: aNumber
    ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

For Roassal, the fonts used are the same that in Roassal2 so I don't think that is the problem.

But it seems that the Athens Font Renderer has been changed (CairoFreetypeFontRenderer) the 4 February (Athens-Cairo-MarcusDenker.62).
This the only thing I see with my knowledges on Roassal. And I don't know how to solve it. Maybe does Alexandre know ?

Cheers,

Vincent

But, does anyone know what has changed recently in this area?

My guess is that the change comes from Pharo. Or?

Hi Vincent,

What is the status on this?

At this moment, essentially all visualizations containing text are broken (Roassal, Roassal2, GraphET). This is a show stopper.

Let me know about your progresses with the font problem.
Everything should be treated in Trachel I have the impression.
I have found a solution to fix the bug:

TRLabelShape class>>getFontForSize: aNumber
    ^ LogicalFont familyName: StandardFonts defaultFont familyName pointSize: aNumber

In this, it creates an other font with the good size. Because if you don't do that, you always have the same problem.

"StandardFonts defaultFont familyName" should be enough to get the font to use. Maybe we have to change something else in Roassal2.

No problem to use Roassal 2 instead !

But I have the same issue on the examples.

Which issue?

The font display issue..

  RTDowserExample new coolStuff :

<ghcgceef.png>
That is under Linux. It's not very readable.

And I think there is the same issue with W7
If you want some help, I can. But I need some pointers :)

I have the impression, that the class TRLabelShape has to be improved.
For example, consider the following method:
-=-=-=-=-=-=-=-=-=-=-=-=
TRLabelShape class>>getFontForSize: aNumber
        ^ LogicalFont familyName: 'Arial' pointSize: aNumber
-=-=-=-=-=-=-=-=-=-=-=-=

The font name is hardcoded, which is not a good idea since you may have a different font set on your machine. It would be great to use the installed font, used by Pharo.

That a good idea ! Because under Linux, the Arial font doesn't exists....


But with this :
LogicalFont familyName: 'Source Sans Pro' pointSize: 12
You have :
<ijdgccca.png>

I will search how to use the system fonts.
By the way, have you tried: RTExample new rotatingLabelsAnimated

That doesn't work :( rotatingLabelsAnimated is not a valid message to a RTExample ...
:-)

Hi!

I have spent a lot of time on trying to understand font, and many bugs are
still there. I would indeed be happy to have help on this...

Why trying to use Roassal2 instead? Your code will stay the same, but it
will directly use Athens.

Cheers,
Alexandre

Hello everyone,

Under the latest version of Moose, I am confronted to some problems of

text displaying with Roassal. The text letters are not in the same font.

A first example :
<dfcbaide.png>
A second example :
<cagichjd.png>
And if I zoom in or out, the text is correctly displayed...
<ceciibjj.png>

That's strange..

I am on Ubuntu x64 and I have the same issue on W7.

Cheers,

Vincent
