working with athens balloon

Hi,

I would like to get Athens for Balloon loaded by default in a Moose
image. The idea would be to make it easy for people to migrate to this
interface, to make the code ready for Cairo.

In the process of testing it, I noticed that the text examples do not
work with StrikeFont. Please note that we are using Pharo 1.4.

I tried it by doing the followings:
Gofer new
squeaksource: 'Athens';
package: 'ConfigurationOfAthens';
load.
((Smalltalk at: #ConfigurationOfAthens) project version: #development)
load: 'Athens-Morphic'.

And then:
AthensTextRenderTest test1.

The problem seems to be caused by a missing method: StrikeFont>>getPreciseAscent

@Igor: Is this a missing method, or is it something else? Would it be
difficult to fix this?

Cheers,
Doru

normally you will not have to migrate except if you want to break the layering of athens and/or
if you want to use cairo hyper specific features.

Again Athens provides an API and Morphs should be migrated to use this API.
so as a transition period each morph should get its drawOn: method rewritten as a drawOnAthens:

Then you as a Morph user you do not have to change anything.

In general the font model has to be totally rewritten.

I know what Athens is :). I meant to say that the client code needs to
me migrated (EyeSee, Roassal) to the new Canvas. Once this is ready we
will be prepared to use Cairo which technically right now requires
extra things: install Cairo, use another VM.

Ok, but until the text will work with Balloon Athens we cannot do much
because both EyeSee and Mondrian need that API.

Re: working with athens balloon

Hi, Tudor.

Yes, i did not implemented support for Strike fonts.
Because strike fonts are not scalable, and because no way they can be
correctly rendered by Athens:
fonts holding a pre-rendered glyph with subpixel accuracy... which
working well as long
as you don't rotate/scale the bitmap.. and if you do, then output is
even worse than gray-scale)
So it is useless, and that's why i didn't added support for them in a
first place.
But if you need it, i can add it. It should be easy to do. Tell me if
you need it.

I am currently working on bundling cairo library with VM
i thought it will take less time, but ... this stuff is terrible to
compose & build unless you are on linux.
I should finish Mac build in a few days (actually i always think that
it will be this day, but then yet another idiosyncrasy prevents me
from finishing it :)

igor if this is simple may be this would be good so that people can get started
and put more pressure on you.

I see. If it is not expensive, I think the support for StrikeFonts

Like that, once we have migrated the code to the new API, we can
simply switch to the Cairo/Pango backend. Or do you have another
proposal?

On another note, how do I make "AthensTextRenderTest test1." work? I
mean how should I initialize the default font (or how do I pass it to
the AthensTextScanner)?

ouch.. looks like extension methods is wiped from LogicalFont..
i will add them back..

But in overall , i want to tell you the situation:
as you may see, there is no high-level API defined yet in
Canvas/Surface for text rendering.
And i am going to introduce it , once i'll deal with VM bundling..
because telling people to install cairo and do jumps and hops just to
see it works is
wasting a time.

Now the idea how i want to introduce it is simple.
You can use any object as font (as long at it should conform to some
minimal font protocol,
which has to be defined). I don't like to inherit AbstractFont
protocol, because it is too
pixel-wise centric.
Now, to start using that font on a surface, once should tell font:

renderer := font getRendererOn: surface.

this should answer a subclass of GlyphRenderer, which then can be used later
to render the text on given surface using given font.

renderer setPosition: ..
renderer renderGlyphsIn: 'abcde' from: 1 to: ('abcde' size)
etc.

of course there is missing some convenience protocol(s), but just to
give you an idea.

About pango:
pango is framework for text layout, not rendering. So, it can be used
along with Athens,
but it will be never an integral part of Athens.

In Athens, i don't want to provide a high-level and highly complex
semantics for text layout,
because it is a separate domain and you can spend whole life there.
Athens should support only basic drawing operations, like draw
character span at certain position.
The rest (layout) should be handled externally.

Exactly. This is what we need for engines like EyeSee and Roassal.

I know that. I should have not mentioned Pango :)

Re: working with athens balloon

I gonna introduce a naive protocol in canvas for drawing text.

Something like this:
can setFont: font.

can setPaint: (Color black alpha: 0.3).
can drawString: 'abc'.
can translateX: -1 Y: -1.
can setPaint: (Color red).
can drawString: 'abc'.

Re: working with athens balloon

Thanks.

The StrikeFonts are still not supported by default :(. The problem is that until the VM will have the right plugin by default it's going to be difficult to adopt this canvas widely.

Btw, where do I get the VM plugin (for Mac and Windows)?

Normally on the latest cocoa VM (may be I got it wrong)
Now igor worked nights (and day) to get the plugin managed nicely with CMake.
I think that what he did is really a good step forward to avoid statically linking old libraries :).
It also means that we will be able to provide users a real experience (no sudo port universal bullshit).
