Thanks for all your answers.
Indeed, I am mostly interested in "tiny" browser supporting javascript 
and CSS under directFB. It seems the only browser that fulfill my 
expectations are running on top of GTK-DFB (~47MB). It is to much. Is 
there any way to decrease GTK-DFB place ??
Are there other browsers supporting natively directFB than Links ???

Hi,

I used the TTF font rasterizer to make more than 30000 pngs for Chinese font.

http://linuxfromscratch.org/pipermail/links-list/2003-November/004302.html

And after making Links, the size of the execution file is 114.3M ??.

I can?t run the program, as I run ./links, the process is killed instantly. :-(

 

So I want to render the texts by DrawString() instead of Blit() of the DFBSurface API (directfb.c directfb_draw_bitmap() ), just drawing the texts with a ttf font directly rather than bliting from the pngs

Is it realizable? Thanks.

Message-ID: <D00EA8F7A459974590650D95FEC78FF701705937@twmail13.coretronic.com>

Hello,
I am a french developer and I am trying to use links in an embedded linux Set Top Box. I am now testing links which seems to be a very interesting project using DirectFB displaying system.
I know that links doesn't support CSS or style features in HTML code, but I need to display some links (<a href=..> tag) on DIrectFB, wherever I want, by using coordinates.

I've already looked for some solution in directfb.c but I didn't find the method or function to display some text and links. Moreover I barely understand how links 'display system works.

What I would like to know, is :

1. How does links do to display some text on DirectFB ?



View_gr.c g_text_draw() #265 g_print_text()

Dip.c g_print_text() #1804 print_letter()

Dip.c print_letter() #1707 gd->draw_bitmap()

The gd->draw_bitmap() is directfb.c #335 directfb_draw_bitmap()

It blits the pngs to data->surface


2. How does links do to display data like "links" on DirectFB ?

 

Maybe you can trace html.c html_a() ?


I hope there will be a possibility to modify this method or to replace it with a new one.
Thanks in advance for your advice.

You probably have set some limit on virtual memory or executable size in your
system. Try to increase it. Use ulimit.

It shouldn't be a problem, those 114M just lie on the disk and are mapped into
memory only on demand and then freed again. Shouldn't make difference if the
fonts are mmap()ed or compiled into the binary like this.

I just wonder how long the compilation of font_include.c took with 114MB of
fonts :) Didn't your gcc explode? :)

Yes, but will it then run on OS/2 Pmshell, AtheOS GUI, FreeMint and other
obscure operating systems I actually even never saw in my life? Maybe the font
library doesn't compile on them.

It will also be slower and/or uglier. To antialias properly you have to first
draw in a huge resolution and then scale down. Any other algorithm IMHO
produces incorrect results.

Are these fonts under a licence compatible with GPL? It would be nice to add
these PNG's into Links with some switch like --enable-chinese.

I run Links on embedded linux without swap, and the memory on board is only about 58MB. :(

The font_include.c is 317MB. After compiling, The font_include.o is about 110-120MB.
When making Links, it cost more than 80% of system memory. 
I just wrote a script that sleeps to midnight and then make, so I don't know the actual time making Links with the more 30000 pngs.

I tried using DFB DrawGlyph() instead of draw_bitmap() in print_letter(), and the performance is really very very poor...
I think the reason may be that I create the font and then release it for every character; 
I'll try to reduce the times of font create()...

I'm not sure if it is under a license compatible with GPL...

114MB shouldn't go into the semiconductor memory, but into the virtual memory.
It's like several GB. Mikulas, can you comment on this?

If you have CPU with paging, it should be demand-paged --- i.e. it loads 
only those pages that it requires and releases them if free memory goes 
low.

If you have CPU without paging (*-nommu Linux kernels), it will load the 
whole binary, there is no help for it.

You can change in font_include.c unsigned char font_data and struct letter 
letter_data to const unsigned char font_data and const struct letter 
letter_data to see if it helps (with some weird dynamic loaders it may 
help), but if your CPU has no paging, there is no improvement possible.

Just compile the rasterizer below
http://linuxfromscratch.org/pipermail/links-list/2003-November/004302.html
Use ./rasterizer dump_all=1 fontfile.ttf to generate your own pngs for your font,
And copy the pngs to Links/graphics/font/, rename the png folder according to other folder

Run the generate_font at Links/graphics
After that, you'll get a new font_include.c
Make Links with it, you'll get the new binary containing your font

I am attempting the write a script to test netlogin web authentication using links.  There are many clunky gui test tools to do this, but I hoped that a cli based browser with javascript might be a better solution.

Process:
1) attempt to access a web page and you get redirected to the login page. (I need to verify the page content).  Would links -dump http:/www.bob.com work?
2) when a login page is reached a javascript login screen appears.  I need to be able to enter the user name and password in the auth window.  Then verify the original attempted web url is reached.

I do not see any documentation of cli commands such as links (-dump) on the Twibright page.  Is there documentation on all available args?

I noticed that some other flavors of links support browser scripting.  Is this what I am looking for.  Of course they do not support java script... so it doesn't matter.

Thank you for your time and patience.

It's in man links. If you don't want to install links just to see the manpage,
then download the tarball file and look at it using "man ./links.1" (linux)
or "man -M . 1 links" (OpenBSD).
