Found some hiking companions. Sadly not for the Wicklows, but the Franconian Switzerland which isn't bad either. Had a good start. Didn't find our way and went to the opposite direction. Some pub visits helped us to reach our final destination. Continued my walking excercises in Olpe. What an enchanting landscape! Maybe I should move here, get myself a dog and settle down. They even started building a cinema! Missed the second hike to the right direction. Was too early for me. Booked the flight to Paris for mouse and me. Mouse has to get ready for the big fight as soon as he's back from Australia.

Smart Documents.

Yesterday I started the evaluation of the Microsoft's ISmartDocument interface for Office2003.
I started in a clean VM. I installed:
* Windows XP
* Office2003 and
* DevEnv 7.1 (C#)

Then I downloaded and installed the Office 2003 Smart Document Software Development Kit (SDK)

Next I tried to compile the “SimpleSampleCS” from the SDK.

It failed.

Some research showed that I had also to install the Office 2003 Update: Redistributable Primary Interop Assemblies.

Finally I was able to compile the project.

Next I tried to activate the smart document by simply opening the “SimpleSample.doc” in Word 2003. I ran the “setpolicy.bat” script and then the “DisableManifestSecurityCheck.reg” file. Then I opened the “SimpleSample.doc” and was asked to “Download the XML expansion pack”. After answering the security question with “no” I was able to get the sample working. (Other orders of invoking the scripts lead to the failure of loading the expansion pack”. I took me quite a while to figure that out. I even installed the .NET 3.0 Runtime Environment --- but I believe that is not required.).

Finally I was able to see the following “SimpleSampleCS”:



The overall architecture of “ISmartDocument”s is based on custom schemata to which actions can be attached. Quite simple but I gives custom schemata a meaning of the end.

The question I'm interested in:
* How is this work related to alien attributes and metadata in ODF? And
* what do we have to do to provide a competitive environment in OOo and ODF?

The prototype of text grid enhancement is available and the patch is under review now. Anybody who is interested in it could check out the patch from the cws cjksp1.

Today, I happen to find that there are quite many text grid issues open in Issuezilla. I will look at them one by one and try to fix them. :)

Some issues wrt. text grid in issuezilla:

i53425:more flexibility in the grid layout
i73011:Chinese layout incorrectly with text grid

Please let me know if anybody has question about text grid layout. :)

I've had several requests for my RPM for freetype2 including sub-pixel rendering for openSUSE 10.2. So here are instructions on how to build your own, including my modified SPEC file. If you're in the USA it might be illegal to download my file, so this file is only for people who live in free countries. Or at least semi-free countries, like the UK.

1. Download freetype2 source rpm from http://download.opensuse.org/distribution/SL-OSS-factory/inst-source/suse/src/ - it might be a newer version by the time you come to download this.
2. Download freetype-2.3.3.tar.bz2 and freetype-doc-2.3.3.tar.bz2 from freetype.org.
3. Download freetype2.spec if your government will let you.
4. Install the source rpm: sudo rpm -ivh freetype2-2.3.1-7.src.rpm
5. Put the tar.bz2 files in /usr/src/packages/SOURCES
6. Put the spec file in /usr/src/packages/SPECS
7. Build the rpm: rpmbuild /usr/src/packages/SPECS/freetype2.spec
8. The built rpms will be in /usr/src/packages/RPMS/i586

Note that you will need to have any required libraries and tools installed in order to build this. It should just be the basic development tools I think.

Finally, I have sub-pixel antialiasing in openSUSE 10.2. For some reason, it was turned off in the 10.2 release because of something being broken. I haven't been able to find out what. But yesterday I got tired of waiting for it to be fixed, so I downloaded the alpha freetype package from 10.3, only to find that it also has sub-pixel antialiasing turned off. No problem - I just installed the source package, replaced the tar files with version 2.3.3 ones, edited the spec file to enable sub-pixel rendering, disabled the freetype2-bitmap-foundry patch (because it wouldn't compile with it in there), rebuilt the rpm and installed it. Hey presto - sub-pixel rendering!

Last time I blogged about getting fonts to look better in 10.1, I had a load of comments telling me I should just turn of antialiasing because text looks better without it. Well, I like antialiasing, and especially sub-pixel antialiasing. On my 1900x1200 display it looks great. So there!

Had to say good-bye to mouse. He'll travel to Australia. Again. Tried to smuggle myself into the luggage but I was too big. Hope mouse will at least send me a postcard. He is such a lucky mouse. My friend even bought chocolate for him.

There has been issues reported by GW users that Evolution hangs/suspends for a while when composing mails. We weren't able to reproduce the issue and respective gdb traces didn't give enough information. Lately, I started hibernating my laptop and when I resume from hibernation, I noticed that EDS started taking 100% CPU and when gdb is attached to the process... voila!!!.. EDS was running with 264 threads and most of it are waiting to update GW addressbook and rest are waiting to update GW calendars.

A little further investigation revealed that it was because of the combination of g_timeout_add()+hibernation. GLib stores the last processed time for g_timeout_add and when hibernated, the memory image is stored and restored, when resumed from hibernation. When restored, callbacks registered with g_timeout_add() gets called - as the difference in time during hibernation and resume satisfies the g_timeout_add() timeout value and that too in multiples of 100. Harinath (of Mono fame) helped me understand the GLib part and the fixes have gone in for GW and webcal provider.

The following user scenarios of text grid are under investigation.

1. When user creates a text document, the default paper mode of text grid is read from user preference settings. User can switch the default paper mode of text grid in text document options tab page. (Tools --> Options --> Text Document --> General) by clicking the check box "Use squared paper mode for text grid".

2. When import a Ms Word 97/2000 file (.doc), the default paper mode is treated as "standard paper mode".

3. When import a text document of the previous version of OO.org (.odt, .sxw), the default paper mode is treated as "squared paper mode"

4. When user is editing a text document with text grid.
if he switchs the paper mode from "squared" to "standard", the following behavior is used:
* line height = Max base text size + Max ruby text size
* lines per page = type area height / line height
* Max ruby text size = 0

if he switch the paper mode from "standard" to "squared", the following behavior is used:
* line height = type area height / lines per page
* Max base text size = line height * 2 / 3
* Max ruby text size = line height / 3

As mensioned before, there are two kinds of text grid layout which are used in CJK users. One is "squared page mode", the other is "standard (rectangle) page mode".

Per the text grid prososal approved by ODF TC, the style:layout-grid-standard-mode property is added to specified which kind of text grid is used for the document.

In order to ensure that either “sqaured mode” or “standard mode “is used for the whole document, the style:layout-grid-standard-mode property can only be set for the default style of the “page-layout”. When the style:layout-grid-standard-mode attribute appears inside a style:page-layout definition, then the attribute MUST be ignored.

Global setting entry for selection of which kind of text grid layout is used for the whole document. (Tools-->Options-->OpenOffice.Org Writer-->General)


When the "Use squared page mode for text grid" is checked, the original tab page of text grid is used.


When the "Use squared page mode for text grid" is unchecked, the following tab page of text grid is used.

Today I came across a E2K_DEBUG trace forwarded to me from a Beta customer that had OWA url like http://www.example.com/CookieAuth.dll?Logon and after some googling found out that, when a Mailbox server is behind a Microsoft ISA proxy server, the OWA url gets redirected to the above link. Evolution-exchange now will support Microsoft ISA server as well.
