pch — 2008-12-04T09:59:48

Hi list, I would like to write a C++ program in Gtkmm which write blue text in DrawingArea. I don't know how I can do this. I can write black text but can't change color. I try change color like this: Pango::Attribute attr; attr.create_attr_background(100, 200, 700); Pango::AttrList attrList; attrList.change(atrybuty); I can compile program but when program is execute then it is terminate and I can see: "Pango-CRITICAL **: pango_attribute_copy: assertion `attr != NULL` failed". How I can write blue text. Please, help me. Thanks pch

.. and that answer saved me from getting more and more frustrated this sunday! Thanks! For the next one, and for the search engines, this is what I used to install rrdtool: ./configure CPPFLAGS="$(pkg-config --cflags pango pangocairo pangoft2 pangox)" LDFLAGS="$(pkg-config --libs pango pangocairo pangoft2 pangox)" make told me I needed libexpat, but that's available on the slackware packages page, so I installed that, and make && make install ran perfectly. Thank you, very much! Henk te Sligte 2008/11/30 Wouter Bolsterlee xs4all.nl>:

trying to build some pango code

Henk te Sligte — 2008-11-30T13:21:45

Hi guys, I'm kind of lost around here, and I hope one of you can help me out. I'm trying to build rrdtool from source (slackware doesn't have a package for it), and the only reason it doesn't work is because of pango. The testscript is as following: /* confdefs.h. */ // A lot of defines which aren't necessary for this.. /* Override any GCC internal prototype to avoid an error. Use char because int might match the return type of a GCC builtin and then its argument prototype would still apply. */ #ifdef __cplusplus extern "C" #endif char pango_cairo_context_set_font_options (); int main () { return pango_cairo_context_set_font_options (); ; return 0; } And by trying to build this, I collected a lot of -I's and -L's, but I don't know which one to use, right now I have the following: gcc -o conftest -g -O2 -D_GNU_SOURCE -fno-strict-aliasing -Wall -std=c99 -pedantic -Wundef -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline -Wold-style-definit

[te-IN]Consonant+halanth+Consonant+halanth as single characterrendering

arjuna rao chavala — 2008-11-29T07:27:40

Hi, I find the biggest rendering related localization problem of linux with Telugu is the inability to render Consonant+halanth+consonant+halanth+space as one letter. Currently the las halanth appears as an individual character after the conjuct with 'a' vowel. These instances are becoming common, as more foreign words are transcribed in Telugu. If we have to get the same effect, for linux we have to code consonant consonant+halanth+consonant+halanth+zwj But this breaks on windows uniscribe, as they are rendered as individual consonant halanths. Please see the bug and the attachment at it to understand the problem, http://bugzilla.gnome.org/show_bug.cgi?id=516947 Bug 516947 – [te] consonant ending (halanth) of conjunct of two or more consonants in telugu is not rendered correctly Whether any indic fixes in pipeline plan address this? Which module pango-indic or harfbuzz needs to be fixed for this? Thanks Arjun _______________________________________________ gtk-i18n-list mailing list gtk-i18n-li

Re: Pango/Cairo with OpenType handling

Behdad Esfahbod — 2008-11-18T14:41:04

There are in fact three variants of the PangoCairo FontMap. The one used on Linux is a subclass of PangoFcFontMap. So, what you need to do is to check whether your font is a PangoFcFont using PANGO_IS_FC_FONT(), and if it is, you can call pango_fc_font_lock_face() on it. Regards, behdad

New FontForge build that depends on Pango has slow startup time

Dave Crossland — 2008-11-17T17:25:58

Hi, FontForge now uses Pango for its UI text by default! I wonder if any Pango experts could take a quick look at this and help GWW to diagnose what is making FontForge startup very slow? ---------- Forwarded message ---------- From: silcom.com> Date: 2008/11/16 Subject: [Fontforge-announce] New FontForge build To: fontforge-announce< at >lists.sf.net First release with Pango and Cairo. The first time you run fontforge with Pango something takes several minutes to initialize itself. This delay does not occur on subsequent invocations. The version of Cairo available from fink on the mac is so old that FontForge can't use it. The default fontconfig setup on the mac does not seem to find any outline fonts (reverting to bitmaps). Create a ~/.fonts directory yourself, and put some fonts there. Pango crashes on my cygwin system, so the cygwin build does not contain either Pango or Cairo.

Re: FYI: "Requirements of Japanese Text Layout" W3CWorking Draft

2008-11-16T17:56:24

Dear Sirs, I'm sorry for posting 2 days after the deadline. Followings are my comment on "Requirements of Japanese Text Layout W3C Working Draft 15 October 2008" 2.2.2 The description of "imaginary body" needs further informations with figures, especially if they are different from "em" used in the typography of Latin alphabets. For the basic mixed text composition of Japanese and Latin in horizontal writing mode, the "imaginary body" of Japanese font and "em" of Latin should be matched? In addition, the requirement of the surrounding space between the letter face and imaginary body should be described in more detail. I think the primary purpose is to keep Japanese letters isolated. However, it might be arguable if the surrounding space is required for punctuations, Box Drawing (U+2500 - U+257F), and Block Elements (U+2580 - U+259F). The "imaginary body" in the draft might be what ISO/IEC 9541-1: 1991/Amd.2:1998 had ever called as "the extended body". If they are same and no need to use different termin

Pango/Cairo with OpenType handling

Jeremy Smith — 2008-11-13T20:20:40

I'm trying to figure out how to use the OpenType font handling functions as described here: The problem is that in order to do anything with OpenType, I first need to get a PangoOTInfo. I can only get a PangoOTInfo if I have an FT_Face, which is specific to FreeType. I want to use Cairo as the backend. Is this possible? I can't seem to figure out any way of getting a valid FT_Face without using FreeType or Xft. If anyone could just tell me the simplest way to get an FT_Face, that would be perfect. I've tried using pango_font_map_load_font() to get a PangoFont, then passing that to pango_ft2_font_get_face() (which is deprecated), but I get a warning about how the font is not valid: Pango-WARNING **: pango_ft2_font_get_face called with bad font, expect ugly output So clearly I'm doing something wrong. Thanks for any advice (I'm brand new to using Pango, as you can probably tell) Jeremy

Leak in the pango cairo example?

Sebastian Bauer — 2008-11-12T13:43:34

Hello, currently I'm playing a little bit around with pango. However, in my application I get a memory leak which, by using valgrind, could be addressed to pango, in particular, to the pango_layout_get_size() function. Therefore I tried the cairo example, as provided at http://library.gnome.org/devel/pango/unstable/pango-Cairo-Rendering.html in order to check, whether my code is wrong. However, even with Example 1 that is listed there, I get those leaks. You'll find the output of valgrind attached to this mail. Is there anything that can be done about the leaks? I'm using pango 1.20.5. Any help is appreciated! Thanks in advance!

Problem using Pango with .Net

Isenko Evgeny — 2008-11-10T06:49:30

Hello! When using Pango in C# (MS Visual Studio), I encountered several strange problems that I cannot explain. It is 80% sure that I've made some mistake implementing Pango binding for C#. Does anyone has such experience? The following code works fine until I try to make some special changes. In particular, there are two problems. 1) pango_font_description_set_size doesn't work. Moreover, whenever I try to call this method, boxes appear instead of letters. The funny thing is that pango_font_description_from_string works fine. At present, I change font size by putting needed value into the string parameter. :-) 2) Whenever I try to call pango_matrix_rotate, boxes appear instead of letters. Also, pango_context_set_matrix doesn't seem to work. (The below code is simplified a little bit for readability). // This is how I implemented some dll bindings [DllImport(pango)] public static extern void pango_matrix_rotate( [In, MarshalAs(UnmanagedType.LPStruct)] PangoMatrix pango_matrix, double degrees); [DllIm

Using Pango in C#: encoding problem

Isenko Evgeny — 2008-11-04T08:06:49

Hello! I'm trying to use Pango in C# (MS Visual Studio), but cannot figure out how to convert C# strings to the native Pango format (char*) and vice versa. The non-unicode letters are drawn without problems, but when I try to put some unicode text, the output is unreadable. First of all, I confirmed that pango and cairo are working well. For this I got the sample string with pango_language_get_sample_string and put it in pango_layout_set_text. It was perfect for any language. But when I try to convert it to the C# string, I get only unreadable mess. Below is the code. Would someone tell me where I was wrong? [DllImport("libpango-1.0-0.dll", CharSet = CharSet.Ansi)] public static extern IntPtr pango_language_get_sample_string(IntPtr language); /* Some code here */ IntPtr samplePointer = PangoCairo.NativeMethods.pango_language_get_sample_string(myLang); string outputStr = Marshal.PtrToStringAnsi(samplePointer); When I use Unicode instead of Ansi, the result becomes even worse... Thanks for any help.

Not right now. It's not really hard to add to pango if this is useful. What is your usecase? Note that pango selects between the Unicode ellipsis character, the Unicode Ideographic ellipsis character, and "...", whichever is more appropriate. behdad
