Powerful Unicode Text Editor

14 Enero, 2008

Edit Any Text File with EditPad Pro

EditPad Pro is a powerful text editor for Windows. You can edit all text files with EditPad Pro. Open text files saved on Linux, UNIX and Macintosh computers, or even text files from old DOS PCs or IBM mainframes. EditPad Pro preserves the file’s compatibility with those systems, unless you explicitly convert it. You’ll never have to worry about being unable to open a text file, and you’ll always be able to save your files in a format that people with less flexible text editors can read.

EditPad Pro handles DOS/Windows, UNIX/Linux and Macintosh line breaks. Open and save text files encoded in Unicode (UTF-8, UTF-16 and UTF-32), any Windows code page, any ISO-8859 code page, and a variety of DOS, KOI8 and EBCDIC code pages. Convert files between any of these encodings.

Type in Any Language or Script

You can use any keyboard layout and any IME (input method editor) for any language or script that Windows provides in the Regional Settings in the Control Panel. If you set the default encoding in EditPad to Unicode, you can use all languages and scripts at the same time in a single file.

You can even use exotic scripts that don’t have legacy Windows code pages, or built-in support from Windows. EditPad Pro is fully compatible with all your virtual keyboard drives, such as those created with the Microsoft Keyboard Layout Creator (MSKLC).

EditPad Pro’s character map allows you to insert any character supported by the current file’s encoding, which is very convenient for working with characters or languages that you cannot type on your keyboard. The status bar can indicate the code page numbers and Unicode code points of characters as you type or scroll through a file.

The only feature missing in EditPad right now is proper right-to-left support for Arabic and Hebrew. This support will be added in an upcoming version.

Code Pages Supported by EditPad Pro

EditPad Pro supports a very wide range of code pages used to save text files on Windows computers and other platforms. You can instantly convert a file between any two encodings by selecting Convert|Text Encoding in the menu, or re-interpret a file using a different encoding in case EditPad Pro’s auto-detection fails. You can specify different default encodings for each file type.

Unicode

Unicode text files can store text in any language known to humanity. Modern globalized applications often use UTF-8 or UTF-16 to save text files.

  • UTF-8
  • UTF-16 little endian
  • UTF-16 big endian
  • UTF-32 little endian
  • UTF-32 big endian

All Windows (ANSI) Code Pages

Windows applications that don’t use Unicode save text files using one of the Windows code pages, often called “ANSI” code pages in technical documentation for Windows. EditPad Pro supports all single byte (Western languages) and double byte (Far East languages) code pages, allowing you to open any text file created on a Windows computer.

  • Windows 1250: Central European
  • Windows 1251: Cyrillic
  • Windows 1252: Western European
  • Windows 1253: Greek
  • Windows 1254: Turkish
  • Windows 1255: Hebrew
  • Windows 1256: Arabic
  • Windows 1257: Baltic
  • Windows 1258: Vietnam
  • Windows 874: Thai
  • Windows 932: Japanese Shift-JIS
  • Windows 949: Korean
  • Windows 936: Simplified Chinese GBK
  • Windows 950: Traditional Chinese Big5

All ISO-8859 Code Pages

Applications that don’t use Unicode running on Linux and other UNIX variants usually save text files using one of the ISO-8859 code pages. EditPad Pro supports all ISO-8859 code pages, allowing you to open any text file created on a Linux computer.

  • ISO-8859-1 Latin-1 Western European
  • ISO-8859-2 Latin-2 Central European
  • ISO-8859-3 Latin-3 South European
  • ISO-8859-4 Latin-4 North European
  • ISO-8859-5 Cyrillic
  • ISO-8859-6 Arabic
  • ISO-8859-7 Greek
  • ISO-8859-8 Hebrew
  • ISO-8859-9 Latin-5 Turkish
  • ISO-8859-10 Latin-6 Nordic
  • ISO-8859-11 Thai (TIS-620)
  • ISO-8859-13 Latin-7 Baltic Rim
  • ISO-8859-14 Latin-8 Celtic
  • ISO-8859-15 Latin-9
  • ISO-8859-16 Latin-10 South-Eastern European

DOS (ASCII) Code Pages

EditPad Pro supports a wide variety of code pages used by the legacy DOS operating systems like MS-DOS and PC-DOS. These code pages include the famous “box drawing symbols” used by text-based DOS applications to simulate graphical menus and windows.

  • DOS 437: United States
  • DOS 737: Greek
  • DOS 775: Baltic Rim
  • DOS 850: Western European
  • DOS 852: Central European
  • DOS 855: Cyrillic
  • DOS 857: Turkish
  • DOS 860: Portuguese
  • DOS 861: Icelandic
  • DOS 862: Hebrew
  • DOS 863: Canadian French
  • DOS 864: Arabic
  • DOS 865: Nordic
  • DOS 866: Cyrillic Russian
  • DOS 869: Greek 2

KOI8 Code Pages

The KOI8 encodings are very popular for encoding Russian text files. If you receive files with text in Russian, they’re likely to be encoded in KOI8 rather than in Windows 1251 or ISO-8859-5.

  • KOI8-R: Russian
  • KOI8-U: Ukranian

EBCDIC

The EBCDIC encodings were the de facto standard when computer files were saved on punch cards, and are still used by mainframe systems from IBM and other vendors. EditPad Pro supports the more commonly used EBCDIC encodings.

  • EBCDIC 037: US & Canada
  • EBCDIC 424: Hebrew
  • EBCDIC 500: International
  • EBCDIC 875: Greek
  • EBCDIC 1026: Turkish

“I’ve been using EditPad for several years now, and it has always been my favorite plain text editor. And since I often need to read files using different code pages, or convert between them, I’m very glad of the new Unicode capabilities of EditPad 6.0.0 (especially since they’re also available on Windows 98!). I’m certainly going to use EditPad even more than before. Thank you very much, and keep up the good work”!

A Truly International Text Editor

It’s no surprise that EditPad Pro is one of the few Windows text editors that you can use to edit text files in any language or script. While most text editors boldly advertise Unicode support, they often have trouble with anything outside the repertoire of Western European characters familiar to American programmers.

EditPad Pro is the brainchild of Jan Goyvaerts, who grew up in Belgium, a small country in Europe. At school Jan had to study Belgium’s three official languages (Dutch, French and German), as well as English. Nowadays, Jan lives in Thailand, with its unique script that writes vowels around the consonants in all four directions, rather than just from left to right. Obviously, he wants his text editor to work perfectly with all these languages.

EXIF, archivos jpg

13 Enero, 2008

La cabecera EXIF de los archivos JPG se utiliza para guardar metadatos, datos/información relacionados con la imagen. Lo que muchos no saben es que algunas camaras digitales guardan tambien en esa zona un thumbnail (pequeña imagen) de la propia foto que se saca. Algunos programas de edición de imagen no tocan esa cabecera EXIF, por lo que podemos encontrarnos con una foto/imagen que tiene en la cabecera otra foto/imagem sin retocar. 

****************************** 

Las cámaras digitales guardan pequeñas imágenes llamadas “thumbnail” (“miniaturas”) dentro del contenido de grandes imágenes. Estas imágenes suelen perderse en posteriores procesos, pero a veces estos “thumbnail” contienen información significativa editada en la imagen principal. Automated Script baja archivos JPEG de la web y los analiza en busca de diferencias entre la imagen principal y el “thumbnail” y pone posibles candidatos en base de datos MySQL. Los resultados pueden verse en esta pagina. La idea en sí misma me vino de afuera. Hubo un famoso caso con Cat Schwartz y ciertas entradas de blog, pero no un codigo real o imágenes originales con thumbnails. Así que decidí investigar el problema por mi cuenta. Actualmente llevo encontrada información escondida en páginas web del FBI, CIA, Skype, diversas paginas de la policía y por supuesto todo tipo de sitios de fotos amateur estilo Sexy-o-no. El foro está disponible aquí. Escribí aquí acerca de nuevas ideas, imágenes encontradas, preguntas técnicas y ese tipo de cosas…

EXIF, IPTC, XMP Software – Metadata Readers, Editors, Extraction Tools

Almost all digital cameras store extra information, called metadata, with your pictures. The extra information captured by your camera is called EXIF data, which stands for Exchangeable Image File Format. While most current photo manipulation software supports the reading of this information, there are many specialized tools for reading, editing, extracting and converting EXIF information.You can also store information in your pictures using other types of metadata. Two of the most commonly used formats of metadata for photos are: IPTC, the standard developed by the International Press Telecommunications Council; and XMP, the “Extensible Metadata Platform” developed by Adobe. The software listed here is designed for working with all types of metadata including EXIF, IPTC, and XMP.

BR’s EXIFextracter

BR’s EXIFextractor is a simple freeware program that will extract the EXIF meta information from all digital photos (JPEG files only) in a folder and saves the data in a CSV-file (Comma Separated Values). This file can be read by any program that is capable of reading CSV-files, for instance Microsoft Excel, Microsoft Access, PixFiler, and most other databases.


Protocolo NMEA – 183 / SiRF

13 Enero, 2008

Muchos de los receptores GPS actuales permiten seleccionar el protocolo de salida entre el tradicional NMEA-0183 y el nuevo protocolo SIRF. Ambos protocolos permiten transferir los datos recibidos por el receptor GPS a un determinado programa instalado en un ordenador o PDA. Algunos de estos datos son: posición, altitud, satélites en cobertura, intensidad de su señal, hora, fecha, etc.  Si ambos protocolos aparentemente hacen lo mismo, ¿Dónde está la diferencia?

El protocolo NMEA-183 (National Marine Electronics Association) es un protocolo estándar, prácticamente incorporado en todos los receptores GPS y admitido por la gran mayoría de los programas que permiten conexión a un GPS. Precisamente esta estandarización y su amplia difusión es la cualidad más destacable de este protocolo.

La mayor parte de los receptores envían de forma continua sentencias NMEA 0183, normalmente un grupo por segundo. Dichas sentencias, comienzan siempre por el signo “$” y están formadas por letras, números y signos o sea caracteres ASCII.  La velocidad típica de este protocolo es de 4800 baudios 8N1, aunque puede operar a otras velocidades.

Por otro lado, la empresa SiRF fundada por Kanwar Chadha, desarrolló un nuevo sistema más moderno de procesamiento de la señal de los satélites. El protocolo SiRF presenta una transferencia de datos entre el GPS y el ordenador más fluida, tiempos menores en la adquisición, mayor rapidez a la hora de calcular la posición y más precisión, además de permitir a los distintos programas un manejo más completo del receptor GPS; ya que admite el envió de comandos que permiten, por ejemplo, activar o desactivar el sistema WAAS/EGNOS, inicializar el receptor, ajustar una serie de parámetros del receptor, etc. Puede encontrar más información sobre el tema en http://www.gpspassion.com/fr/articles.asp?id=50.

La velocidad típica a la que suele operar el protocolo SiRF es de 57600 baudios 8N1, aunque se puede configurar cualquier otra velocidad. La transmisión de datos se realiza en formato binario.

Otra característica del SiRF es que en cada segundo se actualiza la señal de los satélites individualmente, esto puede ser útil para hacer un control preciso de la señal recibida de cada satélite en todo momento.

De todas formas tenga presente de que en la actualidad existen una gran mayoría de programas que no aceptan dicho protocolo, como por ejemplo el Route 66, OziExplorer, Autoroute, etc. Sin embargo no dudamos de que en un futuro inmediato aparezcan nuevos programas que aprovechen al máximo las posibilidades de este novedoso protocolo.

La elección de uno u otro protocolo, dependerá realmente del software que utilice. No obstante, hoy por hoy el protocolo NMEA es el más compatible con la mayoría de los programas y está especialmente recomendado cuando tenga mas de un programa instalado y alguno de ellos no soporte SiRF, ya que de lo contrario tendría que estar cambiando la configuración del GPS al cambiar de programa.

Para poder seleccionar la velocidad y el modo en aquellos GPS que lo permitan, como por ejemplo los receptores de SysOnchip o los HAICOM HI-302LP y HI-303MMF, existen varios programas tanto para PC como para PDA que permiten hacerlo. Algunos de estos programas son:

Para PC:

SirfDemo, un programa que distribuye la propia empresa que ha creado el SiRF. Puede descargarlo de aquí http://www.gpspassion.com/download/sirfdemo340.zip

Para PPC:
