Introduction

This page intends to provide guidance to translators of the Hugin project. Some terminology is very specific or used in a specific way in hugin, making it hard to find a close translation that fits the context of hugin in another language than English.

Getting Started on translations

Each language has a *.po file containing all the translated strings. Those *.po files use the ISO 639-1 naming convention (like "fr.po" for French, "ja.po" for Japanese, ...). If no translation for your language exist, you'll have to create one using that naming convention or ask the developers list for assistance.

In general, you need the latest *.po files (or at least the one for the language you want to modify). You can download the current translation file for you language in the SVN repository. If there is no *.po file for your language, you can download the hugin.pot file.

To edit the *.po or *.pot files, use poedit (it is a cross-platform PO files editor which runs on Mac OS X, Unix and Windows) or kbabel (it runs on any KDE platform). Note that you don't have to translate everything if you don't have time or knowledge to do it all. Also check below for things that shouldn't be translated (like software names) or for some explanations on specific words.

NB: When using poedit, editing comments directly in the right pane doesn't work, the text isn't saved into the .po file. To edit comments, use the "edit comment" dialogue from the menu.

Submit your edited translation via hugin's patches tracker on sourceforge. Select the category "translation" and the group "hugin".

Use your new translation file

poedit updates your PO file and creates a MO file for your language. You can rename your MO file into hugin.mo and replace the hugin.mo file from your current installation (don't forget to make a backup of the original MO file, just in case).

- If you use Windows, the MO file is under your hugin directory, in share\locale\XX\LC_MESSAGES\hugin.mo, where XX is your language.

- If you use Linux, the MO file is under /usr/local/share/locale/XX/LC_MESSAGES/hugin.mo

If you want to can also rebuild hugin (doesn't have to be a heavy job when you only changed the .po file, the process only updates that part).

Translation guide for specific terms

Note to translators, please add your language variant to the term on a new line in the same format as NL=
Also add your own difficult terms that are not mentioned here.

Note to developers, please check and enhance the meanings of these terms if they are unclear or incorrect.

Custom parameters: Meaning=parameters other than standard (+context???); NL=aangepaste parameters

bundle: Meaning=A technique for distributing OS X software as a single file.; NL=bundle (bundel?)

bundled version: Meaning=? Any packaged software will contain multiple files, these files are said to be 'bundled' (not just OS X); NL=ingebouwde versie (gebundelde versie?)

image: Meaning= photo, scan, ....; ET=pilt; NL=afbeelding

Stitcher (the tab): Meaning= Where the actual combining of the images is done; ET=Ühendaja; NL=Samenvoegen (alt: Combineren, Naaien?)

grayscale: Meaning=monochrome colourspace. Typically grayscale images can have many shades of gray as well as black and white.; ET=halltoonid; NL=grijsschaal (kan beter!)

pyramid image: Meaning=This is the practice of creating a stack of successively smaller versions of an image, useful for many image manipulation tasks.; NL=piramidale afbeelding

mapping: Meaning=render and distort an image to a different projection?; NL=translatie, afbeelding, vervorming, projectie?

control points: Meaning=corresponding areas in two images (or the same image for horizontal and vertical control points); ET=juhtpunktid; NL=ijkpunten (was controle punten), IJkpunten bij hoofdletters

Druid: Meaning=wizard for ease of use, alternative names: Assistant, workflow guide, etc.; NL=Druide (kan beter?)

Cropped (images): Meaning=image cut smaller than the original size; Discussion=Should this be translated? Like Blend, this is jargon, may be clearer when untranslated?; ET=kärbitud (pildid); NL=uitgesneden (afbeeldingen)

Crop factor: Meaning=The physical size of a CCD sensor relative to a 35mm frame.

Exposure blending (or Exposure fusion): Meaning=Taking a bracketed photo stack and picking the best bits to create a new image. Hugin tries to use the phrase 'Exposure fusion' rather than 'blending' as the tool for this is enfuse.; NL=Blend van belichtingen?

Seam blending: Meaning=Taking two or more partially overlapping photos and blending then with a seam down the middle of the overlap. The tool typically used for this is enblend

Photometric Optimisation: Meaning=Optimisation of non-mapping image parameters, such as 'Camera response', Vignetting and Exposure.; ET=fotomeetriline optimeerimine; NL=fotometrische optimalisatie

Photometric Alignment: Meaning=Determining relative exposure, camera response and vignetting; ET=fotomeetriline joondamine; NL=fotometrische uitlijning (beter?: fotometrische afstemming)

Low Dynamic Range (LDR): Meaning=Luminance values are within a small numeric range (typically 8-bit or 16bit integer with a non-linear response curve).; NL=Laag Dynamisch Bereik (LDR)

High Dynamic Range (HDR): Meaning=Luminance values are within a large numeric range (typically floating point with a linear response); NL=Hoog Dynamisch Bereik (HDR)

Anchor: Meaning=Reference; NL=referentie (was anker)

Num. Transf.: Meaning=Numerical Transform. Rotation of panorama roll, pitch and yaw by manually entering numbers.; NL=Num. Transf.

Field of View: Meaning=Horizontal Angle of view; ET=vaateväli; NL=beeldhoek

flatfield: Meaning=An astronomical technique, using a photo taken with the lens covered or of an even white surface to calibrate normal photos; NL=flatfield (astrofoto jargon, ook in NL gebruikt)

flatfile: Meaning=?; NL=?

Aligning versus Finding control points: Problem= they appear to be similar or the same, can they be interchanged?

Vertical or Horizontal guide: Meaning=Horizontal or Vertical "control points"; NL=h/v hulp (suggestie: ijklijnen)?

Estimate (position, FoV, etc.): Meaning=? in my book, estimate means an educated guess. I get the impression that a more exact term is intended for hugin. Where can this term be replaced with "calculate" or "determine"?; ET=määratlema; NL=bepalen (eng:determine), bereken (eng:calculate) alternative suggestion: Schatten (eng:estimate)

Camera response (C. r. curve): Meaning=it corresponds with photo-electrical transfer function, and I am not sure can I translate it to "opto-electic curve of camera" in my language, because stright tranlation of "camera response" statement sounds trivial and not clear.; PL=krzywa optoelektryczna aparatu?

Do not translate:

Nona (program name)
Enblend (program name)
Autopano (program name)
Autopano-SIFT (program name)
PTStitcher (program name)
Deflate (zip method)
JPEG (file type)
EXR (HDR file type)

Technical translation issues

Some strings don't appear to be translated, they are apparently generated by the GUI toolkit or the operating system. Most likely they will be in the same language as hugin, because very few people, other than translators, start a program with a specific language other than that of the environment.

If you find a source term that isn't correct, spelling or meaning, probably best to bring it up with Pablo d'Angelo or on the hugin mailinglist: [1]

List of source string problems

approximation of values beetwen source pixels

between

calculate highest sensible width. (uses every image pixel)

I can translate this literally, but is this even helpful in English? (this is a tooltip for the size calc button in the Stitcher tab)

Tips and Tricks

Running hugin in a specific language

If you want to run hugin in another language than the default, use the following command (Linux with UTF8):

$ LANG=nl_NL.utf8 hugin

This will start hugin in dutch. Other languages have different names of course, try looking in /usr/share/i18n/locales/.

Developer info

Adding new strings

After adding new strings, translators need to find them in the .pot and .po files otherwise they won't get translated.

Hugin has a script to extract the messages from both the .xrc files and the .cpp source code and insert them into the hugin.pot and .po files. New strings are added and unused strings are marked as obsolete:

 svn up
 cd src/translations
 ./extract-messages.sh
 svn diff
 svn ci

Applying a contributed .po file

You could just overwrite the original and commit, but this assumes the file is correctly formatted and hasn't lost any strings. Better to use msgmerge to merge the contributed .po file with the existing:

 msgmerge -o zh_CN.merged.po /tmp/zh_CN.contributed.po src/translations/zh_CN.po
 mv zh_CN.merged.po src/translations/zh_CN.po
 svn diff
 svn ci
