|
| 49 | Libpsiconv consists of two parts. The parser reads the Psion file into its |
|
|
| 50 | internal data structures. The generator reads these data structures and |
|
|
| 51 | generates an output file in some other format. Libpsiconv is written to make |
|
|
| 52 | it easy to add generators, without having to modify the parser side. |
|
|
| 53 | Actually, it is a lot easier to write a generator than to modify the parser! |

|
| 61 | The current HTML target is not very ideal. HTML is just not made to |
|
|
| 62 | represent detailed layout considerations: it is a document description |
|
|
| 63 | language. Still, the output is quite readable already. Of course, headers |
|
|
| 64 | and footers are not displayed, because there is no notion of pages in |
|
|
| 65 | HTML. Tabs are also difficult; they are not supported yet. This can be |
|
|
| 66 | solved using tables, but it is quite hard to do it correctly. Some other |
|
|
| 67 | things are just approximated too. |
|
|
| 68 | |
|
|
| 69 | The HTML4 target uses style sheets. You need a not-too-old browser for |
|
|
| 70 | this to display correctly. Generally, the output of this generator is |
|
|
| 71 | of higher quality than the normal HTML generator's. |
|

|
|
| 73 | A plain TEXT target just grabs all text, without any futher conversions. |
|
|
| 74 | |
|
|
| 75 | I would very much like to add other targets, like (La)TeX, RTF (Rich Text |
|
|
| 76 | Format) and XML (for AbiWord). If other people want to work on this, please |
|
|
| 77 | let me know! Of course, you could also write your own conversion applications |
|

| 78 | just using my data format description. Native import/export filters for |
