Some people may want to fax a html document in their application. First it is necessary to convert the html document into image that the fax driver can understand. Fax machines typically support TIFF format which supports multiple encoding scheme. Html Snapshot has full support for TIFF encoding. It supports LZW, CCITT3, CCITT4 and RLE (Pack bits) encoding. So you can easily convert a html document into fax compatible TIFF file with Html Snapshot.
If you are using Windows Faxing Service to send a fax, remember that it has some special requirements on the TIFF file.
The fax service will accept a TIFF file for transmission if it has the following properties:
- Compression is either 1 (no compression) or 4 (CCITT Group 4 fax encoding)
- Image width is 1728 pixels
- X-Resolution < = 204dpi and Y-Resolution <= 200dpi
- All the pages have the same Y-resolution
There is a detailed html to TIFF demo in the trial version of html snapshot. you can find it under demo\vbscript\tifftest.vbs. Feel free to drop us an email if you have other questions.
