The options are dynamically added, depending on the format. All settings are saved across sessions. See below for a detailed description.
Exports the page as a HTML page, that is preformatted text in a fixed spacing typewriter font. Zapzilla picks an encoding which can represent the page most efficiently, for example Greek: ISO-8859-7, other characters are encoded as Unicode references.
For those characters not representable even in Unicode, i. e. all sorts of graphics characters, you can enter a replacement. A single character (" " - space) stands for itself, alternatively you can enter the Unicode number in decimal ("32") or hexadecimal ("0x20") format.
HTML can preserve a number of text attributes: Underlined, bold, italic style, blinking, foreground and background colors. These are stored by embedding CSS information. You must enable Style Sheets in your browser to actually see color. Zapzilla creates anchors for URLs and e-mail adresses found in Teletext pages, page numbers are not linked.
The HTML file will include a title displaying the station name and page number. To concatenate HTML pages into a larger file the dialog offers an option to omit the page header.
Export the page as PPM image, in raw (P6) format.
The font used to render Teletext and Closed Caption pages attempts to mimic a real TV. One implication is that a real TV doubles the vertical resolution by overlaying the same image on both fields of the picture. The dialog includes the option to create a picture with correct aspect ratio, however this will duplicate every line of the image, doubling its size without adding any new information.
On a further note, a real TV has a pixel clock unlike computer monitors, creating rectangular instead of square pixels. In other words, the image looks slightly taller than it would on a TV.
Another method to grab the page in this format, you can select a region to be copied to the clipboard and paste the image into your favourite GNU image manipulation program.
This format contains the same information as PPM. Additionally transparency and overlay attributes are preserved and the file is much smaller. A title is included, displaying the station name and page number. The aspect ratio issue discussed in the PPM section applies here as well.
To preserve color and a few text styles you can enable the insertion of VT 100/200 control codes. Since terminals support only eight of the up to 4096 colors possible with Teletext Level 2.5 ("HiText"), they will be approximated.
As another method to grab the text of a page you can select a rectangular or wrapping region to be copied to the clipboard. However this mode supports ASCII only and color will be lost.
VTX stores pages in raw Teletext Level 1.0 format. This will impair Greek, Cyrillic, Hebrew and Arabic pages, strip off any national characters transmitted at Level 1.5 and the Level 2.5/3.5 additional colors, styles and graphics. The Zapping hyperlinks, i. e. page numbers, URLs and e-mail addresses, are not preserved.
