<Save>/HTML with many small tiles using data:-urls/html
Saves the image as many small tiles using data:-urls.
[PF_SPINNER, "tile_x", "Tile width", 32, [0, 8192, 1, 10]], [PF_SPINNER, "tile_y", "Tile height", 32, [0, 8192, 1, 10]], [PF_RADIO, "filetype", "Underlying file type", 0, [GIF => 0, JFIF => 1, PNG => 2]],
DATAURL FILE FORMAT
After reading rfc2397, which describes the
data: url scheme, I got the idea of embedding a normal image into a html document, without resorting to external files.
This is accomplished by embedding small tiles of the image directly into data:-urls. Since attribute values are by default limited to 1024 bytes this limits the size of a tile to approximately 34x34 pixels (gif compression).
However, since rfc2397 is only a proposed standard, you might want to use much larger tile sizes (upto the image size), since most browsers generally do not care for the url length.

I'm thinking images only... <schmorp> tommer: if you think text then encoding=gzip makes sense <schmorp> tommer: I also haven'T tried wether these urls work in frameset and normal anchor elements <schmorp> but actually, the colorhtml filter is much more portable <yosh> yeah, it just takes aching long to render and scroll <Tommer> schmorp: how about <img lowsrc="data:image/gif;base64, ...
