While working on a tool that allows to exchange images of several third-party applications and thus creating individual "skins" for those applications, I have stumbled across a jpg-format about which I cannot seem to find any decent informations.

When looking at it in a hex-editor, it starts with the tag "CF10". Searching the internet has only provided a tool that is able to handle these kind of files, without any additional informations.

Does anyone have any further informations about this type of jpg-format?

file(1)应该给你一些有用的信息。您还可以使用 ImageMagick 的identify(1)程序（可以选择使用该-verbose选项）来获取有关该文件的更多详细信息。请参阅该页面上的示例，以很好地了解它提供的信息。

您还可以尝试查看Droid识别工具对该文件的说明。

CF stands for "Compression Factor". CF-10 means factor ten, and I don't think it's different from any "standard" jpeg.

DROID 将其称为“JTIP（JPEG 平铺图像金字塔）”。来自http://www.bcr.org/cdp/digitaltb/digital_imaging/formats.html的一些信息：

JTIP（JPEG 平铺图像金字塔）类似于 GridPrix。它提供多层越来越高的分辨率。每一层进一步分为瓦片。用户可以放大这些图块，或请求更高分辨率的相应图块。
