This patch takes the cylinder pressures of CCR dives and prints them in a non-overlapping way. Remaining issue: When the dive profile is made taller by dragging the window or the appropriate slider far down the screen, the labels move further apart; similarly, when the profle is made flat/shallow by dragging the window edge or appropriate slider up, the labels get close to each other and start to overlap. There are quite a few lines of additional code going into the patch. This is primarily because separate provisions for when po2 > p(diluent) or vice versa. In addition, I could not determine the size of the text characters which would allow much more precise placement of text. This is because the .scale member of the text is private and not available in the methods involved in printing the labels. However, the height of the vertical scale of the cylinder pressure graph can be determined [e.g. vAxis->maximum()]. This helped a lot to get the positioning of the text more or less correct. While the results of the patch is not perfect, It contributes significantly to make the profiles of Poseidon dives more readable.

This is the README file for Subsurface 4.4 Beta 1 Please check the ReleaseNotes.txt for details about new features and changes since Subsurface 4.3 Subsurface can be found at http://subsurface-divelog.org Our user forum is at http://subsurface-divelog.org/user-forum/ We also try to respond to questions in the ScubaBoard.com dive software forum at http://www.scubaboard.com/forums/dive-software/ Report bugs and issues at http://trac.subsurface-divelog.org License: GPLv2 You can get the sources to the latest development version from the git repository: git clone git://git.subsurface-divelog.org/subsurface.git . You can also browse the sources via gitweb at the same site. If you want the latest release (instead of the bleeding edge development version) you can either get this via git or the release tar ball. After cloning run the following command: git checkout v4.3 (or whatever the last release is) or download a tar ball from: http://subsurface-divelog.org/downloads/Subsurface-4.3.tgz Detailed build instructions can be found in the INSTALL file. Basic Usage: ============ Install and start from the desktop, or you can run it locally from the build directory: On Linux: $ ./subsurface On Mac: $ open Subsurface.app Native builds on Windows are not really supported (the official Windows installers are both cross-built on Linux). You can give a data file as command line argument, or (once you have set this up in the Preferences) Subsurface picks a default file for you when started from the desktop or without an argument. If you have a dive computer supported by libdivecomputer, you can just select "Import from Divecomputer" from the "Import" menu, select which dive computer you have (and where it is connected if you need to), and hit "OK". The latest list of supported dive computers can be found in the file SupportedDivecomputers.txt. Much more detailed end user instructions can be found from inside Subsurface by selecting Help (typically F1). When building from source this is also available as Documentation/user-manual.html. The documentation for the latest release is also available on-line http://subsurface-divelog.org/documentation/ Contributing: ============= There is a mailing list for developers: subsurface@subsurface-divelog.org Go to http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface to subscribe. If you want to contribute code, please either send signed-off patches or a pull request with signed-off commits. If you don't sign off on them, we will not accept them. This means adding a line that says "Signed-off-by: Name <email>" at the end of each commit, indicating that you wrote the code and have the right to pass it on as an open source patch. See: http://developercertificate.org/ Also, please write good git commit messages. A good commit message looks like this: Header line: explain the commit in one line (use the imperative) Body of commit message is a few lines of text, explaining things in more detail, possibly giving some background about the issue being fixed, etc etc. The body of the commit message can be several paragraphs, and please do proper word-wrap and keep columns shorter than about 74 characters or so. That way "git log" will show things nicely even when it's indented. Make sure you explain your solution and why you're doing what you're doing, as opposed to describing what you're doing. Reviewers and your future self can read the patch, but might not understand why a particular solution was implemented. Reported-by: whoever-reported-it Signed-off-by: Your Name <youremail@yourhost.com> where that header line really should be meaningful, and really should be just one line. That header line is what is shown by tools like gitk and shortlog, and should summarize the change in one readable line of text, independently of the longer explanation. Please use verbs in the imperative in the commit message, as in "Fix bug that...", "Add file/feature ...", or "Make Subsurface..." A bit of Subsurface history: ============================ In fall of 2011, when a forced lull in kernel development gave him an opportunity to start on a new endeavor, Linus Torvalds decided to tackle his frustration with the lack of decent divelog software on Linux. Subsurface is the result of the work of him and a team of developers since then. It now supports Linux, Windows and MacOS and allows data import from a large number of dive computers and several existing divelog programs. It provides advanced visualization of the key information provided by a modern dive computer and allows the user to track a wide variety of data about their diving. In fall of 2012 Dirk Hohndel took over as maintainer of Subsurface.
