Here is one that you haven't mentioned: C) Use the status bar for displaying and modifying the position and size of the selection. Instead of displaying a simple text label with the size of the selected area, the status bar could automatically replace this text by two (width, height) or four (x, y, width, height) entry boxes when the user starts selecting something. The value in these boxes would change while the user is dragging the rectangle and modifying the selection interactively but it would also be possible to edit the values directly in the status bar. Note that these entry boxes would only need to be there while a selection is being modified (i.e., after the first click and drag). They do not have to be there all the time while a selection tool is active, so the status bar can still be used to display some other useful information as text when the user is not currently editing a selection. This also means that the box and drop-down list with the zoom ratios can be temporarily replaced in order to gain more space in the status bar for these new entry boxes. In addition, a small icon or expander button could be added to the status bar while such a tool is in use; clicking it would pop up a dialog box containing more options. There are always more options that could fit in the status bar, such as constraining the selection to a fixed aspect ratio, etc. A little button in a corner of the status bar would provide a convenient way to display this dialog with advanced options only when needed. > Personally, of the two, I favor A, for a couple of reasons. If C is not accepted, then I favor B. Although you are right that the Tool Options were not intended to be used for active control of a tool, I think that the disadvantages of having a window that gets in the way outweight its advantages. By the way, the status bar is part of the image window so unlike the additional dialog or even the Tool Options, it will never get in the way of the interactive selection. I think that option C would be the most user-friendly: the important information is visible without getting in the way, the interface is easy to understand, and there is no need to remember special key combinations for showing/hiding the dialog with extra options. The disadvantages of option C are that it would require more coding due to the modifications of the status bar and it would not be possible to display all entry boxes if the image window is too narrow. On the other hand, it would be easy for the user to make the window wider whenever necessary. -Raphaël P.S.: I hope to see some of you at FOSDEM on Saturday and Sunday in Brussels.

[Gimp-developer] Re: Rect tool
Can I propose 2 more options 1) Pop up dialogue is activated by hotkey (and perhaps on screen widget) - this approach is used quite successfully in several 3D applications. Usual Tab or N "numeric" is used. 2) Draw options on canvas - perhaps with hotkey/widget to show hide these additional options This has the additional advantage of not obscuring the picture while adding numerical input. I can do some mockups if that makes any of this clearer. -- Oh, get ahold of yourself.

Here are some results for you: Dual 2.5ghz g5 mac, mac os x 10.3.8 CVS gimp Changelog revision 1.10539 Linear Gradient blend on a 3000x3000 pixel image (Dithering on) 1 Processor: 7.98 seconds1x 2 processors: 5.20 seconds1.5x 3 processors: 5.23 seconds1.5x Linear Gradient blend on a 3000x3000 pixel image (Dithering OFF) 1 processor: 3.89 seconds1x 2 processors: 2.37 seconds1.7x 3 processors 2.40 seconds1.7x Clearly the gradient code could use some tuning. A linear blend shouldn't take much more than 1/2 a second even with dithering. The reason why the dithering case gets less of a speedup is because the threads are fighting over the GRand state. Each thread needs to have it's own GRand state. It looks like the threads are also fighting over gradient->last_visited. My guess is that fixing this will get us much closer to the ideal 2x speed up. I don't see myself hacking on the gradient code in the near future so anyone else should feel free...

Re: [Gimp-developer] choosing default file open handler with multiple handlers
Answering myself, just in case someone in the future needs the answer. Plugins are sorted alphabetically by "label" (7'th argument to gimp_install_procedure), which is the same as "File Type" (i.e. the name you see when you open the "Select File Type" expander in the open image dialog. So, you can select the default by selecting the appropriate label for each plugin. -Joseph Pepster wrote: Hi, When there are several plugins registering handlers for the same file extension, what/who exactly determines who ends up as the default handler?

Tool Options would be more consistent than the status bar, as is evidenced by the type of work required to modify the status bar. Most arguments for C are also arguments for B. D) If you want a button like option C to activate a dialog, it could go in the Tool Options instead of the status bar. This is preferable to A and C, but I prefer B over all. If you must hide some options you can make them collapsable, but I advise against having these options collapsed by default. I vote for B, D, C (in that order). _-T ___ Speed up your surfing with Juno SpeedBand. Now includes pop-up blocker!
