You might have to upgrade to something more recent, like octave 3.5.5 or greater. (The latest stable Octave is 3.6.2.) Along with that, an upgrade in gnuplot would be good too.

Hello, I have a question regarding symbols in plotting. I wonder about the very basic one, which is circle 'o'. When I use this for plotting [plot(x,y,'o')], instead of having circle, I get triangle shape with a dot in the middle! What should I do to solve this tiny/strange problem? Thanks in advance, Sue |

Well, the really really non recommended way would be to just find where your .m files of image package version 1.0.15 are and replace all of them (except bwdist.m) with the ones from the image 2.0.0 version. This will cover most of the changes on the new version. The changes that you won't see should be the new function bwlabeln and a bug in bwfill (which you can workaround by always use logical(bwlabel(x)) instead). It should work but is not pretty at all.

The physicalconstants package is not necessary at all. It's not a dependency of anything and if you look at it (just type "news physicalconstants" at the octave prompt) you will see why it exists even though it implements no function at all. You would do better removing it and forget it existed. > Trying to install image-2.0.0.tar.gz gives afore mentioned error message. > > File "lo-cutils.h" (mentioned in the error message): >> >> line 50> OCTAVE_API pid_t >> line 51> octave_waitpid (pid_t pid, int *status, int options); This problem seems to be specific to windows and reside somewhere in octave core. There are indeed a lot of changes for the new version of the image package but if you may have to wait until one of the devs involved with windows prepare a new release of this package. > I thought that perhaps the updated packages must be "activated" and loaded > them (pkg load general, pkg load signal, pkg load windows), but the error > messages remains the same. No. Other packages are not necessary for the installation, no need to actually load them before. Carnë |

My configuration: Windows XP SP3 (German) Octave installed in: D:\Portables\Octave3.6.2_gcc4.6.2 I have installed both 7z-archives from http://sourceforge.net/projects/octave/files/Octave%20Windows%20binaries/Octave%203.6.2%20for%20Windows%20MinGW%20installer/ according to the "Manual installation instructions". Octave seems to work ok. Now I wanted to update the image package to the new version 2. According to the dependencies mentioned, I installed the packages general-1.3.2.tar.gz and signal-1.2.0.tar.gz, and also miscellaneous-1.2.0.tar.gz and physicalconstants-1.0.0.tar.gz - all without any error. Trying to install image-2.0.0.tar.gz gives afore mentioned error message. File "lo-cutils.h" (mentioned in the error message): > line 50> OCTAVE_API pid_t > line 51> octave_waitpid (pid_t pid, int *status, int options); I thought that perhaps the updated packages must be "activated" and loaded them (pkg load general, pkg load signal, pkg load windows), but the error messages remains the same. I also attach a screenshot of a directory including the directory tree in the TEMP folder. This directory seems to contain files that are mentioned in the error message. Some files have been left over from the installations. The last attempt of installing image-2.0.0.tar.gz gave directory "oct-14". Being a very new user of Octave, I could have done something wrong, but I rather think that there is some bug. How can I help resolving this problem? I have basic knowledge of programming and PCs. I am a very new user of Octave, I installed it just one week ago. (I am currently attending a lecture about image processing, and I would like to use Octave for this purpose. Therefore the image package is important for me.) Thank you for your work on this great project! Sorry for my bad English, it is not my native language. Best wishes, Gerald |

Just curious why you chose Qt initially. Would you like the Qt interface on your system? One thing we are attempting at the moment is using Qt toolkit via gnuplot. In linux, it works.

Just curious why you chose Qt initially. Would you like the Qt interface on your system? One thing we are attempting at the moment is using Qt toolkit via gnuplot. In linux, it works.

Hello, Sorry for the mistake. I've just started working with octave. First, I installed octave with the default parameters : "Toolkit = qt". I have just uninstalled and reinstalled it but this time I chose "Gnuplot" as graphics toolkit and the problem is solved. Thanks a lot.

You run the qthandles toolkit which has no implementation for ginput, switch to one of the others and try with that close all graphics_toolkit fltk for example at the octave prompt (you may need to close all graphics before with the close all). |

Too precise. :-) > Just to be more precise, I installed this version of octave "Octave 3.6.2 > for Windows Microsoft Visual Studio". Octave uses a graphics engine to draw the figures. What we mean by "engine" at this level is a different program that draws the lines, fonts, etc. for display on the screen. "gnuplot" means that Octave is using gnuplot plotting program to create figures. "fltk" means that Octave is using a drawing library. "qt" (what you are seeing) would mean that some form of the Qt user-interface tools is being used. Please describe what your window looks like that contains the grayscale image created by your "image" command. Are there some icons? If so what do those icons look like? Dan |

Hello Dan, Thanks for reply me. My graphics type is a: "Mobile Intel(R) 965 Express Chipset Family". Just to be more precise, I installed this version of octave "Octave 3.6.2 for Windows Microsoft Visual Studio".

Hi Héctor, I'm not exactly sure because this works on a fairly recent development version on my linux system. I am using gnuplot for the graphics and get a toolkit description of octave:3> toolkit = (get (gcf, "__graphics_toolkit__")) toolkit = gnuplot for both command line interface and GUI. From the error message you've shown, you should get a toolkit description of "qt". I've searched the script codes in the source tree and don't immediately see how "qt" could end up in your figure structure. What graphics are you using on your Windows XP system? Is it gnuplot, fltk, something else? (I ask because I haven't much experience with how Octave behaves under Windows.) If you don't know that, please describe what the window containing the image of random grey pixels looks like. Dan |

Hello, I've installed octave 3.6.2 on windows XP. And I try to use the function "ginput" : imshow(rand(100)) [x,y]=ginput(1) But I get this error: error: feval: function '__qt_ginput__' no found error: called from: error: <>\m\plot\ginput.m at line 41, column 21 Does anyone have an idea?
