When I try to save a roi in imagej using the code below, a window prompts to save the roi. However, I want to save the roi programmatically so that I can do it for several different files. How can I avoid the prompt window and how can give each roi a specific name (the whole file is saved with the name RoiSet which contain several roi that each should have a different name I choose)?
rm.runCommand("Save", IJ.getDirectory(r"path to my folder") + "RoiSet.zip")
The issue is that IJ.getDirectory(String) returns null, so your path becomes nullRoiSet.zip, which ImageJ thinks is not a valid path, and therefore it prompts with a dialog box.
You do not need the IJ.getDirectory call here; just pass r"path to my folder\RoiSet.zip" directly and it should work without popping any dialogs.
It looks like you are not using the macro language, which might make things a tad more difficult, but I'm not an expert by any means, so take that assumption with a grain of salt. If you do decide to switch and use the macro language, you can simply wrap your code in the batch mode function like so:
setBatchMode(true);
example code here;
setBatchMode(false);
As for saving, the macro language uses the saveAs() function, which takes file type and save path + title of the file as arguments. If you want more info about, or help writing in, the macro language, let me know and we can likely put something together rather quickly.

I wart to create a web app where a user enters certain data via a form and then receives a custom rendered image. The image is from a smart object in a psd. It's kind of like a mock-up which definitely requires needs some photoshop filters to be properly rendered.
This should all happen in real time and should be doable from my understanding since the rendering of a single images doesn't need much computing power
I've done some research and haven't really found a solution the matches my problem. Is it necessary to run Photoshop on a server and then remotely run a photoshop script and then upload the generated image somewhere else?
I've used The After Effects Plugin Template by DataClay in the past which offers similar functionality but for video.
Looking forward to hearing your ideas.
Thanks
You can use the Dataclay plugin to handle still image exports out of After Effects. Make a single-frame duration composition in After Effects and rig the layers with the Templater plugin. Then use the PNG Sequence output module to render out a single frame.
From Dataclay's forums:
Exporting
A few extra steps are required to correctly render a project file as a PNG sequence using Templater. By default, a file rendered as a PNG sequence will have the frame number appended to the end of the file name, i.e.:
filename.png00000, filename.png00001, filename.png00002, etc.
In order to designate where in the filename the frame number should be added, we’ll need to use the output column. First, add a column named output to your data source. Next, add a filename with a set of brackets with five # signs to designate where the frame numbering should be added. For example:
filename[#####] would result in filename00001.png
or
[#####]filename would result in 00001filename.png
I am trying to integrate the plugin, bUnwarpJ into an ImageJ macro I have been writing. The aim is to call this plugin, allow the user to define the parameters and run it.
This plugin has an option to save the user defined parameters, i.e., "save landmarks". I would like this to be executed as well by calling: call("bunwarpj.bUnwarpJ_.saveLandmarks", output folder) from within my plugin.
Currently, the code is:
run("bUnwarpJ");
call("bunwarpj.bUnwarpJ_.saveLandmarks", output folder);
The problem is once bUnwarpJ is completed, you cannot call 'save landmarks' method, and will lose the user input data as well. How would you solve this?
One idea was to have a pop up window (before the run command) which will NOT pause the user interaction, and when the user completes defining landmarks, they can then click OK on this window which executes call(), thereby saving the landmarks while bUnwarpJ is running. The problem I had was most of popup windows will pause the rest of the code..It would ideally be like:
#command for popup window here
run("bUnwarpJ"); #when user is finished, they click Ok on the box above
#which executes: call("bunwarpj.bUnwarpJ_.saveLandmarks", output folder);
Any help is appreciated. Thanks!
Is the user defining landmarks by creating an ROI or something else that might require them to actually interact with an image? If not, and/or those landmark values can be generated ahead of time (using a single image as a template for your batch), you might consider just adding a user interface/dialog box that requests the landmark values and then saves them as a set of variables, or an array. Let me know if that sounds like it might be on the right track and I can do my best to help you set that up.
Using the initial dialog box would definitely be the simplest method to get the input parameters. If for some reason this doesn't work, you might consider putting in a line like:
run("bUnwarpJ");
waitForUser("Input Your Parameters");
I haven't used UnwarpJ, but the waitForUser command should allow the macro to pause for the manual input if the user is meant to do steps other than just parameter inputs. Otherwise, ejkiely's suggestion will be the fastest solution.
I want to make a small "library" to be used by my future maxima scripts, but I am not quite sure on how to proceed (I use wxMaxima). Maxima's documentation covers the save(), load() and loadFile() functions, yet does not provide examples. Therefore, I am not sure whether I am using the proper/best way or not. My current solution, which is based on this post, stores my library in the *.lisp format.
As a simple example, let's say that my library defines the cosSin(x) function. I open a new session and define this function as
(%i0) cosSin(x) := cos(x) * sin(x);
I then save it to a lisp file located in the /tmp/ directory.
(%i1) save("/tmp/lib.lisp");
I then open a new instance of maxima and load the library
(%i0) loadfile("/tmp/lib.lisp");
The cosSin(x) is now defined and can be called
(%i1) cosSin(%pi/4)
(%o1) 1/2
However, I noticed that a substantial number of the libraries shipped with maxima are of *.mac format: the /usr/share/maxima/5.37.2/share/ directory contains 428 *.mac files and 516 *.lisp files. Is it a better format? How would I generate such files?
More generally, what are the different ways a library can be saved and loaded? What is the recommended approach?
Usually people put the functions they need in a file name something.mac and then load("something.mac"); loads the functions into Maxima.
A file can contain any number of functions. A file can load other files, so if you have somethingA.mac and somethingB.mac, then you can have another file that just says load("somethingA.mac"); load("somethingB.mac");.
One can also create Lisp files and load them too, but it is not required to write functions in Lisp.
Unless you are specifically interested in writing Lisp functions, my advice is to write your functions in the Maxima language and put them in a file, using an ordinary text editor. Also, I recommend that you don't use save to save the functions to a file as Lisp code; just type the functions into a file, as Maxima code, with a plain text editor.
Take a look at the files in share to get a feeling for how other people have gone about it. I am looking right now at share/contrib/ggf.mac and I see it has a lengthy comment header describing its purpose -- such comments are always a good idea.
For principiants, like me,
Menu Edit:configure:Startup commands
Copy all the functions you have verified in the first box (this will write your wxmaxima-init.mac in the location indicated below)
Restart Wxmaxima.
Now you can access the functions whitout any load() command
Well, to start with, I don't know much about Latex. I am failing to include a picture in to the document using "Moderncv Casual". A lot of the CV's and cover letter's template using:
\photo[64pt][0.4pt]{filename}
What's the deal with this? Is it not just to type the pictures's filename, compile, and the picture should be added to the document?
That's exactly it. The \photo macro is set up in such a way that it stores your input and makes it part of the CV title (set with \makecvtitle).
The reasoning behind this is to provide the end-user with a generic command to would capture a picture. However, depending on the template used, this picture may appear on the left/right/middle (or wherever). The generic input abstracts this placement from the rest of the code.
Specific to the command \photo; it is defined inside the class moderncv.cls file as:
\NewDocumentCommand{\photo}{O{64pt}O{0.4pt}m}
{\def\#photowidth{#1}\def\#photoframewidth{#2}\def\#photo{#3}}
An input like
\photo[64pt][0.4pt]{filename}
defines the photo to be kept in \#photo - it references the image file filename (with an image extension) - to have a width of 64pt (stored in \#photowidth) and frame width 0.4pt (stored in \#photoframewidth).
I have an application and posted to Cydia recently. It has been cracked by someone else and posted it in torrent sites. I have a binary checksum verification mechanism inside and they were able to create a new checksum file based on the changes they have made to the binary. They have edited two functions and decompiled it and posted it to torrents.
I saw that it's possible to see the actual implementation of functions and classes. But in order to edit the functions they have to find the address of that function and edit it via HEX EDITOR. I don’t want to make it "unhackable", but I really want to find out how they hack.
How can I edit a function in an iOS binary and re-compile it? For example I have a following method in one of my classes.
- (id) getSomething {
return #"Something";
}
I want to edit the return value of this function. Is that possible?
Usually, you don't "re-compile" it. Just feed the file to IDA, look for strings, function calls or whatever you are looking for and then use a hex editor or similar to edit the file on assembly level. In most cases it's enough to simply change a conditional jump into an unconditional jump or a nop (no operation). If you want to change return values, you have to put a little more effort into it, but in my experience you either edit the char sequence right inside the binary file, if it's specified as a constant or initial value - or you just write a completely new function and "copy" the assembler code of it into the original file. You just have to make sure your new function does not take more space than the original - or everything's getting a lot more complex.
I hope that's what you were asking for, otherwise just tell us which app you are talking about and we can look deeper into it :)
