I am using 'tess4j' api to get the text from a .jpg image.
The 'TessData' folder is packaged in the jar files. I want to include custom fonts and create my own 'TessData' folder, is there a way we can give 'TessData' location during run time.
I used the below method and it didn't pick up the TessData from custom location.
TessAPI1.TessBaseAPIInit3(handle, "C:\1. tesseract folder\bodoni mt\TrainData", lang);
Please let me know if we can do so.
That does not look like a valid string. Anyway, if tessdata is inside a JAR file, you'll need to extract it and specify the location in the Init method.

With file_picker, I can't get file's real path or URI from FilePicker.platform.pickFiles(). It only returned something like this
/data/user/0/my_app_dir/cache/file_picker/file
and logged this
I/FilePickerUtils(27005): Caching from URI: content://com.android.providers.media.documents/document/video%3A1519
D/FilePickerUtils(27005): File loaded and cached
at:/data/user/0/my_app_dir/cache/file_picker/file
D/FilePickerDelegate(27005): File path:[com.mr.flutter.plugin.filepicker.FileInfo#705d9ef]
That's not what I want. I just want the real original absolute file path, the file information, regardless of what I'll going to do with the file. So I'm looking for a package that do that or the solution how to manually pick file and get the file path like I could do natively. Thank you in advance.
It's not impossible with native code. It's just package publisher who made it unavailable using it. Follow this to implement file path picker on native code. It works for me.
I want to get gallery folder path.
I tried to use multiple libraries [path_provider, storage_path, image_save, multi_image_picker ...] to get the gallery folder path, but none of the libraries got the gallery folder path.
See, I don't find any great thing to save your file to your gallery, what I did found is to how to get your things done.
My solution will give you some things like
Save a file visible to the user
Check whether the file exists or not
Saving the file:
For saving the file we can rely on the package downloads_path_provider.
Look at this answer for using this package precisely
Flutter save file visible to the user - StackOverFlow would help you to know how he is using path_provider package to save his files.
Check whether the file exists or not
To do this, you can use this code inside your code, where you are trying to save the file, form the above answer.
Important: You will get the path of the file where you are storing the file, just pass the path in the below code
import 'dart:io' as io;
// for a file
bool exists = io.File(path).exists();
// for a directory
bool exists = io.Directory(path).exists();
if(exists) // do your operation
else // do your else operation
I am able to produce this much content for your problem. Any feedback are welcomed.
In my netbeans IDE I am creating one project.That project(Web Application) needs properties file.Since my application is having several packages.And all packages need to read this properties file in their code.So where should I place this java properties file.If I place the file out side of the packages that is under sourcepackages seperately,I am getting FilenotFound Exception.So where should I place it.
And one more doubt is if I want to change any content in the file in future where should I change the contents since it is present in Projects folder and under Files->build->classes folder also.From where should I modify it.From where the changes will be effected.
Please help.
Thank you.
Put your file under /src/resources/, then use it like below:
ResourceBundle props = ResourceBundle.getBundle("resources.config");
You may put this in any package. The point ist to read with
MyClass.getResourceAsStream("my.properties");
Read further here.
You always change in the project src folder. The build folder is only for building your app.
If you want to change the properties file on a deployed system you may put the properties into the WEB-INF folder and then access with ServletContext#getRealPath().
I put the .properties file in the same folder as the src and it works :)
Alright, so I'm working on Windows and here's my solution...
It actually doesn't matter much where you put the .properties file--but assuming you created the file in NetBeans and let it save to its default location, you can simply call the data with the full directory attached.
Just for reference, here's what I did:
SimpleDataSource sds = new SimpleDataSource("src\\simpledatasource\\mystuff.properties");
Notice you'll need to escape the backslash, so use two of them.
How can we make a nested directory in resource folder to put the xmls with same name for different folders.And how we can read it using path in iphone app programatically?
Actually i want to make like resource>a>b>some.xml
again in resource like resource>f>g>some.xml
and so on...how ever both xml is containing different data in it.and also tell me the way how we can read it in iphone application.
You cannot use the same filename, even if they resides in different folders.
Instead, as a workaround, you can name the files like:
a_b_some.xml
f_g_some.xml
you can create a folder structure on your system and then directly add the folder to your XCode Project under resources by drag-drop.
this folder must display in BLUE color (physical grouping in folder on disk) rather than YELLOW (logical grouping in project only) just like native folders on mac. like this you can put same file in different folder hierarchy without any problems.
you need to create a absolute path to your file whenever you want its access your file [NSBundle pathForResource:] will not work in this case as it does not have access to your custom folder hierarchy.
best of luck.
i make a localized iphone application and in run time i want to modify the property list, so i at the first run of the application i copied the plist file but i don't sure if the copy operation also copied the localized version which the system store in a folder like: lp.fr
my quetion is: what i must do for the system to recognise the two files? should i make two directory in documents folder like lp.en and lp.fr and copy the two files?
also also xcode make the two plist with the same name, how i can determine every version and copy it?
i am waiting for some one to direct me to write way.
thanks
Take a look at NSBundle's pathForResource:ofType. It clearly states that it will return a non localized file if it exists or else pick a file in the order of user's language preferences. As you wan't to copy a localized resource, don't create a non localized copy and this will return the path for the most suitable resource. You can just copy that file and make changes to it.
If you are interested in getting the path to a resource of a specific language, take a look at pathForResource:ofType:inDirectory:forLocalization.
