for example i have FlxText object
var t:FlxText=new FlxText();
I can show on my app the unicode symbol for example "1" , use
t.text="1";
t.text="\n0031";//work too
but i can't show the unicode symbols(from same font), like
t.text="🗻";
t.text="\u1F5FB";// mount fuji
then i compile my project to cpp debug and can't see mount_fuji symbols. Only square frame.
What wrong with me? :)
Code tested on win7 64.
Codes was taken use FontForge programm. Any help will be good

After building bootstrap, it generated b2 but it did not generate bjam(I guess that should be fine because b2 is the new name and bjam is the new one). All the libraries are generated fine in Stage/lib. But I get this error now LNK1181. looks like that stage.obj file is not generated, not sure why.
Is there any way I can Ignore this error? This code was written in 1997 maybe in VS2013, we don't even use boost anymore. But there are so many dependencies, I have to use it. FYI same code works fine in VS2003.
Any help would be appreciated, I am a newbee to visual studio(Hope this question is not silly).

I am trying to customize the color of the LaTeX inline formula when using Sphinx documentation package, and html output.
The details:
I have a file called func.rst, which includes the following line:
Let :math:`x_{1}` be a binary variable.
which is rendered successfully into LaTeX in the documentation I created with Sphinx.
(I have 'sphinx.ext.imgmath' listed in extensions in conf.py)
My goal is to have x_{1} colored in red.
Things I tried:
Adding the color inside the formula:
Let :math:`\color{red}x_{1}` be a binary variable.
while also defining
latex_elements['preamble'] = '\usepackage{xcolor}'
in the conf.py file.
Trying to define all math output globally with:
latex_elements['preamble'] = r'''
\usepackage{xcolor}
\everymath{\color{red}}
\everydisplay{\color{red}}
'''
Needless to say, both (and many more less promising ideas) failed.
Copying over my answer on cross-posted question at tex.sx:
As you seem to be targeting html with math rendered as PNGs images (or SVGs), the current config value to configure isn't latex_elements, but imgmath_latex_preamble.
I tested since and it works.
For completeness sake, I am adding here the full solution. (THANKS jfbu!)
In conf.py I defined extensions = ['sphinx.ext.imgmath', <some_more_unrelated_stuff>]
Also in conf.py I defined
imgmath_latex_preamble=r'\usepackage{xcolor}'
(EDIT: in ooposed to what I previously wrote,there is no need to define in addition imgmath_latex="/usr/local/texlive/2017/bin/x86_64-darwin/latex" thanks jfbu again)
In the .rst file where I have the latex expression, I have
Let :math:`\color{red}x_{1}` be a binary variable.
In the terminal I run
make clean html
("make clean" is the sphinx's best friend)
And its working! wohoo!
Sorry about the short title, but I honestly can't get a better description of what is happening because I don't know enough...
Some background first, I am "converting" a multi-byte application to support unicode and I've made the standard char/string wchar_t/wstring changes and the my code is building without problems.
What happens is that when the application is being initialized it hits an assert when it registers the applications's document templates. The code is the standard
CMultiDocTemplate* pRepDocTemplate = NULL;
pRepDocTemplate = new CMultiDocTemplate(IDR_DIAGNOSTIC_REPORT_TYPE,
RUNTIME_CLASS(CDiagnosticReportDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(CDiagnosticReportView));
and CDiagnosticsReportView has the standard DECLARE_DYNCREATE and IMPLEMENT_DYNCREATE in the header and source.
The assert is at doctmpl.cpp line 29 (mfc120ud.dll - at least is using the correct dll), but I can't find the source code anywhere to actually know what is happening.
The inheritance tree is pretty straightforward:
CDiagnosticReportView
\->CReportViewBase
\->CXTPReportView
\->CView
CXTPReportView is part of a framework that we are using which is provided by Codejock (Codejock extreme toolkitPro). From the build pane I know that it's linking against it's unicode debug dll (ToolkitPro1631vc120UD.dll)
Suffice to say that in the multibyte configuration this problem doesn't occur.
The project is configured to use the UNICODE character set (Project properties->Configuration Properties->General->Character Set).
Any help would be appreciated!
Thanks in advance!
It all had to do with the fact that I was linking against the non UNICODE build of Codejock. Even though I saw a reference to the UNICODE dll, the lib wasn't the correct one!
Problem was solved when I opened my eyes ;)
I'm porting an OpenCV 2.2 app from Unix (that works) onto Windows 7 64-bit and I receive the following exception when cv::imwrite is called
"OpenCV Error: Unspecified error (could not find a writer for the specified extension) in unknown function, file highgui\src\loadsave.cpp"
The original unix app works fine on my Mac and Linux boxes.
Does anyone know what library or compiler config I could be missing that makes this work on Windows?
UPDATE:
I did the following things to get OpenCV running:
Downloaded the binaries for v2.2 from the OpenCV site for windows. I'm using 2.2 because the original app uses it and I don't want to complicate my build at this stage.
I am trying to imwrite to a .png file. I looked at the OpenCV code and noticed the necessity for external libs for Encoders such as Pngs or jpegs, so I tried writing to .ppm, .bmp which seems not to require deps, but I get the identical error.
An example of my usage is cv::imwrite("out.png", cv_scaled); where cv_scaled is of type cv::Mat with format CV_32FC1
Please remember the identical code works fine in unix
The fact .bmp or .ppm doesn't work this raises more questions:
Why don't these very simple formats work?
Is there a way to see a list of installed Encoders programmatically?
Thanks again for your kind assistance in helping me debug this problem.
Your current installation of OpenCV doesn't support the file format you are trying to create on disk.
Check if the extension of the file is right. If it is, you'll have to recompile OpenCV and add support to this format and possibly install the libraries you are missing.
That's all that can be said without more information.
EDIT:
As I have also failed building an application that uses the C++ interface of OpenCV (v2.3 on VS2005) I ended up using the following workaround: convert the C++ types to the C types when necessary.
To convert from IplImage* to cv::Mat is pretty straight forward:
IplImage* ipl_img = cvLoadImage("test.jpg", CV_LOAD_IMAGE_UNCHANGED);
Mat mat_img(ipl_img);
imshow("window", mat_img);
The conversion cv::Mat to IplImage* is not so obvious, but it's also simple, and the trick is to use a IplImage instead of a IplImage*:
IplImage ipl_from_mat((IplImage)mat_img);
cvNamedWindow("window", CV_WINDOW_AUTOSIZE);
// and then pass the memory address of the variable when you need it as IplImage*
cvShowImage("window", &ipl_from_mat);
Try
cvSaveImage("test.jpg", &(IplImage(image)));
instead of
imwrite("test.jpg", image);
This is a known bug in the version you are using.
From the OpenCV 2.2 API:
The function imwrite saves the image to the specified file. The image format is chosen based on the filename extension, see imread for the list of extensions. Only 8-bit (or 16-bit in the case of PNG, JPEG 2000 and TIFF) single-channel or 3-channel (with ‘BGR’ channel order) images can be saved using this function. If the format, depth or channel order is different, use Mat::convertTo , and cvtColor to convert it before saving, or use the universal XML I/O functions to save the image to XML or YAML format.
You might have more luck converting your file to 8 or 16 bits before saving.
However, even with single channel 8 bit files I have had unknown extension errors trying to save jpg or png files but found that bmp works.
I'm trying to use the new OpenCV 2.0 API in MS Visual C++ 2008 and wrote this simple program:
cv::Mat img1 = cv::imread("image.jpg",1);
cv::namedWindow("My Window", CV_WINDOW_AUTOSIZE);
cv::imshow("My Window", img1);
Visual Studio returnes an unhandled exception and the Console returns:
OpenCV Error: bad flag (parameter or structure field)
(Unrecognized or unsupported array type) in unknown function,
file ..\..\..\..\ocv\opencv\src\cxcore\cxarray.cpp, line 2376
The image is not displayed. Furthermore the window "My Window" has a strange caption: "ÌÌÌÌMy Window", which is not dependent on the name.
The "old" C API using commands like cvLoadImage, cvNamedWindow or cvShowImage works without any problem for the same image file. I tried a lot of different stuff without success.
I appreciate any help here.

As I just commented, imread isn't working for me either. A little googling shows other people having the same problem; I guess it's a bug in the library code. For now, here's a hacky workaround:
IplImage* img = cvLoadImage("lena.jpg");
cv::Mat lena(img);
cvReleaseImage(&img);
This way, you can at least use the C++ API for the rest of your stuff.
There's help for this issue.
The solution is, that the usual proposed opencv library files in the linker are not working properly. Instead try to use the debug library files by this:
In Visual C++:
go to Project->Properties (or Alt-F7)
Configuration Properties->Linker->Input->Additional Dependencies
replace the usual
" cv210.lib cxcore210.lib highgui210.lib" by
" cv210d.lib cxcore210d.lib highgui210d.lib" - which are the debugging libraries.
The OpenCv 2.0 API commands should work now.
I had the same problem described above which turns out to be caused by the settings of the linker.
I found the answer in another thread,
OpenCV 2.3 and Visual Studio 2010.
To repeat it here:
Properties of your project (right click on it)
C/C++
General
include directory add the < your directory >\OpenCV2.3\include\opencv2, < your directory >\OpenCV2.3\include\opencv and < your directory >\OpenCV2.3\include
Linker
General
List item
Input
Add all the libs like opencv_core230d.lib opencv_highgui230d.lib and so on...
Once I've done the above, I can run imshow and imread + all other cpp functions seamlessly! OP's problem has probably already been resolved, but hopefully this will be useful to other people who are led here looking for the same solution.
Are you sure you added the whole path starting from /home/.... I had the same problem as you but when I added the whole path, things work out pretty well. The whole path had to be added despite the fact the path exists in the include files.
imread in openCV unlike Matlab does not return an error when file/folder is not found - instead it returns a null matrix, which in turn is reflected as an error during imshow.
Also, imread does not look for image files in the included folders or the workspace. So, specify the entire path whenever possible.
Please take a note of this for future references.
Firstly, you'd better compile your own version OpenCV.
I had the same error with the build (I got from Sourceforge), and solved by compiling my own version in debug and release versions.
And make sure you change the original system env variable PATH to the new build folder build/bin, then you could build and run the imshow() in Debug mode.
I believe this might be related to unicode.
Try the macro _TEXT()
For example:
cv::Mat img1 = cv::imread(_TEXT("image.jpg"),1);
