When I use the code
canvas1.createRender(100);
canvas1.setTextSize(100);
uur=random(23);
minuut=random(59);
seconde=random(59);
sprintf(charBuffer,"%02d:%02d:%02d",uur,minuut,seconde);
int nWidth = canvas1.textWidth(charBuffer);
nWidth is zero. How can I get the width of a string?
When I test is wihth :
nWidth = canvas1.textWidth("test");
the answer is sill zero.
Any sugestion?

Thanks Lukas, The problem was loading the font from the internal file system.
After delete all these, and place Serial.begin in the right orde loading of the fonts was no problem. Even my DSEG7Classic-Regular.ttf was loaded correct, and display correct. Converted it with the python file ttf2bin.py was also a succes in use.
One question remains. The command "createRender(168, 256)" is used for drawing bigger text, but are there limitations?
In my case when I put a larger value as 168 the screen still blanks, notting happens, but no error message shows up. The documentation is a bit fuzzy. Please can you explane this command.
@flypeek When I Run the example file, the load of the font file gives the message
FT_Stream_Open: opened `/GenSenRounded-R.ttf' but zero-sized. But the file is'nt empty.
Any idee?
When I load the font from the example M5EPD_TTF get the message
"FT_Stream_Open: opened `/GenSenRounded-R.ttf' but zero-sized"
What is the meaning of this message?
Hello,
Thanks again. Have a very simple question. Is running the example "M5EPD_TTF" on your M5Paper? I have stored the font on my sd card as in the example above but and get strange things on the window when running this example.
Second thing what is the benefit using the fontedit program? I have used the tool ttf2bin.py and convert a a standard ttf font, put it un the sd card and tried it to use. No result.
As the example shows, the M5Paper could use standard ttf files as on my computer. Is that right.
For me the M5Paper is not usable at the moment. Too bad about all that money.
I have a number of M5Stack items and I am very satisfied with them, but not bad about this one.
When I load the font file with canvas1.loadFont("/GenSenRounded-R.ttf", SD);
the result is "zero". Is this meaning there is an error?
File can be found in M5EPD_TTF example (arduino ide)
When I load the font with "canvas.loadFont("/GenSenRounded-R.ttf", SD);"
the result is zero. Is this meaning there is an error?
The file GenSenRounded-R.ttf is in the example file M5EPD_TTF.
Thanks for the response.
do you have experience with the tool ttf2bin.py?
It is in lib M5EPD/tools.
How can I convert a standard font to a file I can use with thw M5Paper.
I need the 7 segment led font in my program
@powersoft
Found the solution. After setting into the preference the right url and loading the m5stack I was able to choose the M5Paper. Examples are running now👍
@zontex
Have running all demo programs
Here the results:
Button: failed
DISPLAY_URL_JPG: failed
HELLOWORLD: pass
M5EPD_TTF: failed
RTC_BM8563: pass
SHT30: pass
TOUCH: failed
This is very strange!
@zontex
That's working fine! Tried this several times with succes!
When compiling the examples I use the board "M5Stack-Fire".
When I try to run the example "M5EPD_TTF" then it is not workin, blank screen. Have you tried this example found in the example directory?
The SHT30 example is working fine.
All thing related to the canvas like fonts, drawing etc gives the problem.
Do you have could run all example files?
@zontex yes,the upload is okee. I found also when I chanhe the font the output is not working. By the way all examples in the ide ore not working wich are manipulating the canvas.
@zamzam
Do you have tried to slow down the upload speed. Had the same with other brands, after reducing the upload speed it works.
Succes,
Jan
Hello,
When I load an example from the Arduino IDE "HelloWorld" the screen is staying blank. Some other also.
Is there a solution of this problem?
Thanks for any help.
