text2png : OLED 64x32

[yboujraf]

Dear @tkrkt , @adityapatadia , @bashaus , @greyvugrin , @philipeachille

I 'd like to use your library to generate 1 or 2 or 3 or 4 lines in a 64x32 pixels picture. Each line could have different fonts and sizes depending of the number of lines.

• Is it possible to extend the library to define the high and width of the png ?
• There is a way to calculate the font size to be sure the text will fit in the line ?
• There is a way to dis/enable wrapping the text to the next line if text is bigger than the width.

the ouput file could be an array or buffer.

This a layout I am looking to do by using javascript or typescript to generate on the fly the png to display to a oled display

Hi @yboujraf ! I have only contributed a few lines of code to "text2png", I used it in another project's context, where it was helpful.

What you are looking to do is quite simple with the Jimp library, eventually in combination with text2png (for my purposes last time, Jimp's text processing was inferior to text2png).

Thanks for your quick reply.

Here I have 51 OLED BUTTONS on a remote panel and all are subscribing to a parameter. This parameter has properties (name, description, value, format, ....) Then each time the value change, I need to update the oled.

I am looking for performance converter text to png or bitmap buffer. If you know any other library you are welcome.

Best Regards, Youssef

I am afraid, I can't recommend any other libs
