FreeType Cache just keeps growing

[GlovePuppet]

I have an application with a lot of strings at different font sizes. All the text is rendered using the same font.

As I walk through my menu system I see memory being allocated as more glyphs are cached by FreeType's cache manager. Eventually all the available heap is allocated and the device resets.

I can work around this by unloading/loading the font every time I update text on the screen but it's not a great solution. Rendering speed is not noticeably worse which makes me wonder if the cache is required at all?

Is there a better way to flush free type's caches or reduce/control its memory usage??

Hi @GlovePuppet
Thank you for using this library 😊

This issue has been reported as #17.

Currently there is no limit on the cache size, but it will be set to a minimum in the next update.
The develop branch already has this fix in place.
Please wait a little longer for the master branch to be updated.

You can also use the following API to change the cache size.

void setCacheSize(unsigned int max_faces, unsigned int max_sizes, unsigned long max_bytes);

Be careful, this API must be called before the loadFont method.

Thank you.

Thank you, this has solved my problem.

Also, thank you creating this project, it really improves the "look" of my text display

The master branch has been updated to v1.1.
The default cache size has been set to the minimum.

I am really sorry for the late update🙇‍♂️🙇‍♂️🙇‍♂️
