Thanks for suggesting to render an image from a font (I guess in some external image editor) and rotate the image. This will not work whenever the text is dynamically created (for example a hours and minutes clock.)
I wrote that I’m using LVGL on a monochrome OLED with LV_IMG_CF_INDEXED_1BIT. Or do you still think I can draw text in a canvas?
I thought the canvas draw methods were defective with 1-bit palettes?
Or can I draw to 1-bit canvases in version 8?
By the way, I added trying with styles to my howto request above. This method seems to be equally broken as with the canvas.
transform_angle only works on image-like objects as per its description in the style documentation, so unfortunately it won’t work on a label.
That is correct. The image will need to be true color, not indexed.
Sorry; I missed that. Drawing text on a canvas does not work if the canvas is indexed; the canvas needs to be true color. You should be able to use a true color canvas on a 1-bit display, but this only works if you have the RAM to spare.
