If you see a white square make sure the height of your image is not greater than the y_position value you set.
To bypass this limitation you have to create an image with higher height.
Images must also not have Uppercase or Bad Characters (eg. *, à, ù, =, $, space etc.) in the filename or in the folders.
{% hint style="warning" %}
Keep in mind that the max size of a font image is 256x256.
This is a Minecraft limitation.
To bypass this (if you're creating a GUI or HUD) you can split your image in multiple font images and merge them shifting them.
{% endhint %}
Be sure to have each image size set to a multiple of 2.
Example:
- 2x2
- 4x4
- 6x6
- 52x52
- etc.
If you still have problems try to increase/decrease the size by 2 until the wrong shift disappears.
This is an approximation problem I cannot fix.
