most changes made for str width, height and xIncrement.... more to be done.
updates to padding and render logic changed more function calls!
reuse functions that take rounding into account
update file version and push error if its not a match
few missed usages commented out debug image output
cleanup some excess code change a few classes to use precise, mostly tooltips so the box fully encompasses the text
wasnt packing glyphs......
add sheet fixes, wasnt calculating and reseting values...... yeah.. reduced inner loops for the sdf function to speed up generation
fix missing characters in lucida, not converting to f32 was bad....
comment out debug output
change the sdf algo to calc the min middle distance as well increase the intensity to push closer to white apply a gaussian to the sdf after it is generated increase the padding to stop overlap issues.
the sdf method now tweaks the values based on inner or outer distance and sets the min and max accordingly, hopefully making sure 0.5 is the glyph edge.

I have a better method for doing this, the branch is out of date since the new changes and would make more sense to just use this branch as a reference. Will have a new PR up for doing this. |
