This commit is causing following errors:

I was following instructions here:

https://heaps.io/documentation/hello-hashlink.html

My set up:

$ hl
HL/JIT 1.14.0 (c)2015-2023 Haxe Foundation
  Usage : hl [--debug <port>] [--debug-wait] <file>

$ haxe --version
4.3.6

I undid the commit to previous code in BitmapData.hx and the error went away. I am not very well versed with Haxe to debug this.

CC: @yuxiaomao Thanks.

Thank you for reporting this. Indeed, you'll need to add -lib format now (install with haxelib git format https://github.com/HaxeFoundation/format before new release), because some functions API are moved from haxe std (for haxe 5.0) to lib format (image conversions are not really meaningful for std).
I just updated the doc, should be sync to wiki / heaps.io soon!
