I had already searched for "SHGetFileInfo hidden" and found a useful post on a newsgroup mentioning LVIS_CUT. I took a dissassembler to comctl32.dll to find out what happens when LVIS_CUT is set and that led me to discovering the ImageList functions for the first time. Honestly, I couldn't get the colours right so to me it was a bad script.
. CreateIconIndirect creates a new icon, the old icon will be leaked if it's not destroyed manually.
I was attempting to work on a replacement post that hopefully did it properly. I still failed, but one of the things I did achieve was using the built-in IL functions for some things if it helps any:
Code: Select all
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
; Show a menu of the first n files matching a pattern, and their icons.
pattern = %A_ScriptDir%\*
n = 15

; Allocate memory for a SHFILEINFOW struct.
VarSetCapacity(fileinfo, fisize := A_PtrSize + 688)

I tried quite a few of them. Most are just synonyms for ILD_BLEND. ILD_TRANSPARENCY killed the transparency. ILD_BLEND25 makes things worse.
I tried RGB black and white, and CLR_NONE/CLR_DEFAULT to no avail. But I don't know what I'm doing here...
. As I don't know assembler, I rely on its decompiler a lot.
R.e. the brightness: I believe so.
