 Posted: Thu Jul 13, 2006 9:15 pm Post subject: Scrolling tray icon |
 |
|
This is a proof of concept, only. It works with 256 color 32x32 pixel bmp files, as tray icons, although it is easy to modify it for other sizes and bit-map formats, like .ico files.
The actual bitmap, one byte of color information for each pixel, is at the end of the file. We keep the beginning of the image file, read the first 31 rows of the image and the last row, and write into the same file swapped. Setting this as the new tray icon has the effect of the picture scrolled up cyclically by one pixel. Scrolling down is similar.
The hotkey Win-1 scrolls up, Win-2 scrolls down and Win-0 stops the icon. You can use your favorite one, or use the 3rd script to decode the Ascii85 encoded example. | Code: | file0= %A_ScriptDir%\l0.bmp ; <-- your bmp file
file = %A_ScriptDir%\l.bmp ; working copy

You can encode your favorite bmp file (for copying from the MsgBox to the script) with the following script: | Code: | nD := BinRead(file, D) ; include file and BinRead from above
Ascii85Encode(C, D, nD)
StringReplace C, C, ``, ````, All
StringReplace C, C, `%, ```%, All
StringReplace C, C, `), ```), All
Loop % (StrLen(C)+79)//80
{
StringMid x, C, A_Index*80-79, 80
B = %B%%x%`n
}
MsgBox %B%
Ascii85Encode(ByRef code, ByRef data, n=0) {
If n not between 1 and % VarSetCapacity(data)
n := StrLen(data) ; If no \0 in data, can omit n
x = 0
code = <~
Loop %n% {
x += *(&data+A_Index-1) << (24-8*((A_Index-1)&3))
If !(A_Index & 3) { ; Mod(i,4) = 0
IfEqual x,0, SetEnv code,%code%z
Else Loop 5
code := code Chr(33+Mod(x//85**(5-A_Index),85))
x = 0
}
}
If (n & 3) ; Mod(n,4) > 0
Loop % (n&3)+1
code := code Chr(33+Mod(x//85**(5-A_Index),85))
code = %code%~>
} |
Pressing Ctrl-C when the message box is active, copies the content to the clipboard, which you can paste to the script in an editor. This is how the encoded file is used (as Veovis suggested). | Code: | C =
