I'm trying to script an ellipse drawing algorithm in AutoIT for learning purposes.
I use an edit control to "draw" the ellipse with characters.
The code i have works kinda good but i would like to see if others around here know a better algorithm to do it..
I would like to be able to give the x, y and width, height arguments to the function and not have to start at the middle point and draw the ellipse around it.
side note, the ellipse glitches when it has to be 2 pixels high too..
func ellipsePlotPoints ($xc,$yc, $x,$y) pixel ($xc + $x, $yc + $y) pixel ($xc - $x, $yc + $y) pixel ($xc + $x, $yc - $y) pixel ($xc - $x, $yc - $y) endfunc func ellipse($xc,$yc, $a,$b) local $a2 = $a * $a local $b2 = $b * $b local $twoa2 = 2 * $a2 local $twob2 = 2 * $b2 local $p local $x = 0 local $y = $b local $px = 0 local $py = $twoa2 * $y ; Plot the initial point in each quadrant. ellipsePlotPoints ($xc,$yc, $x,$y) ; Region 1 $p = int($b2 - ($a2 * $b) + (0.25 * $a2)) while ($px < $py) $x+=1 $px += $twob2 if ($p < 0) then $p += $b2 + $px else $y-=1 $py -= $twoa2 $p += $b2 + $px - $py endif ellipsePlotPoints ($xc,$yc, $x,$y) wend ; Region 2 $p = int ($b2 * ($x+0.5) * ($x+0.5) + $a2 * ($y-1) * ($y-1) - $a2 * $b2) while ($y > 0) $y-=1 $py -= $twoa2 if ($p > 0) then $p += $a2 - $py else $x+=1 $px += $twob2 $p += $a2 - $py + $px endif ellipsePlotPoints ($xc,$yc, $x,$y) wend endfunc
WinSetState ("[CLASS:OpusApp]", "", @SW_SHOWMAXIMIZED) and WinSetState ("[CLASS:OpusApp]", "", @SW_MAXIMIZE) don't maximize the window. Using WinSetState("[CLASS:OpusApp]","",@SW_RESTORE) allows me to maximize it about 15% of the time. I've tried using WinMove("[active]",0,0,@Desktopwidth,@Desktopheight), but that only makes it worse. I've also tried putting in a sleep and maximizing it again. Does anyone have a solution?
Here's my code:
The startup script is intentionally commented, because I'm not testing it right now. The other comment is just for debugging when I need it.
UPDATE: When I run two instances of the program, it works almost all the time, but if I copy the code inside the else statement twice it doesn't work at all (despite the fact that it's running the same code just in one program vs two). I also noticed that when I run two instances of it, about 50% of the time when it opens both the windows, it also hits the windows button and types the letter d into the search box. Neither of these actions are in my code. I'm not really sure what's going on.
I know many newbies search for this feature.
I decided to share this piece of code with everyone.
Basically its a "splash screen" that has a transparent image.
In a nutshell - Gui with a transparent gif.
Splash Screen GUI.zip
_ArrayDisplay($aArray, "Window Title", "1:", 0, Default, "Column") ; Expected results are rows 1 to the end of the array, all columns. The result is rows 0-1, all columns. The API reference is here:
Am I doing something wrong?
So I thought it would be cool to use my Gravatar account to display my gravatar in a local GUI.
I use this code:
#cs ---------------------------------------------------------------------------- AutoIt Version: 18.104.22.168 Author: Skysnake Script Function: Example to download avatar from Gravatar and display locally #ce ---------------------------------------------------------------------------- ; Script Start ; includes #include <Crypt.au3> #include <InetConstants.au3> #include <MsgBoxConstants.au3> #include <WinAPIFiles.au3> #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <WinAPI.au3> ; declare Global vars Global $md5GraMail = '' ; will store email for Grvatar request request GravatarLogin() GetAvatar() Func GravatarLogin() ; get the email required for downloading the Gravatar Local $sGraMail = InputBox("Get Gravatar", "What is your email registered with Gravatar?", "firstname.lastname@example.org", "", -1, -1, 0, 0) ; from http://en.gravatar.com/site/implement/hash/ ; make the hash ; Local $dHash = _Crypt_HashData(GUICtrlRead($g_idInputEdit), $g_iAlgorithm) ; Create a hash of the text entered $md5GraMail = _Crypt_HashData(StringLower(StringStripWS($sGraMail, 8)), $CALG_MD5) ; lose the left two '0x' chars and convert to lower case $md5GraMail = StringLower(StringTrimLeft($md5GraMail, 2)) ; Display the result.

While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd ;FileDelete($MyGravatar) ; Delete the file. FileDelete($sFilePath) EndFunc ;==>GetAvatar Now, here is the issue.
If I use the example from the Gravatar site, located here:
Then this code 205e460b479e2e5b48aec07710c08d50 downloads this pic (not me)
AND it displays correctly.
However, If I download my own Gravatar, I see the image in the @Script folder, BUT IT DOES NOT DISPLAY. The same with the retro image. To be clear, this image downloads, but is not displayed.
I guess it has something to do with the format of my gravatar. Or that the display funtion GUICtrlCreatePic() does not like my gravatar.
I would be grateful if someone would be willing to test this and may offer a suggestion or two...
