Save Print Screen screen shots

22 posts in this topic

#1 ·  Posted (edited)

Here something I have been wanting for a while now. The basic functionality is there.

The script sends a printscreen and then saves the bmp on the clipboard to a file.

; AutoIt Version: 3.1.1 (beta)
; Language:       English
; Author(s):      Steve Podhajecki [eltorro] gehossafats@netmdc.com
; Description:    Save PrtScr from clipboard as bmp file using AutoIt3 and API
;                  No extra dll's required.
;                  Works on XP  should work on OS >= Win2k
; Thanks to Valik for finding buffer error

Woops, the pasted code is correct, the attached file was incorrect .

I have uploaded the correct file now. All the extra functions are included in the script.

Here something I have been wanting for a while now. The basic functionality is there.

The script sends a printscreen and then saves the bmp on the clipboard to a file.

eltorro- This is a wonderful tour-de-force of AutoIT programming that I have learned a lot from. That being said, I find that using Irfanview in command line mode gives me enormous power to do the same thing, but with the additional options of scaling, renaming, jpeg, gif, etc., as well as the ability to print, clip, and change color depth all at the same time. I use it daily to capture screen shots of remote computers on our network...

...by the way, it's pronounced: "JIF"... Bob Berry --- inventor of the GIF format

Irfanview is a awsome program (It's on my flash drive, and BartPe disks). I have used it for a number of years. I find the Gimp to be very useful too. There are other means $$$. That said, the overhead for saving a screen shot from the example I posted is quite a bit smaller than either of those as all the dll's used in the script are part of the os.

I have plans to add this to some other scripts.

Using the Clipboard udf I posted. It is possible to make a script that "watches" the clipboard and if a bitmap is placed on it, it will automagically save the shot. I'm sure game enthusiast would like something like that. There are other pratical uses beyond that though.

I am exploring using GDI+ to convert the image from bmp to jpeg. GDI+ comes standard on WinXP but is a SDK item prior to that.

Can you pm me the screen shot? Also what program are you using to view the image?

Edit: I have checked my saved shots with Irfanview, MSpaint, and TheGimp.

Are there any errors in SciTe's Console window?

eltorro,

I wish I could say that I love your scripts, but I can't get either one to run without throwing an error:

AutoIt3.exe has encountered a problem and needs to close. We are sorry for the inconvenience.

AppVer: 3.1.1.132 ModName: ntdll.dll

And it asks if your want to send an error report to Microsoft. (I don't think so.)

I have tried the pasted version and the downloaded version with the same results.

I am running WinXP Pro with SP2. What's going on?

I had some fatal errors that I never had when I used .132 this morning with EnCodeIt. It bottomed out in a For/Next loop that I tracked down, but that had never happened before... ran it with .131. It was almost like it didn't like how fast the loop was going, because when I put a Sleep(10) in it just for giggles, wouldn't you know it worked :whistle:

SmOke_N,

Thanks for the tip on the difference between betas.

I went back to .131 and now SavePrtScBMP.au3 (downloaded version) runs fine.

@eltorro - The pasted version in the first post is different from the downloaded version. It does not produce a .bmp file when it's run.

I fixed that earlier, see the first post.

I had some trouble with the script too. For some reason if I put the file write funcs in a seperate udf, the troubles disappear. I made a post in support to that effect.

Good work! Nice that it done without external references.

Bitmap is saving, but it skewed by 7 pixel:

I hadn't notice till I read your post this morning.

I have been trying to resolve the issue of the 7 pixels.

Change the code to read:

ElseIf ($biCompression) Then
                If ($biCompression = 3) Then
                    $NumCols = 11

and it seems to be fine.

Probably need to see if it works with 16bits bmps too.

eltorro,

Just so you know. The pasted script in your first post does not work.

I just thought you should know, because I would want someone to tell me if my script didn't work, instead of just passing it by.

This is a greet little screen capture program.

I was wondering if it is possible if someone could help me as i was wondering if it is possible instead of saving the file as the name clipboard it would change it would be possible to save it as the username,pcname,date and time. I have tried this but it didn't like it.

I can get the File save as box to appear but it then stops.

I am a newbie so please help as i have looked in the help file and i have managed to create the following line as the save as string (which i think is correct).

$filename = @UserName & " on " & @ComputerName & " at " & @HOUR & "." & @MIN & "." & @SEC & " on " & @MON & "-" & @MDAY & "-" & @YEAR & ".jpg"

I have posted the same question here

http://www.autoitscript.com/forum/index.ph...f=2&t=31180

so if an administrator would like to either merge or link the topics that would be helpful
