File Sequence UDF

FileSequence UDF

My job requires me everyday to work with a LOT of file sequences, mostly image file sequences. So I created this UDF. I use it to batch convert image sequences to quicktimes, resize, rename, move, backup, count total frames ...etc... I use it for image scanning, but you can use it for any files numbered. Just type in the extention you need.

In this UDF, I consider a file sequence to be of more than 3 consecutive files. Example:

C:FolderImageSequence_001.tga
C:FolderImageSequence_002.tga
C:FolderImageSequence_003.tga
....
--> C:FolderImageSequence_###.tga

Example: If you scan this folder : "C:Folder", looking for extentions like "jpg tga mov", then the function may return an array like this:

$array[0] = 3
$array[1] = C:FolderImageSequence_#####.tga
$array[2] = C:FolderImageSequence_Converted_####.jpg
$array[3] = C:FolderSubFolderquicktime movies ###.mov")

You can convert the returned file sequence to format %0id or wildcard with the provided functions:

C:FolderImageSequence_###.tga
--> C:FolderImageSequence_%03d.tga
--> C:FolderImageSequence_***.tga

C:FolderImageSequence_######.tga
--> C:FolderImageSequence_%06d.tga
--> C:FolderImageSequence_******.tga

This UDF is a relatively fast folder scanning UDF, scanning ~40 GB with about 100 file sequences (~5000 images) and gathering all the informations (Sequence length, Sequence Range, Dimensions, FileSize ...) takes about 6-7 seconds on my computer.

Remark: parts of this UDF require IrfanView, which you can download for free on their website (www.irfanview.com). I am currently converting this part of the UDF to use the FreeImage UDF instead. The UDF also uses "Array.au3" and "GDIPlus.au3".

Functions:

_FileSequence_Convert (uses IrfanView)
_FileSequence_Copy
_FileSequence_Delete
_FileSequence_Exists
_FileSequence_Find (Main function)
_FileSequence_FSToRegExp
_FileSequence_FSToWildcard
_FileSequence_GetFileName
_FileSequence_GetImageDimensions
_FileSequence_GetParentFolder
_FileSequence_GetRange
_FileSequence_GetSize
_FileSequence_Move
_FileSequence_Rename
_FileSequence_Resize (uses IrfanView)

If you see anything that could be improved, please tell me, I'd be happy to make it even faster! Comments and critics welcome! Tell me what you use it for, I am curious!

Wow ! that's exactly what I was searching for !! Also works in vfx industry and work with a lot of file sequences, and I'm writing concept of a new custom software that will require heavy sequences work.

Will try your UDF, many thanks for sharing.

It's very useful with programs like Nuke and PDplayer, because they both require file numbering in format #### or regexp %0xd. In PDPlayer you can use the filesequence UDF to auto convert your sequences in Quicktime for example.

I also use it to backup 3dsmax files, which I usually save incrementally. So you can create a small program that scans for 3dsmax files sequences, and then backup them to a zip file. I think this UDF can be used for so many purposes. I use it everyday. :)

Ahah seems we use exact same tools ! Happy to see AutoIt used in this industry, a real winner. Could be better in some aeras and faster, but so easy to develop and deploy lot of little tools here and there in our workflow.

Cheers :bye:

      Hey everyone,
      I thought I might share my little Language UDF plus the more powerful SciTE Tool to ship Strings from SciTE into the xml file. While I haven't had the time to fully adapt the small UDF to one of the big XML-UDFs the so called "Language Transmitter" that basically writes the XML file for you runs mostly on "XML DOM wrapper (COM)" by eltorro. The Transmitter should work with other XML-Language-UDFs depending on their encoding.
       
      First let's start with the UDF, there are two functions of interest: _LangInit($sFilePath) and s($sString) As you will have guessed, _LangInit($sFilePath) is called once to initialize the UDF and s($sString) is used to receive the string to your key. Plain and simple.
      Now to the actual "new" part, the Language Transmitter. It basically allows you to transfer a selected String from SciTE into a xml file. While doing so it will scan for AutoIt variables, macros etc. and parse the string to fit StringFormat(). It then saves the formatted string in the xml file and returns the formatted call into SciTE. If the selected string is already defined it will directly parse the key into SciTE. To change the default output file, you can either edit the ini-file in the @ScriptDir of the LanguageTransmitter.exe or press Alt+A on empty space again and keep clicking cancel/no until the Transmitter let's you select the current output file. Standard output is strings.xml in the current opened AutoIt Script.
      Example:
      ; given the line: MsgBox(16, 'Error', 'Error message') ; select 'Error' run the Transmitter follow the instructions, repeat with 'Error message'. Outcome (e.g.): MsgBox(16, s('Error'), s('Error_msg')) ; Variables and Macro example: $sString = "Value: " & $iValue & @CRLF & 'Another value: '& $iValue2 ; Select the full string including all AutoIt variables and macros etc. in SciTE and press Alt+A (default) to run the LanguageTransmitter ; follow the instructions and it will then paste a formatted string like that into SciTE: $sVar = StringFormat(s('Key'), $iValue, $iValue2) ; the correlating xml entry should look like that: ; <string name="Key">Value: %s\r\nAnother value: %s</string> ; as you can see @CRLF has been replaced with \r\n as well. If you are working on a project and want to directly add a string to the xml file just start the Language Transmitter without selecting any text, enter your string and a key.
      SetUp/Installation
      Examples
      Since xml files are required all examples can be found in the zip file. There are two examples, one includes a language selection interface.
      Language File Checker
      I added a script to check whether the xml file contains all required strings or even unnecessary strings.
       
      Hope you like my little helper!

      Dear AutoIT Community.
      I am currently working on a program that will display lots of images in a scroll down GUI.
      I create the GUI based on the number of images, which works fine.
      But all images I place using GuiCtrlCreatePic above a threshold of around 32000 pixels (cant say exactly) are placed at negative locations and finally will reach 0 again
      and will then populate on top of the images placed there before.
      For $i = 1 To $Images[0] ; Get picture dimensions $hImage = _GDIPlus_ImageLoadFromFile($ImgRep & $Images[$i]) $iX = _GDIPlus_ImageGetWidth($hImage) $iY = _GDIPlus_ImageGetHeight($hImage) _GDIPlus_ImageDispose($hImage) ; Resize & place images in GUI $Pic[$i] = GUICtrlCreatePic($ImgRep & $Images[$i], $Spacer, Round($yPos, 0), $MaxImgWidth, $MaxImgWidth * ($iY / $iX)) $yPos = $yPos + $MaxImgWidth * ($iY / $iX) + $Spacer $log = $log & "|" & $yPos $currentlut = $Images[1] Next I have found a limit at 32767 pixels for some GUI elements when googling around.
      Can someone tell me how to circumvent that?
      thanks!
      cheers

      Hello all!
      I use Autoit for a while, already made some automation for a TV station's master control room with it. I made a UDF to easily work with PAL timecode and time with milliseconds, convert, add or subtract them. Feel free to use it if you want something like this
