Image Sequence Padding

[FredP]

I am having to find the "padding" of an image sequence.

 

Padding is the number of digits used in the sequential filename.

 

Filename_00001.tga

Filename_00002.tga

 

Has a padding of 5 digits.

 

In other scripting languages I have used, that is represented by %d5.

 

What I need to do is Identify the padding, and then use that number to call a specific frame number up.

 

"%d"&Length ( filename::firstframe )

 

the field firstframe based on the above example would have 00001 in it.

 

So to call up frame 25 in other scripting languages, I would use "25 %d5" which would become 00025 with the correct padding.

 

I am sure there is a way to do this in filemaker, but I dont know which function to use. Any help would be appreciated.

Wouldn't your example be either a padding to 5 digits or a padding of 4 digits? 00005.tga?

 

"FileName_" & Right ("000000000000000000000"& $Currentdigit), $PaddingToUse & ".tga"

 

would output FileName_00003.tga if you feed it 3 for $Currentdigit and 5 for $PaddingToUse.

 

 

Or did you mean going the other way, feeding it a string like "FileName_00003.tga" and having it output how many padding zeros got used?

 

Let (rightofdash = Middle (fullstring, position (fullstring, "_", 1, 1)+1, length (fullstring) ); PatternCount (rightofdash, "0") )

 

ought to output 4 if you feed it "FileName_00003.tga" in a field/variable 'fullstring'

00001 I consider padding 5 digit padding.

 

00023 I also consider 5 digit padding.

 

Is that what you are asking? I consider the total digits the amount of padding.

 

I am having to generate a frame 0 for an image sequence via a script. In order to write out frame 0, I need to know the padding involved.

 

So

 

Filename_001.jpg

 

would get a file written out which is

 

Filename_000.jpg

 

But

 

Filename_000001.tga

 

would get a file written out

 

Filename_000000.tga

 

In order for the frame filemaker creates to be considered part of the sequential sequence, the filename as well as the padding needs to be the same.

 

So essentially, i think your first example is what I need.
