Using script in Batch

[terrypin]

Anyone around with some scripting know-how please?

I recorded a simple script that operates on a PNG file using the PNG Optimizer to make the black background transparent and overwrites the original.

But how do I get this to work in Batch > Process so that I can convert the whole folder?

At present, with Batch > Process using the Obey Script option, it just repeatedly writes the same specific filename used for the recording.

There seems no way to invoke the Optimizer when just wanting to use plain Save. I can only access it if I first use File > Save As, or Copy As, or Export. And that codes the current name into the script.

If it's not possible to record it directly, then is there perhaps a term for 'current file' I can use in my text editor please?

You're still using PSP 8 correct?

Wish I knew more about that version. Upgrade man, it's easier for me to help that way. xD I'm sorry I'm just kidding...sort of.

Doesn't your version of PSP include a "Save as new type" option? Usually when you choose a type that includes options like PNG you can access the options that the batch processor uses. No need to use a script.

----------
If you want to use a script this is not hard but it's a bit annoying.

If all the files you currently have are already PNGs, then you just need to replace the FileName parameter with the variable App.TargetDocument.Name

Code: Select all

'FileName': App.TargetDocument.Name, 

If, however, you are using files of different types like BMPs, GIFs, or JPGs then you need to change the file extension of the image name before using it. The instructions for that are below.

I'm sure there's another way to do this using python basics but I'm going to have you use a library. So the first thing to do, if you haven't already, is to move your script into the scripts-trusted folder. I'm assuming you already did this because you're able to save. Or PSP8 works differently...I don't know.

At the top of the script add

Code: Select all

Import os

Then just before the "FileSaveAS" or "PNGOPtimizer" command (whichever one you used) add the following

Code: Select all

NewFilename = os.path.splitext(App.TargetDocument.Name)[0] + '.png'

Finally replace the Filename parameter with the variable NewFilename

Code: Select all

'FileName': NewFileName,

Many thanks. I'll get onto that in the morning.

They are all PNG files and, yes, I'm still using PSP8.

Yes, it does indeed, and that seems to be the obvious method. But it does not appear to let me access the PNG options!

So next I tried your 'generic filename' solution which looked very promising. But I'm afraid that failed too, giving me the 'Script could not be loaded' message when I tried it on a single file.

ORIGINAL RECORDED SCRIPT (Works OK)

from JascApp import *

def ScriptProperties():
return {
'Author': u'Terry Pinnell',
'Copyright': u'',
'Description': u'',
'Host': u'Paint Shop Pro',
'Host Version': u'8.10'
}

def Do(Environment):
# EnableOptimizedScriptUndo
App.Do( Environment, 'EnableOptimizedScriptUndo', {

})

# PNG Optimizer
App.Do( Environment, 'PNGOptimizer', {
'TypeOfTransparency': App.Constants.TransparencyType.SingleTransparency,
'Tolerance': 0,
'BoostAmount': 1,
'IncludeWindowsColors': App.Constants.Boolean.false,
'TypeOfImage': App.Constants.ImageType.TrueColor,
'NumberOfColors': 256,
'DitherPercent': 100,
'PaletteType': App.Constants.ColorSelection.StandardPalette,
'FileSubFormat': App.Constants.SubFormat.Interlaced,
'BoostSelectedColors': App.Constants.Boolean.false,
'TransparentArea': App.Constants.Transparency.OutsideSelection,
'TransparentColor': (0,0,0),
'FileName': u'C:\\Program Files\\MAGIX\\Movie Edit Pro 2014 Premium\\GeoModule\\Anima'\
u'tions\\Test conversion\\New Type Output\\Copy of Boots-DkBrownRight_99.png',
'Gamma': 45455,
'GeneralSettings': {
'ExecutionMode': App.Constants.ExecutionMode.Default,
'AutoActionMode': App.Constants.AutoActionMode.Match
}
})

REVISED BY EDITING only the Filename (FAIL with 'Script could not be loaded')
-----------------------------------------------------------------------------

from JascApp import *

def ScriptProperties():
return {
'Author': u'Terry Pinnell',
'Copyright': u'',
'Description': u'',
'Host': u'Paint Shop Pro',
'Host Version': u'8.10'
}

def Do(Environment):
# EnableOptimizedScriptUndo
App.Do( Environment, 'EnableOptimizedScriptUndo', {

})

# PNG Optimizer
App.Do( Environment, 'PNGOptimizer', {
'TypeOfTransparency': App.Constants.TransparencyType.SingleTransparency,
'Tolerance': 0,
'BoostAmount': 1,
'IncludeWindowsColors': App.Constants.Boolean.false,
'TypeOfImage': App.Constants.ImageType.TrueColor,
'NumberOfColors': 256,
'DitherPercent': 100,
'PaletteType': App.Constants.ColorSelection.StandardPalette,
'FileSubFormat': App.Constants.SubFormat.Interlaced,
'BoostSelectedColors': App.Constants.Boolean.false,
'TransparentArea': App.Constants.Transparency.OutsideSelection,
'TransparentColor': (0,0,0),
'FileName': App.TargetDocument.Name,
'Gamma': 45455,
'GeneralSettings': {
'ExecutionMode': App.Constants.ExecutionMode.Default,
'AutoActionMode': App.Constants.AutoActionMode.Match
}
})

P.S: What are all those 'u's which appear in all my scripts?

The "u" prefix is used in python to define a unicode string object.

If you run the script on a regular image, not a batch image, it should give a more specific error in the Script Output palette. Can you tell us what that is?

Thanks, understood. (I'll ignore it!)

Running my recorded script
Executing RunScript
Executing EnableOptimizedScriptUndo
Executing PNG Optimizer

Running the edited script
Executing RunScript
File "<string>", line 1
from JascApp import *
^
SyntaxError: invalid syntax

That makes no sense to me, as most of the scripts I use contain that first line, but hopefully it will mean something to you!

Any thoughts on why your first (script-free) idea didn't cut the mustard please?

Script failure solved!

Turned out to down to an obscure problem with my text editor, the 'Write Unicode...' setting in my text editor. I vaguely recalled some problem with this years ago, when editing an INI file mysteriously hadn't worked. So I tried pasting the recorded script into Notepad instead and it worked. Back in TextPad I removed the checkmark from the Unicode thing - and that then also worked!



And the original problem has also now been identified, as in latest posts here:

Thanks again for your help.
