Import and Update PDF Export Preset

Question

Hey there again!
I'm now trying to define a preset for the PDF Export process... it's based on the "High Quality Print" (from the Adobe PDF Preset list), and then I want to change "one or two" parameters.
Changing one or two parameters is easy, I've been doing that already, but since most of them are already defined by the "High Quality Print" Preset, my idea was:
Load the "High Quality Preset"
And after that change the required parameters
And then export to PDF of course!
How can this be done?
Many thanks!!
Best regards.

@m8r-vrpa5v – I think, it is not best practice to change a default PDF Export Preset. Instead I would add a new preset based on the default one.
When looking at your code you have to use the right syntax.
Every time you assign a value to a property you have to use the right object that property belongs to.
Some values are only functional, if some other property is set (this goes especially for the bleed settings).
Do not write:
bleedTop='0mm'; 
ExtendScript cannot know by itself where this property and its value should be assigned to what object.
Right syntax would be:
myPDFExportPreset.bleedTop='0mm'; 
Or (I used no meassurement units, the value 0 does not require this):
myPDFExportPreset.properties = { 
useDocumentBleedWithPDF : true, 
bleedTop : 0 , 
bleedBottom : 0 , 
bleedInside : 0 , 
bleedOutside : 0 
Hi Uwe,
Thanks for your remark... that was my mistake when using copy paste.
I was reusing code from another script where I used the WITH function, in here I was using a different structure and I didn't correct this.
But thanks again for the remark!
