Introduction

Enables compressing PDF stored as attachments or in DB for any model by compressing its pictures content.

• Add pdf: Add some pdf attachments that contains images in the models.
  In the following example, we selected the sale model in my compression rule. So, we are adding 2 pdf files which contain images.
• Run the compression rule: Go to the corresponding compression rule and run it. The pdfs satisfying these rules should be compressed.
  The system will show a pop up with the details of the compression:
  compressed pdf and total size reduction
• Check results: Go back to the model where the pdf was uploaded and verify the results.
  Download the pdf and check the size reduction.
• File Store: Notice that upon running a compression rule or when the scheduled action runs them,
  the size of the filestore is reduced if Replace All was checked

• Setup a compression rule
  • Select the models where pdf attachments to be compressed.
  • Set the compression ratio
  • Set the optional minimum image width inside pdf attachment.
  • Set the optional minimum size of attachment.
  • Set the optional newer than/older than days to compress.
  • Set the quality of the compressed image (value between 0 and 100 where the larger the value, the higher the compression but the lower the quality)
  • In Odoo, storage is done by content. Thus, if the same pdf was uploaded twice, it will be saved on the disk once.
    Thus, there is an option to match all similar pdf, compress them and delete the uncompressed pdf.
    To activate this feature, check the "Replace All"
  • If you want the scheduled action to run this compression rule daily, keep it active.

• Scheduled Action
  Upon installing the module, a daily scheduled action "Run attachments compression rules" is added automatically
