|
|
1) Uncompress the PDF file
|
||
|
|
|
||
|
|
```shell
|
||
|
|
nix-shell -p qpdf
|
||
|
|
qpdf --qdf --object-streams=disable input.pdf uncompressed.pdf
|
||
|
|
```
|
||
|
|
|
||
|
|
or
|
||
|
|
|
||
|
|
```shell
|
||
|
|
nix-shell -p pdftk
|
||
|
|
pdftk input.pdf output uncompressed.pdf uncompress
|
||
|
|
```
|
||
|
|
|
||
|
|
2) Edit the PDF as "plain text" file
|
||
|
|
|
||
|
|
Works:
|
||
|
|
|
||
|
|
- With `LC_ALL=C sed`
|
||
|
|
- `LC_ALL=C sed -e 's|some text||g' uncompressed.pdf > uncompressed-output.pdf`
|
||
|
|
|
||
|
|
Does **not** work:
|
||
|
|
|
||
|
|
- With `nano` by pressing `ALT` + `r` (search and replace). The resulting PDF is distorted - some text is missing or misaligned.
|
||
|
|
|
||
|
|
Untested:
|
||
|
|
|
||
|
|
- With a text editor using "search and replace". Warning, on large files this might be laggy.
|
||
|
|
|
||
|
|
3) Compress the PDF
|
||
|
|
|
||
|
|
```shell
|
||
|
|
qpdf uncompressed-output.pdf output.pdf
|
||
|
|
```
|
||
|
|
|
||
|
|
or
|
||
|
|
|
||
|
|
```shell
|
||
|
|
pdftk uncompressed-output.pdf output output.pdf compress
|
||
|
|
```
