## How to use
### Image watermarking
Command options are shown in both, shorthand and full name.
```bash
# watermark with all default options (on top left corner with 50% opacity)
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf"
# watermark at center
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" --center
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" -c
# watermark at right top with 20px offset from edge and full opaque
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" --offset-x=-20 --offset-y=20 --opacity=1.0
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" -x -20 -y 20 -o 1.0
# watermark at left bottom with 100px offset and 45 degree rotation
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" --offset-x=100 --offset-y=-100 --angle=45
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" -x 100 -y -100 -a 45
# stretch full with of page at page middle, with 30% opacity
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" --scale-width-center --opacity=0.3
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" -Wo 0.3
# Note the capital "W"
# stretch full with of page at page bottom
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" --scale-width --offset-y=-10
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" -wy -10
# Scale the image to desired percentage
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" --scale=30
# Add image as tiles all over the page
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" --tiles
# Add image as tiles with interleaved spacing
markpdf "path/to/source.pdf" "img/logo.png" "path/to/output.pdf" --tiles --spacing=20
```
### Text watermarking
```bash
# watermark text at right top with 20px offset from edge
markpdf "path/to/source.pdf" "The Company Name" "path/to/output.pdf" --offset-x=-20 --offset-y=20
markpdf "path/to/source.pdf" "The Company Name" "path/to/output.pdf" -x -20 -y 20
# Place text at center with bold-italic "Times Roman" font in blue color
markpdf "path/to/source.pdf" "The Company Name" "path/to/output.pdf" --center --font=times_bold_italic --color=0000FF
markpdf "path/to/source.pdf" "The Company Name" "path/to/output.pdf" -cf times_bold_italic -l 0000FF
# Place text at center with large bold-italic "Times Roman" font in blue color
markpdf "path/to/source.pdf" "The Company Name" "path/to/output.pdf" --center --font=times_bold_italic --font-size=24.0 --color=0000FF
markpdf "path/to/source.pdf" "The Company Name" "path/to/output.pdf" -cf times_bold_italic -s 24.0 -l 0000FF
```
#### Using placeholders with text watermark
The following placeholder can be used in text watermark:
- `{{.Page}}` prints the current page number
- `{{.Pages}}` prints the total page numbers
- `{{.Filename}}` prints name of the source file
```bash
# Using placeholders in text watermark
markpdf "path/to/083.pdf" "File: {{.Filename}} Page {{.Page}} of {{.Pages}}" "path/to/voucher_083.pdf" -x -20 -y 30
```
#### Allowed font identifiers
Currently the following font names are supported:
- **Courier**: `courier`, `courier_bold`, `courier_oblique`, `courier_bold_oblique`
- **Helvetica**: `helvetica`, `helvetica_bold`, `helvetica_oblique`, `helvetica_bold_oblique`
- **Times Roman**: `times`, `times_bold`, `times_italic`, `times_bold_italic`
### Additional notes
- **Specifying Colors**: write them as 6 or 3 digit hexadecilal as used in CSS, without the #
- `--color`, `--font` and `--font-size` flag has no impact for Image watermarking
- `--scale-*`, `--tiles` and `--opacity` flag has no impact for Text watermarking
- Negative offset will set content positioning from opposite side (right for offsetX and botom from offsetY)
- Text with opacity is not supported at this moment. Instead, you can [create a transperent background PNG image](http://www.picturetopeople.org/text_generator/others/transparent/transparent-text-generator.html) with your text and then use it for watermarking.
## Roadmap
✅ Draw image on every page of PDF
✅ Configure Opacity option
✅ Configure watermark position by X and Y offset
✅ Allow negative values to for offset to adjust from opposite direction
✅️ Easy option for positioning image at center
✅ Configure image rotation angle
✅ Options to Stretch watermark to page width or height, proportionately
✅ Options to Stretch watermark to page width or height at the middle of page
✅ Tile Image all over the page
✅ Render text on every page
✅ Configure text color, style and font
⏺ Configure text opacity
✅ Configure text rotation angle
✅ Text placement by offset
✅ Put text at page center
