A Maroto way to create PDFs. Maroto is inspired in Bootstrap and uses Gofpdf. Fast and simple.
Maroto definition: Brazilian expression, means an astute/clever/intelligent person.
You can write your PDFs like you are creating a site using Bootstrap. A Row may have many Cols, and a Col may have many components. Besides that, pages will be added when content may extrapolate the useful area. You can define a header which will be added always when a new page appear, in this case, a header may have many rows, lines or tablelist.

In the PDFs folder there are the PDFs generated using Maroto, and in the examples folder there are subfolders with the code to generate the PDFs. There are examples of: barcode, billing, certificate, custom pdf size, image inside grid, qrcode inside grid, sample with almost all features together, text inside grid, custom utf8 fonts (any language) and a label zpl.

We forked the repository from johnfercher/maroto with the tag v0.38.0.
We updated the maroto package with the following features/enhancements:
- Support auto line wrap with Chinese for the Text component.
- Add the
left,right, andbottommargins to the text properties of the Text component. - Add new helper function, CalcTextHeight, to estimate the height of multiple text lines of Text component.
- Support configable MaxGridSum, which default is
12, and add 2 helper functions, SetMaxGridSum and GetMaxGridSum. - Fix the issue of the floating position of page footer.
