Make text BOLD and ITALIC or BOTH when creating PDF

My finds on it:
1- Font file is used to make text bold, italic or both.
2- We can add 2 or 3 layers of same text with small offset to the Point location and it will look like a bold
3- To user insert_html

For me I have fixed repository of font files. I can keep multiple version of a Base Font. Like one for Calibri regular, then italic, bold, semi bold and so on
I also tried getting bold using offset but that looks odd.

I cant get to find anything that I can use with insert_text.

I am still searching more on insert_html, but looking for something straight forward

To start with insert_htmlbox:

• There is no parameter in the method directly to use a certain font of desired characteristics. You must use HTML / CSS syntax to select a font of your liking. As for the standard variations, you can simply specify the HTML construct <b>bold text</b>. The MuPDF Story behind the method will locate a suitable / available font. Same is true for semi-bold etc.: use CSS syntax to define a @font-face.
• As is true for all text insertions, outputting exactly the same text and a rectangle with exactly the same width and height, plus a small (!) shift will simulate bold or even character shading.

In addition to the previous, Page.insert_text()/Page.insert_textbox() also support the border_width and the render_mode parameters which generates the PDF command Tr (text rendering). The default value 0 Tr writes the character interiors (only, i.e. "fill"), 1 Tr writes character borders (i.e. "stroke"), and 2 Tr writes both.
Combining both parameters, achieves a number of effects like documented here.

Finally, you can use the morph=(point, matrix) parameter to simulate more effects like italics and shrinking / stretching by using point to be the insertion point in insert_text(point, ...) and a suitable matrix.

Here is an example script for some of these things.

Thanks. It helped
I talked to few people regarding font families. I was unawared that for Bold italic and other styles, different font files are used of same family. I mean using Calibri-Regular, we cant get Bold or Italic text. Then I wanted to explore if there is any way that a single file can contain mapping against all styles.
Couldn't find anything

I have concluded that, font styles and weights are properties of Font and not Text.

Correct findings! The usual variants (regular, bold, italic, bold-italic) require 4 different font files. Inevitably.
With an appropriate CSS definition of the font family, the selection of the right variant is automatic whenever you use the respective HTML constructs <b>, <i> etc.
