Completeness / clipping

[newinnovations]

This is just to check if my observations are correct and I don't start implementing stuff in a fork that is already there.

Basically I have the need for a variant of Page::to_pixmap that allows for a clipping rectangle for zooming into an area. There doesn't seem to be a utility function in mupdf-c that implements that. In py-mupdf it was added in 2016 (pymupdf/PyMuPDF#54).

I set out to implement the functionality in Rust, but could not find references to functions like fz_transform_rect and fz_round_rect.

My question boils down to:

• is there a variant of to_pixmap available that allows for a clipping rectangle
• if not, are the basic mupdf functions required to implement it available through mupdf-rs

this?

mupdf-rs/src/rect.rs

Lines 188 to 190 in 168fcb6

	pub fn transform(self, matrix: &Matrix) -> Self {
	unsafe { fz_transform_rect(self.into(), matrix.into()) }.into()
	}

and https://docs.rs/mupdf-sys/latest/mupdf_sys/fn.fz_round_rect.html

[newinnovations]

Great. Exactly what I was looking for!

But why do I get

no method named `transform` found for struct `mupdf::Rect` in the current scope
method not found in `Rect`

is it not part of 0.5.0?

yes, it was added recently, if you want to contribute you should work with the current main branch.
