finite_draw_reset_offset

The finite_draw_reset_offset function attempts to undo a previously applied Cairo translation on the active drawing context.

void finite_draw_reset_offset(FiniteShell *shell, double x, double y);

Parameters

Type	Description
`FiniteShell *shell`	The active `FiniteShell` containing the window.
`double x`	The horizontal offset to reverse.
`double y`	The vertical offset to reverse.

Code Example

#include <finite/draw.h>

// Apply a translation
cairo_translate(shell->cr, 64.0, 32.0);

// Undo the translation
finite_draw_reset_offset(shell, 64.0, 32.0);

Notes

This function applies a cairo_translate(cr, -x, -y) to the active Cairo context.

This function does not reset the Cairo transformation matrix and only reverses a translation operation.

Standard Usage

This function must be provided a valid FiniteShell.

This function requires a valid Cairo context in FiniteShell.cr.

This function should only be used to reverse a translation when the original offset values are known.
