finite_draw_set_offset

The finite_draw_set_offset function attempts to set an offset for future drawing.

void finite_draw_set_offset(FiniteShell *shell, double x, double y)

Parameters

Type	Description
`FiniteShell *shell`	The FiniteShell where the window is.
`double x`	The X offset.
`double y`	The Y offset.

Code Example

#include <finite/draw.h>

// create a color for later
FiniteColorGroup grayGlass = {
    .r = 0.152,
    .g = 0.152,
    .b = 0.152,
    .a = 1
};

double miniWindow[4] = {
    ((shell->details->width  * 40) / 100), // x
    ((shell->details->height * 20) / 100), // y
    ((shell->details->width  * 55) / 100), // width
    ((shell->details->height * 60) / 100)  // hieght
};

finite_draw_set_offset(shell, miniWindow[0], miniWindow[1]);

finite_draw_rounded_rect(shell, miniWindow[0], miniWindow[1], miniWindow[2], miniWindow[3], 35, &grayGlass, NULL, true);
FiniteColorGroup outline = {
    .r = 0.788,
    .g = 0.788,
    .b = 0.788,
    .a = 0.4
};

finite_draw_stroke(shell, &outline, NULL, 6);

Notes

This function is used to offset the drawing position of all draw functions. Even though some functions may manually take in x and y positions, they are universally affected by this function.

If shell.cr is undefined, this function will create a new Cairo draw tool and set it to shell.cr

Standard Usage

Offsets apply to everything drawn after it’s been set as long as it’s using the same shell.cr.

You should at some point call the inverse of this function (finite_draw_set_offset(-x, -y)) to reset the offset back to 0,0.

This function must have a valid FiniteShell

This function uses Cairo which requires a valid cairo_surface_t in FiniteShell.cairo_surface beforehand.
