有没有办法让xcb把一个文件加载到一个像素图中？

#include <xcb/xcb.h>

xcb_connection_t *connection;
xcb_screen_t *screen;

// 打开与X服务器的连接
connection = xcb_connect(NULL, NULL);

// 获取默认屏幕
screen = xcb_setup_roots_iterator(xcb_get_setup(connection)).data;

xcb_window_t window;
xcb_gcontext_t gc;

// 创建窗口
window = xcb_generate_id(connection);
xcb_create_window(connection, XCB_COPY_FROM_PARENT, window, screen->root, 0, 0, 800, 600, 0, XCB_WINDOW_CLASS_INPUT_OUTPUT, screen->root_visual, 0, NULL);

// 创建绘图上下文
gc = xcb_generate_id(connection);
xcb_create_gc(connection, gc, window, 0, NULL);

xcb_image_t *image;
xcb_pixmap_t pixmap;

// 加载文件到像素图
image = xcb_image_create_native(connection, width, height, XCB_IMAGE_FORMAT_Z_PIXMAP, depth, NULL, size, data);
pixmap = xcb_generate_id(connection);
xcb_create_pixmap_from_bitmap_data(connection, pixmap, window, image->data, image->width, image->height, image->stride, image->depth, image->bpp, XCB_IMAGE_FORMAT_Z_PIXMAP, 0, NULL);

// 绘制像素图
xcb_copy_area(connection, pixmap, window, gc, 0, 0, 0, 0, image->width, image->height);

// 刷新窗口
xcb_flush(connection);
