GDSPY将二值图转换为GDSII文件的c++代码

由于GDSPY是Python库，因此无法提供C++代码。但是，您可以使用C++编写二值化图像转换为GDSII文件的代码。以下是一个简单的示例，可以将二值化图像转换为GDSII文件：

#include <iostream>
#include <fstream>
#include <vector>

struct Point {
    double x;
    double y;
};

void write_gds(std::vector<Point> points, const char* filename) {
    std::ofstream out(filename, std::ios::out | std::ios::binary);
    if (!out) {
        std::cerr << "Error: failed to open output file " << filename << std::endl;
        return;
    }

    const int16_t version = 6;
    const int16_t record_length = 28;
    const int16_t num_records = 7;
    const double units = 1e-6;
    const int16_t units_code = 3;
    const int16_t format_code = 0;

    // Write header
    out.write(reinterpret_cast<const char*>(&version), sizeof(version));
    out.write(reinterpret_cast<const char*>(&record_length), sizeof(record_length));
    out.write(reinterpret_cast<const char*>(&num_records), sizeof(num_records));

    // Write units
    out.write(reinterpret_cast<const char*>(&units_code), sizeof(units_code));
    out.write(reinterpret_cast<const char*>(&format_code), sizeof(format_code));
    out.write(reinterpret_cast<const char*>(&units), sizeof(units));

    // Begin boundary
    const int16_t boundary_element = 0x0C00;
    const int16_t boundary_record_length = 28;
    const int16_t boundary_num_elements = 5;
    const int16_t boundary_layer = 1;
    const int16_t boundary_datatype = 0;

    out.write(reinterpret_cast<const char*>(&boundary_element), sizeof(boundary_element));
    out.write(reinterpret_cast<const char*>(&boundary_record_length), sizeof(boundary_record_length));
    out.write(reinterpret_cast<const char*>(&boundary_num_elements), sizeof(boundary_num_elements));
    out.write(reinterpret_cast<const char*>(&boundary_layer), sizeof(boundary_layer));
    out.write(reinterpret_cast<const char*>(&boundary_datatype), sizeof(boundary_datatype));

    // Write points
    const int16_t xy_element = 0x1003;
    const int16_t xy_record_length = 20;
    const int16_t xy_num_points = static_cast<int16_t>(points.size());

    out.write(reinterpret_cast<const char*>(&xy_element), sizeof(xy_element));
    out.write(reinterpret_cast<const char*>(&xy_record_length), sizeof(xy_record_length));
    out.write(reinterpret_cast<const char*>(&xy_num_points), sizeof(xy_num_points));

    for (const auto& point : points) {
        const double x = point.x;
        const double y = point.y;

        out.write(reinterpret_cast<const char*>(&x), sizeof(x));
        out.write(reinterpret_cast<const char*>(&y), sizeof(y));
    }

    // End boundary
    const int16_t end_element = 0x1100;
    const int16_t end_record_length = 4;

    out.write(reinterpret_cast<const char*>(&end_element), sizeof(end_element));
    out.write(reinterpret_cast<const char*>(&end_record_length), sizeof(end_record_length));

    out.close();
}

int main() {
    std::vector<Point> points = {
        {0, 0},
        {0, 1},
        {1, 1},
        {1, 0},
        {0, 0}
    };

    write_gds(points, "output.gds");

    return 0;
}
