C++ (Cpp) flip_image_vertical Examples

Example #1

File: UI.cpp Project: RetroGamingArena/voxelengine

void UI::load_png_texture(const char *file_name)
{
    unsigned int error;
    unsigned char *data;
    unsigned int width, height;
    error = lodepng_decode32_file(&data, &width, &height, file_name);
    if (error) {
        fprintf(stderr, "error %u: %s\n", error, lodepng_error_text(error));
    }
    flip_image_vertical(data, width, height);
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, data);
    free(data);
}

Example #2

File: util.cpp Project: jlirochon/client

void load_png_texture_from_buffer(const char *in, int size) {
    unsigned int error;
    unsigned char *data;
    unsigned int width, height;
    error = lodepng_decode32(&data, &width, &height, (unsigned char *)in, size);
    if (error) {
        fprintf(stderr, "error %u: %s\n", error, lodepng_error_text(error));
    }
    flip_image_vertical(data, width, height);
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA,
                 GL_UNSIGNED_BYTE, data);
    free(data);
