• why need Middleware Engineering
• how to do it

Middleware Engineering 🔥, like multi-version Java full support(support low version Java and full functions of high version Java), is boring but essential for middleware! 🤣

Hi there,

This looks like a fantastic library. However I really need to support IE11 and I cannot find a browser support matrix in your docs... Am I missing it?

Thanks!
Kind regards,

This is not currently being tested, and as it is a template method, we don't even check it builds correctly.

Maybe something that searches for all *.jpeg in a directory, starts a thread pool, and in each thread, converts them to .png

This project does not have any transitive dependencies. However it sounds like we should still define a module name and specify the java classpath dependencies for this project, and other threadly projects.

Some relevant docs:

When num_tiles > range.size(), tile_evenly() should first clamp(num_tiles, range.size()).

Otherwise, we may end up with a tiling that isn't a tiling, or somehow doesn't make sense otherwise.

We have Bitmap image saving function void Save( const std::string & path, const penguinV::Image & image, uint32_t startX, uint32_t startY, uint32_t width, uint32_t height ) which locates in src/file/bmp_image.h and src/file/bmp_image.cpp files.

During file saving we purposely copy a line of image to temporary array and then write the array into file. The reason behind this is that
