Saving image as JPG -library?
I'd like to find a JPEG-writing library that can be statically linked (so there are no DLL dependencies). No JPEG-reading ability is required.
Edit: I got LibGD working, but it had开发者_如何学运维 one problem described here:
LibGD library is not working: crash when saving image
libjpeg is the most popular library for saving jpegs, but it can be a bit of a pain to use.
Edit, here is a simple example of how to use it. Look for the function juce_writeJPEGImageToStream.
Have you looked at LibGD? I can't seem to find the license, but neither did you specify a requirement.
If you're running your application on Windows then you should use the standard, built-in "GDI+" library that Microsoft provides. Every computer running XP or later has this library.
GDI+ is intended to supersede GDI, which is what you're probably already using whether you know it or not, but it can co-exist with GDI calls provided you flush the buffers when switching between the two. See:
