JPEG support with ijg - getting access violation

Question

I was recently trying to update my game to store graphics in compressed formats (JPEG and PNG).

Whilst I ended up settling on a different library, my initial attempt

Answer 1

To work with images in multiple formats, let me recommend you DevIL as a library http://openil.sourceforge.net/. It's an excellent choice, as I've used it many times with excellent results. Beware that it's syntax is OpenGL-like.

The list of features:

Supports loading of:

• .bmp
• .cut
• .dcx
• .dds
• .exr
• .ico
• .icns
• .gif
• .jpg
• .jp2
• .lbm
• .lif
• .mdl
• .pcd
• .pcx
• .pic
• .png
• .pnm
• .psd
• .psp
• .raw
• .sgi
• .tga
• .tif
• .wal
• .act
• .pal
• .hdr
• Doom graphics

Supports saving of:

• .bmp
• .dds
• .jpg
• .pcx
• .png
• .pnm
• .raw
• .sgi
• .tga
• .tif
• .pal
