 Posted: Thu Apr 27, 2006 1:25 am Post subject: File size changes when edited |
 |
|
I appears that my GIF files sizes are changing when I edit a photo, i.e. do a red eye fix. For instance I had a file for from 1035KB down to 775KB. How do I prevent this from happening?
thanks,
Markus |

Out of curiosity, why do you have megabyte sized GIFs of people (presumed content given red-eye fix)? Unless you're intentionally down-sampling the color depth, the GIF format is pretty poorly suited to capturing 'real life' images. Even though JPEG is lossy, it's almost always more faithful to the original scene than GIF, with much smaller file sizes.
For any compressed file format, if you alter the image composition the file size would likely change, due to greater or lesser efficiency in compression. Some programs will do lossless optimization of formats with a specific color table (like GIF and PNG) - though I can't say if PJ does that. |

I wished to duplicate my private answer here but I see that Charles already responsed to you  Thanks Charles.
Of course the files were in JPEG format and after each editing and saving JPEG format recompressed and depending from the JPEG quality size might be differ than original. By default PicaJet uses 90% quality value for saving jpeg files. It's optimal combination of JPEG quality and JPEG file size. |
