Mirage Source

I split this from the other topic because my additions were getting pretty off topic..

PNG = Lossless
Gif = Lossy
Jpg = Lossy

My question is this: If you zlib compress a bitmap, is it smaller than a jpg or png? If not, how much difference in size (average) is there?

[edit]
Found my answer... PNG is smaller than zlib compressed bitmaps.

[edit again]
I can be an idiot some times.. (No comments necessary..)

I ran the test with zlib compression (using my bitmap utils..) and the image was compressed smaller than a PNG... Then, I did a bunch of images, and forgot to select zlib, so I thought the files were much larger than the pngs... I wondered what I was seeing before.

I also added in the max compression routine for the bitmaputils.. (Considering releasing a new version...) and the 'normal' compression is smaller than png.. The 'max' compression is yet even smaller.. So.. I have changed my mind about adding png support to my bitmaputils.. I'll just leave it as is, but maybe release a new version with compression level support.

[Last Edit]
Here is a comparison of BMP files vs PNG files vs ZLIB Normal Compression vs ZLIB Max Compression

where do you zlib compresser, and could you use it to replace all the bmp files to save space? and run smoother?

Thanks Verrigan. I'll be sure to use your encryption software in the future.

do we need a DLL files to make it work?

You mean you don't need Zlib.dll?
