FAQs
- Question: What are all these PNGOUT options?
- Answer: Check out this PNGOUT tutorial
on Ken Silverman's (the creator of PNGOUT, which PNGGauntlet uses for compression) site. In general, the default
options will get you the smallest file.
- Question: Why does it take so long to compress a file?
- Answer: PNGOUT works really hard to compress your images to the smallest possible size.
That just takes some time.
- Question: Why do the progress bars jump back and forth?
- Answer: The progress bars take progress information from PNGOUT. PNGOUT makes several passes
over the image trying different techniques to compress the files. What you're seeing is the progress of each of
these passes.
- Question: Why does PNGGauntlet need the .NET Framework?
- Answer: PNGGauntlet is developed in C#, using the .NET Framework. This means you need to have the
framework installed for it to run.
- Question: I compressed an image with alpha, and now the alpha doesn't show up in my editor. Why?
- Answer: To minimize file size, PNGOUT will compress 32-bit (RGB+Alpha) images down to 8-bit with
palletted alpha if it can. While 8-bit paletted alpha images work fine in many editors and in all web browsers that
support transparent PNGs, it does not work in Photoshop, Gimp, or Paint Shop Pro. If you want to edit the
compressed images in any of those programs, you should choose the "RGB+Alpha" color depth in the Advanced
Options panel when compressing files that have an alpha component.
- Question: Hey, can you make PNGGauntlet use multiple processor cores to compress images?
- Answer: While it would be pretty easy to add multicore support for PNGGauntlet, I will not be doing it.
If you want to take advantage of multiple processor cores, go buy PNGOUTWin from
the original creator of PNGOUT. PNGGauntlet would be nothing without Ken Silverman's PNGOUT, so I'd rather you support his product
than make PNGGauntlet do everything.
- Question: PNGGauntlet said that the new size of my file was larger than the original
size! How can I keep it from doing that?
- Answer: Sometimes PNGOUT just can't make a file smaller, and sometimes it actually comes up with a larger
file than what went in! PNGGauntlet will tell you what happened by displaying the new file size and percentage increase in
file size, and will color the file red. However, it'll just copy the original file to the output instead of the larger one, so
you don't have to worry about files ever getting larger.
