[Inkscape-user] Vectorize png

hello,

i have one question about vectorize png images: The default png image has a size of 130 KB, after vectorize with 64 scannings with 64 colors (stapel) and save it as .svg i have a file of 2.6 MB!! when i open the file with kwrite it is a simple xml document with maybe two dinA4 pages, what is on it 2,6MB?? what can i do to make my svg files smaller, and save the same quality? I thought svg is a way, to comrimize images, instead of png. are there datas from inkscape (0.41) whitch are saved with the image? regards:

PS: have you got a mandrake or ubuntu package of 0.42 or later?
