PNG vs GIF

Brian,

Any thought of supporting PNG’s? I played around with a converter today and the screenshot went from a 42K gif to a 25K png with no apparent loss of quality.

Depends what the image is - if it’s a vector format then png can be extremely efficient, but for a full colour image the file size can be very high.

I was referring to the screenshot generated by WD, which seemed to me to be the most complex gif that it produces.

WD Linux uses only png. Screenshot here created a 41K image

my graph images appear to be about 1/3 smaller than yours (12K vs 18K)

i have found a png component I can use
but i have stuffed up the library search paths in the compiler when i went to install it
and now i can do anything

I guess there are PNG’s and PNG’s. The online converter I tried earlier today reduced the gif file sizes, but a batch converter I just downloaded from tucows made most of them bigger :? Guess it wasn’t such a good idea after all…

i got the compiler sorted out…
and have created a png image OK
of the screen shot
png: 36.8k
gif:42.4k

not a big difference
and a fair bit of work in wd to add option to use it…

Not worth the effort in that case.

well when making a png you can change compression, among other things. That could be why the batch converter made them bigger.

No compression, all the extras: screen shot 418K 8O
Full compression, nothing extra: screen shot 17K

i will check on the compression capability and test that

and this is 9 compression level


setting 8bit format, i can get the screen shot down to 20k
with png

but the icon does not look so good
but for other images where there is not much colour then its a good size saving
i cant see where to set the compression level yet…

i have not got the time to work on this at the moment at this time of year
too many angry customers as it is

Brin,

a lot of PDAs are not able to read PNG-files!

So if someone uses his PDA-browser, he cant see anything that is a PNG!

it would only be an option to use png, if i were to add it
png means portable network graphics, and yet a portable notepad PC cant use it…go figure
