fast picture format conversion

8 posts in this topic

hello,

in my program i have to convert several .pngs into .jpgs because autoit doesn't support .png.

searching the forum i found two command line tools, "topng.exe" and "pvw32con.exe" but neither of them is clearly explained. at least, pvw32con supplies a good documentation, so i got it running like that:

Run(@ComSpec&" /c "&"pvw32con.exe *.png -j",$pluPath,@SW_HIDE)

this line converts all pngs in the specified folder to jpgs.

nevertheless i am not satisfied because the line needs about three seconds to convert 12 images and this seems to me way too slow.

so does anyone give me an idea for a faster way? maybe my line can be "straighter up" (do i have to use the dos command line?) or i could use a dllcall function, but please, give me a working example line and not just a general comment because i am quite a newbie.

thanx

j.

try Irfanview. You can download a standalone DLL from their website that will do exactly what you want

please guys,

this sort of answer i have read about a thousand times here in this forum. this does not help.

what is the name of the dll ? how is it used? please an example line or two !

i cannot find a single standalone dll on the website. and the iv help doesn't help either. i don't want to use this entire program by command line.

so, anyone ?

j.

It's not a stand alone "DLL".

I really hope you weren't talking to me. My "one" sentence was so that you'd stop waisting your time looking for the "stand alone" dll.
