Re: [Swftools-common] jpegdpi and ppmsubpixels obsolete in version 9

[Víctor Hugo]

Hi Ricardo thanks for your reply.

I use both parameters jpegquality to reduce the quality a bit and 
jpegdpi to reduce the pixels of pictures.

If I put 72 in jpegsubpixels don´t transform anything, I need set 
parameter to 1 or 0.5 to have changes in SWF.

I need know what is the transformation between 72 in jpegdpi and 1 or 
0,5 in jpegsubpixels.

Thanks and regards.
V.H.

jpegdpi and ppmsubpixels obsolete in version 9

Hi all.

I usually used jpegdpi and ppmsubpixels to set 72 pixels but in 9 version
this disappear, anyone know what parameter can I set to reduce my images to
72 pixels?

    

You can probably use subpixels parameter, like this:
pdf2swf -s subpixels=72 ....

This will set both jpeg and ppm in one "shot".

jpeg options in pdf2swf (0.9.0):

rica...@laptop:~$ pdf2swf -h | grep jpeg
-j , --jpegquality quality     Set quality of embedded jpeg pictures
to quality. 0 is worst (small), 100 is best (big). (default:85)

rica...@laptop:~$ pdf2swf -s help | grep jpeg
jpegsubpixels=<pixels>      resolution adjustment for jpeg images
(same as jpegdpi, but in pixels)
subpixels=<pixels>          shortcut for setting both jpegsubpixels
and ppmsubpixels
jpegquality=<quality>       set compression quality of jpeg images

Ricardo
