Thanks Uwe,
but do you know why the 575kb sized jpg becomes after
convertion to .png 2.8MB?
(i used convert)
Hi,
jpeg is more aggressive than png: It compresses more, but destroys the
image a little. png does not produce any artefact. You have no interest
to convert a jpg to a png, because the png image will have the jpeg
artefacts.
You could try to convert your eps to png.
- if your eps is a vectorial image, then it should not be so big and you
could use it directly or convert it to pdf.
- if your eps contains an photo, then use jpeg.
- if your eps contains an picture, but not a photo (i.e. a non-vectorial
drawing), you may prefer png to avoid jpeg artefacts.
Best regards,
Olivier
