Hello,

Thank for your answers. Since I use this image with a background, I need the transparency. So as tylerdurden suggested, I will use svg for my edits then save as a pdf.

Hello, Strange things happen when I try to save a png within a pdf. Here is my example : I first import the falcon.png image in inkscape then I save it as a pdf (dessin-1.pdf). Everything seems ok then I reopen it and save it a second time as a pdf (dessin-2.pdf). Now the image appears to be darker ...

Thank you for the answer. Googling a little bit from your answer helped me to understand this (not so) strange behavior.

Hello everyone,

I use to produce pdf graphs with R then I like to modify them using inkscape. Yet when I increases font using text tool , letter size increases but letter spacing doesn't as you can see in example.
Does any one else have this problem ? Thank for your help.
