hm


I think the dpi and ppi issue should be cleary discussed here ^_^

when we say Dots per Inch, we are meaning the size of each dot is to be 
printed. The resolution  of the output Device. Pixels per Inch means the 
same, but to related to  the size of the image in the monitor.
An image can have as many dpi as you want... the same 300x300px image 
prints 1x1in in a 300DPI printer. When we set the print for 600DPI it 
prints at 0.5x0.5in... 150DPI prints at 2x2in and so...
Thats the reason Gimp can play with de ppi of the image, withou 
re-scaling. It is only a reference. In fact, pixels are all that matters 
inside the computer.
If you have an 1024x768 image (common screen res) divide it by 300dpi 
(the printed output, in the case), a 3.41x2.56in image and your have top 
quality graphs.... but, you do not need to have 300dpi if you think your 
image is going to appear too small. Do not Interpolate, transfroming the 
image to 2048x1576px to achieve 6.82x5.12in (got it? pixels are the only 
real value you must care), you must, in the case, use a 200dpi or 150dpi 
output, it should not be that bad, cause you are dealing with 
screenshots, not art pictures ^_^

6.82x5.12in is 17.32x13mm ... it is more than A5 width, for a book, you 
could use 10x7,5mm ... 1024 / 10mm = 260Dpi output! O_O it is quite 
good, dont you think ? .. I do ^_^

   Thanks a lot for this useful info.

   

   "...you must, in the case, use a 200 dpi or 150dpi

   Great, I noticed that even in top quality books, sometimes the screenshot illustrations less sharp than the other artworks. 

This is probably because of the difficulty of producing real high quality screenshots we are discussing here.
