Microsoft Word -> PDF image quality -

-

our line of business application uses word document template, fills in pertinent information , converts pdf, returns user.

that works fine except 1 thing. use image of our company's logo on lead page , in footer. in 1 resolution (e.g. 100%), looks fine. @ higher resolutions (e.g. 250%), has several noticeable jaggies; diagonals have noticeable ragged edges. tweaking image, we're able make @ higher zoom value, looks terrible @ lower zoom values.

currently, we're using png, we've tried jpg , doesn't improve jaggy problem. in fact, looks worse @ higher resolution because of jpg compression. think vector image solve problem (and have logo in vector format), haven't found vector formats word supports.

i don't have code show, since don't image in code: take document , plug in our values, none of touch logo (the template contains image).

we using word 2013 (32-bit) on windows 8.1 (though of our developers use windows 7). use .net pdfdocument class generate pdf.

any ideas on how word better @ retaining image quality? or pdf issue?

the suggestion david van driessche might still work, provided right emf used. emf files can contain both raster , vector data. raster emf file, same problem present did png or jpeg. vector emf embedded in word files can scale nicely, @ least when zoomed in display, work printing or converting pdf.
word supports both raster , vector objects within emfs, secret use emfs contain scalable objects lines, curves , text when quality & scaling both concerns.

i have posted sample files here illustrate wishing see difference.
