ghostscript - How to convert PDF to Image without generating a file -

-

based on code how-to-convert-pdf-to-image-using-ghostscript-api

i trying figure out how image foreach page without creating files

to image foreach page setted outputtomultiplefile = true.

then went step step through code wasn't able find part files created.


want know need change in code?
or else helps achieve this

edit

here current parameters:

args[0] = args[1] =-dnopause  args[2] =-dbatch  args[3] =-dsafer  args[4] =-sdevice=pnggray  args[5] =-r130  args[6] =-soutputfile="c:\scannen1.pdf%d.png"  args[7] ="c:\scannen1.pdf"

you need use device doesn't write file, all image format devices write output file. use display device return bitmap in memory template , write own device, or can modify 1 of existing devices.

modifying existing device task developer , while not excessively difficult not trivial either.

in event, aren't going want fiddling command line switches. sinatr i'm puzzled can usefully ghostscript doesn't involve writing file.

oh, 1 other possibility load nulldevice, done in postscript , bit bucket.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
