NAME<\/a> display-file<\/b> : Render display into image file<\/p>\n display-file: [-flushcmd= Renders an image into a file. The file can be a framebuffer device (e.g. \/dev\/fb0<\/b>), in which case a reasonable representation of the image will be drawn on the console so long as<\/i> the program\u2019s mode matches the framebuffer\u2019s mode.<\/p>\n Note:<\/b> This target generates no input. The display-multi(7)<\/b> target can be used in order to see (and control) what the program does (using a normal target) and then generate a snapshot when the program exits.<\/p>\n filename<\/i> is the file to render the images to. If the filename is a PPM file (has the extension .ppm<\/b>), then the image will be generated at ggiClose(3)<\/b> time. Otherwise the file is a custom GGIFILE<\/i> format and is generated continuously.<\/p>\n The display-file<\/b> target can be used to generate movies from running LibGGI applications. To do this, set -flushcmd to a shell command to execute at the times given by one of the two other parameters. This looks typically like:<\/p>\n ppmtogif foo.ppm > foo.%04d.gif<\/p>\n The command is passed through a printf(3) which has the current count of saved frames as an argument (or rather as 10 arguments to allow a few more complex commands).<\/p>\n This shell command is either executed at every n<\/i>-th invocation of ggiFlush or every t<\/i> seconds, where t<\/i> can have fractional components (specified as decimal).<\/p>\n Note, that the invocation of the shell command will slow down the program, so make sure you use a reasonable value, if you use the -flushtime argument.<\/p>\n The primary file is updated before every invocation of the shell command.<\/p>\n \u2022<\/p>\n<\/td>\n DirectBuffer always available.<\/p>\n<\/td>\n \u2022<\/p>\n<\/td>\n Unaccelerated.<\/p>\n<\/td>\n display-file : Render display into image file <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[971],"tags":[973,1154,972],"class_list":["post-4074","post","type-post","status-publish","format-standard","hentry","category-7-miscelanea","tag-973","tag-display-file","tag-man7"],"gutentor_comment":0,"_links":{"self":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/4074","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/comments?post=4074"}],"version-history":[{"count":0,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/posts\/4074\/revisions"}],"wp:attachment":[{"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/media?parent=4074"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/categories?post=4074"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lode.uno\/linux-man\/wp-json\/wp\/v2\/tags?post=4074"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
