arcan(1) User manual arcan(1) NAME aloadimage - Trivial image viewer for Arcan servers SYNOPSIS aloadimage [global_options] file1 file2 ... DESCRIPTION aloadimage displays images over an arcan connection point. Each image is parsed in a separate and sandboxed process. If multiple images are pro- vided, a certain number of items will be processed in advance. OPTIONS -a, --aspect image into output window, maintain source image aspect radio and pad with a background color. -S, --server-size Scale source images to fit server- suggested content size. This changes the primary type from MEDIA (server side scaling) to APPLI- CATION (client defined scaling). -l, --loop When the playlist reaches the end, it will loop back from the begin- ning rather than shutting down. -t, --step-time Set the playlist automatic stepping time (default: 0, manual con- trol). The time unit is in ticks on a 25Hz clock. -b, --block-input Ignore all keyboard and mouse input. -d, --display connpath By default, the ARCAN_CONNPATH environment is used in order to find an arcan instance to connect to. This argument ignores that in favor for the connpath argument. -p, --padcol ,g,b,a When running in a scalemode where source size != destination size and output window cannot be resized, the default behavior is to cen- ter image and pad the sides. This argument can override the default colors with the restriction that all four channels should be pro- vided and only decimal encoding in the range 0-255 is accepted. -m, --limit-mem limit(mb) Limit the maximum decoded memory sized allowed for eaching loading process. -r, --readahead limit(count) Set the readahead limit for worker processes preloading playlist contents. -T, --timeout timeout(seconds) Stop/kill a worker process if it fails to decode an image within a certain number of seconds. -x, --no-sysflt (build- option) aloadimage may be built with syscall filtering for worker processes. This may break image loading in some environ- ments/libc implementations and may therefore need to be disabled. -H, --vr attempt to connect as a VR compatible output, requires that the lis- tening end accepts HMD_L/R primary and secondary segment types. Playlist items should be prefixed with the intended dominant eye, e.g. l:image_l.jpg r:image_r.jpg. -h, --help Show a brief summary of commands and usage. ENVIRONMENT ARCAN_CONNPATH Name of the connection point to use when connecting to arcan. ARCAN_CONNKEY Key to use for authenticating againgst the connection path.
