💖 rendercheck(1) 💖

okay so bestie, welcome to the General Commands Manual for rendercheck, and no I'm not kidding, this one is genuinely iconic for a very specific type of girlie (that type being: X Server Render implementation authors). sit down, grab a boba 🧋, and let's get into it.

✨ NAME ✨

rendercheck — simple tests of the X Render extension. that's it, that's the whole vibe 💅

🦋 SYNOPSIS 🦋

rendercheck [-d|--display display] [-i|--iter] [--sync] [-t|--tests test1,test2,test3,...] [-o|--ops op1,op2,op3,...]
[-v|--verbose] [--minimalrendering]

🌸 DESCRIPTION 🌸

so rendercheck is a set of simple tests of the X Render extension. lowkey humble of it, honestly. and who is it for? it's literally designed for authors of Render implementations in X Servers. if that's you, this is your main character moment 👑

🎀 OPTIONS 🎀

okay this is the part where we list EVERYTHING, no skipping, no gatekeeping 🫶

  • -d|--display display — tells it which display to test against. yes, exactly that display. pick your fave.
  • -i|--iter iterations — how many times to repeat each operation before it samples results. and why would you want that? because some X Servers lowkey act different (hardware vs software rendering paths) depending on what operations happened before, so this is your little lever to influence the server's choices. it's giving puppeteer energy 🧚
  • --sync — enables synchronous xlib operation, for debugging. debugging besties rise 🙈
  • -t|--tests test1,test2,test3... — turns on only a specific subset of the possible tests. the test names are: fill, dcoords, scoords, mcoords, tscoords, tmcoords, blend, composite, cacomposite, gradients, repeat, triangles, and bug7366. names must be separated by commas and have no spaces. not one. zero. periodt.
  • -f|--formats format1,format2,format3... — turns on only a specific subset of the possible formats. heads up though: only formats listed in the server-supported format list are actually available. names must be separated by commas and have no spaces.
  • -o|--ops — turns on only a specific subset of the Render operators.
  • -v|--verbose — enables verbose printing of information on tests run, and on successes and failures. she's chatty and we love her for it 💬
  • --minimalrendering — disables copying of offscreen destinations to the window. that copying is on by default, and it exists purely to give you, the user, visual feedback. so yeah, --minimalrendering means less to look at, more to compute.

💀 BUGS 💀

ngl there are several limitations, and they're documented in the TODO file that accompanies the source. if you find more bugs (and you might 😭), please report them to http://bugs.freedesktop.org/. do your civic duty, bestie.

and that's a wrap! this page came to you from X Version 11, and it's rendercheck version 1.5, living its best life in the General Commands Manual section. go test those Render implementations, queen 💜✨🦋
