saving a canvas as an image

[Doctory]

Is it possible to save a canvas in a form of an image?
If so, how?

[Nixola]

canvas:getImageData():encode(filename)

[Doctory]

If you're using any version after 0.10, the function is called newImageData, not getImageData.

[dj--alex@ya.ru]

love.filesystem.setIdentity('realpath');
GAMEWINDOWCANVAS:newImageData():encode('png', realpath..levelname.. 'x2.png');


Thanks but
why it ignore realpath if i add it to filename?
realpath interpreted incorrect
/home/alex/.local/share/love/home/alex/Games/M2K/usr/bin/saves/m2ksavex

Im use 0.10.2 but Android packager limits me to 0.10.2 for forever.


i need to save files here
/home/alex/Документы/R-M2K/M2K_GAME_FOLDER/usr/bin/saves
image with savemage MUST be with folder with savegame...

and i get canvas image here
/home/alex/.local/share/love/m2k

no answer.
maybe this impossible direct save file to folder with game with lua commands.

Apart from the necro-posting you performed previously, yes, the encode function can only save to the save folder like literally all other löve related functions.

Also, forget about the realpath, you don't need to use it, it's already relative to the save folder.

GAMEWINDOWCANVAS:newImageData():encode('png', levelname.. 'x2.png')

That should do what you want... but then again, it's android, it may just not work at all.

We can move encoded (saved) image file by os.rename(src, dst)

to zorg
you don't understang
game already save game in special folder inside GAME folder,
i just want to save image with savegame folder.
i don't like ideology with "my documents" folder. good old games always do save in their folders.

to HDPLocust
for save game i use
file=love.filesystem.write(realfilename, data)
and it always works.


copy image from screenshot "zone" to destination - really no another methods?
i still hope, maybe found normal command like
canvas:saveimage(realpath,".png)...
i just need get png and redirect it as "data"
