General questions
What is Krita?
--------------
This is our vision for the development of Krita:
Krita is a free and open source cross-platform application that
offers an end-to-end solution for creating digital art files from
scratch. Krita is optimized for frequent, prolonged and focused use.
Explicitly supported fields of painting are illustrations, concept
art, matte painting, textures, comics and animations.
Developed together with users, Krita is an application that supports
their actual needs and workflow. Krita supports open standards and
interoperates with other applications
Krita starts with an empty canvas and nothing changes when you try to draw or Krita shows a black or blank screen or Krita crashes when creating a document or Krita's menubar is hidden on a Windows system with an Intel GPU
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
* Update to Krita 3.3 or later:
* Go to Settings/Configure Krita/Display, change Renderer to ANGLE and restart Krita. If this doesn't work, disable Canvas Graphics Acceleration and please also make a bug report about it.
Krita freezes when saving to PNG or JPEG on OSX or macOS/ I cannot enable OpenGL on my mac
------------------------------------------------------------------------------------------
If the former, you probably have an AMD Radeon display chip and are
running a version of Krita lower than 3.2. Disable opengl in Krita. If
the latter, you've still got an AMD display chip in your mac and are
running Krita 3.2 or 3.3. The problem is that Apple's AMD opengl drivers
hang Krita 3.x when trying to save to a single-layer file format. No, we
don' t know why, and we don't have the hardware to figure out why. But
Krita 4.0, this problem has been solved because there Krita saves a copy
of the image in the background.
Is it possible to use Krita in my own language, not English?
------------------------------------------------------------
Unless you belong to a proud tribe of a minority language, YES it is
POSSIBLE! You can easily do this by going into
#. settings switch application language. An small window will appear.
#. click Primary language and select your language.
#. click OK to close the window.
#. restart krita and it will be displayed in your selected language!
Does Krita have layer clip or clipping mask?
--------------------------------------------
Krita has no clipping mask, but it has a clipping feature called
inherit alpha. Let's see :ref:`this page <clipping_masks_and_alpha_inheritance>` and learn how to do
clipping in Krita!
OBS can't record the Krita openGL canvas
----------------------------------------
Apparantly the workaround for this is to either...
#. Turn off OpenGL in settings configure Krita display.
#. Or don't use the hardware accelerated mode(game recording mode) in
OBS, so capture the whole desktop instead of attempting to capture
only Krita.
*For Krita 3.3 or later:* You might be able to work around by using the
ANGLE renderer instead of native OpenGL.
Where are the configuration files stored?
-----------------------------------------
These are stored at the following places for the following operating
systems:
Linux
:file:`$HOME/.config/kritarc`
Windows
:file:`%APPDATA%\Local\kritarc`
MacOS X
:file:`$HOME/Library/Preferences/kritarc`
The kritarc file is the configuration file.
My resource disappeared with installing 3.0! Did Krita delete them?
-------------------------------------------------------------------
Don't worry, Krita nor the installer know how to delete your
brushes(unless you use the 'delete backup files' in the resource
manager)
Your old 2.9 brushes should be at
Linux
:file:`home/.kde/share/krita`
Windows
:file:`User\\AppData\\Roaming\\krita\\share\\apps\\krita\\`
For 3.0, these should go to
Linux
:file:`$HOME/.local/share/krita/`
Windows
:file:`user\\Appdata\\Roaming\\krita\\` or :file:`%APPDATA%\\Roaming\\krita\\`
OSX
:file:`~/Library/Application Support/Krita/`
Just copy the files over!
Resetting Krita configuration
-----------------------------
You can reset the Krita configuration in two ways:
- For Krita 3.0 and later: Delete/rename the kritarc file, found here:
Linux
:file:`$HOME/.config/kritarc`
Windows
:file:`%APPDATA%\\Local\\kritarc`
MacOS X
:file:`$HOME/Library/Preferences/kritarc`
There can be two other files you might want to remove: kritaopenglrc and
kritadisplayrc.
If the config was causing a crash, don't delete but instead rename and
send us the file so we can figure out what caused the crash.
Krita tells me it can't find the configuration files and then closes, what should I do?
---------------------------------------------------------------------------------------
First, search your filesystem for kritarc. If it's nowhere to be found,
then that is the main problem.
Causes for this could be the following:
- It might be that your download got corrupted and is missing
files(common with bad wifi and bad internet connection in general),
in that case, try to find a better internet connection before trying
to download again. Krita should be around 80 to 100 mb big when
downloading.
- It might be something went wrong during installation. Check if your
harddrive isn't full. If not, and the problem still occurs, there
might be something odd going on with your device and it's recommended
to find an computer expert to diagnose what is going on.
- Some unzippers don't unpack our zipfiles correctly. The native ones
on windows, OSX and most linux distributions should be just fine, and
we recommend using them.
What Graphics Cards does Krita support?
---------------------------------------
Krita can use OpenGL to accelerate painting and canvas zooming, rotation
and panning. Nvidia and recent Intel GPUs give the best results. Make
sure your OpenGL drivers support OpenGL 3.2 as the minimum. AMD/ATI
GPUs are known to be troublesome, especially with the proprietary
drivers on Linux. However, it works perfectly with the radeon free
driver on linux for supported AMD GPU.
*For Krita 3.3 or later:* Krita on Windows can use Direct3D 11 for
graphics acceleration (through ANGLE).
I can't edit text from PSD files created by photoshop
-----------------------------------------------------
There is no text support for psd file yet. The text will appear
rasterized and converted into paint layer.
How much memory does my image take?
-----------------------------------
For simple images, that’s pretty simple: you mulitply width \* height \*
channels \* size of the channels (so, for a 1000×1000 16 bit integer
rgba image: 1000 x 1000 x 4 x 2). You multiply this by the number of
layers plus two (one for the image, one for the display). If you add
masks, filter layers or clone layers, it gets more complicated.
Why do I get a checkerboard pattern when I use the eraser?
----------------------------------------------------------
You’re probably used to Gimp or Photoshop. The background, that is
default or first layer in these applications doesn’t have an alpha
channel by default. so, on their background layer, the eraser paints in
the background color.
In Krita, all layers have an alpha channel, so if you want to paint in
the background color, you should do that, instead of erasing. You get
the same effect in, say, gimp, if you create new image, add an alpha
channel and then use the eraser tool. Most Krita users actually on
starting a sketch in Krita add a new blank layer first thing they do
(the INSert key is a useful shortcut here.) That doesn’t use extra
memory, since a blank layer or a layer with a default color just takes
one pixel worth of memory.
Can I use Krita with sandboxie on Windows?
------------------------------------------
No, this is not recommended. Sandboxie causes stuttering and freezes due
to the way it intercepts calls for resources on disk.
Can krita work with 8 bit (indexed) images?
-------------------------------------------
No. Krita has been designed from the ground up to use real colors, not
indexed palettes. There are no plans to support indexed color images,
though Krita can export to some indexed color image formats, such as
GIF. However, Krita does not offer detailed control over pixel values.
How do I export gifs with Krita?
--------------------------------
Currently, Krita 3.0 doesn't have gif, apng or spritesheet export yet.
Krita 3.1 does have :ref:`render_animation`.
For big projects we recommend exporting your animation as a png
sequence, and then inputtng that into a video editor.
How can I produce a backtrace on Windows?
