This usually means that: your font texture wasn't uploaded into GPU, or your shader or other rendering state are not reading from the right texture (e.g. texture wasn't bound).
If this happens using the standard back-ends it is probably that the texture failed to upload, which could happens if for some reason your texture is too big. Also see [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md).

# Q&A: Fonts, Text
### Q: How should I handle DPI in my application?
The short answer is: obtain the desired DPI scale, load a suitable font resized with that scale (always round down font size to nearest integer), and scale your Style structure accordingly using `style.ScaleAllSizes()`.
Your application may want to detect DPI change and reload the font and reset style being frames.
Your ui code should avoid using hardcoded constants for size and positioning. Prefer to express values as multiple of reference values such as `ImGui::GetFontSize()` or `ImGui::GetFrameHeight()`. So e.g. instead of seeing a hardcoded height of 500 for a given item/window, you may want to use `30*ImGui::GetFontSize()` instead.
Down the line Dear ImGui will provide a variety of standardized reference values to facilitate using this.
Applications in the `examples/` folder are not DPI aware partly because they are unable to load a custom font from the file-system (may change that in the future).
The reason DPI is not auto-magically solved in stock examples is that we don't yet have a satisfying solution for the "multi-dpi" problem (using the `docking` branch: when multiple viewport windows are over multiple monitors using different DPI scale). The current way to handle this on the application side is:
- Create and maintain one font atlas per active DPI scale (e.g. by iterating `platform_io.Monitors[]` before `NewFrame()`).
- Hook `platform_io.OnChangedViewport()` to detect when a `Begin()` call makes a Dear ImGui window change monitor (and therefore DPI).
- In the hook: swap atlas, swap style with correctly sized one, remap the current font from one atlas to the other (may need to maintain a remapping table of your fonts at variying DPI scale).
This approach is relatively easy and functional but come with two issues:
- It's not possibly to reliably size or position a window ahead of `Begin()` without knowing on which monitor it'll land.
- Style override may be lost during the `Begin()` call crossing monitor boundaries. You may need to do some custom scaling mumbo-jumbo if you want your `OnChangedViewport()` handler to preserve style overrides.
Please note that if you are not using multi-viewports with multi-monitors using different DPI scale, you can ignore all of this and use the simpler technique recommended at the top.
### Q: How can I load a different font than the default?
Use the font atlas to load the TTF/OTF file you want:
(You may browse this document at https://github.com/ocornut/imgui/blob/master/docs/FONTS.md or view this file with any Markdown viewer.)
The code in imgui.cpp embeds a copy of 'ProggyClean.ttf' (by Tristan Grimmer),
a 13 pixels high, pixel-perfect font used by default. We embed it in the source code so you can use Dear ImGui without any file system access. ProggyClean does not scale smoothly, therefore it is recommended that you load your own file when using Dear ImGui in an application aiming to look nice and wanting to support multiple resolutions.
You may also load external .TTF/.OTF files.
In the [misc/fonts/](https://github.com/ocornut/imgui/tree/master/misc/fonts) folder you can find a few suggested fonts, provided as a convenience.
**Read the FAQ:** https://www.dearimgui.org/faq (there is a Fonts section!)

---------------------------------------
## Readme First
- All loaded fonts glyphs are rendered into a single texture atlas ahead of time. Calling either of `io.Fonts->GetTexDataAsAlpha8()`, `io.Fonts->GetTexDataAsRGBA32()` or `io.Fonts->Build()` will build the atlas.
- You can use the style editor `ImGui::ShowStyleEditor()` in the "Fonts" section to browse your fonts and understand what's going on if you have an issue. You can also reach it in `Demo->Tools->Style Editor->Fonts`:
If you get an assert stating "Could not load font file!", your font filename is likely incorrect. Read "[About filenames](#about-filenames)" carefully.
<br>_(settings: Dark style (left), Light style (right) / Font: NotoSansCJKjp-Medium, 20px / Rounding: 5)_
**Offset font vertically by altering the `io.Font->DisplayOffset` value:**
```cpp
ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
font->DisplayOffset.y = 1; // Render 1 pixel down
```
**Font Atlas too large?**
- If you have very large number of glyphs or multiple fonts, the texture may become too big for your graphics API. The typical result of failing to upload a texture is if every glyphs appears as white rectangles.
- In particular, using a large range such as `GetGlyphRangesChineseSimplifiedCommon()` is not recommended unless you set `OversampleH`/`OversampleV` to 1 and use a small font size.
- Mind the fact that some graphics drivers have texture size limitation.
- If you are building a PC application, mind the fact that your users may use hardware with lower limitations than yours.
Some solutions:
1. Reduce glyphs ranges by calculating them from source localization data.
You can use the `ImFontGlyphRangesBuilder` for this purpose, this will be the biggest win!
2. You may reduce oversampling, e.g. `font_config.OversampleH = font_config.OversampleV = 1`, this will largely reduce your texture size.
3. Set `io.Fonts.TexDesiredWidth` to specify a texture width to minimize texture height (see comment in `ImFontAtlas::Build()` function).
4. Set `io.Fonts.Flags |= ImFontAtlasFlags_NoPowerOfTwoHeight;` to disable rounding the texture height to the next power of two.
5. Read about oversampling [here](https://github.com/nothings/stb/blob/master/tests/oversample).

## Using Icons
Using an icon font (such as [FontAwesome](http://fontawesome.io) or [OpenFontIcons](https://github.com/traverseda/OpenFontIcons)) is an easy and practical way to use icons in your Dear ImGui application.
A common pattern is to merge the icon font within your main font, so you can embed icons directly from your strings without having to change fonts back and forth.
To refer to the icon UTF-8 codepoints from your C++ code, you may use those headers files created by Juliette Foucaut: https://github.com/juliettef/IconFontCppHeaders.
So you can use `ICON_FA_SEARCH` as a string that will render as a "Search" icon.
Example Setup:
```cpp
// Merge icons into default tool font
#include "IconsFontAwesome.h"
ImGuiIO& io = ImGui::GetIO();
io.Fonts->AddFontDefault();
ImFontConfig config;
config.MergeMode = true;
config.GlyphMinAdvanceX = 13.0f; // Use if you want to make the icon monospaced
- Dear ImGui uses imstb\_truetype.h to rasterize fonts (with optional oversampling). This technique and its implementation are not ideal for fonts rendered at small sizes, which may appear a little blurry or hard to read.
- There is an implementation of the ImFontAtlas builder using FreeType that you can use in the [misc/freetype/](https://github.com/ocornut/imgui/tree/master/misc/freetype) folder.
- FreeType supports auto-hinting which tends to improve the readability of small fonts.
- Read documentation in the [misc/freetype/](https://github.com/ocornut/imgui/tree/master/misc/freetype) folder.
- Correct sRGB space blending will have an important effect on your font rendering quality.

## Using Custom Glyph Ranges
You can use the `ImFontGlyphRangesBuilder` helper to create glyph ranges based on text input. For example: for a game where your script is known, if you can feed your entire script to it and only build the characters the game needs.
io.Fonts->Build(); // Build the atlas while 'ranges' is still in scope and not deleted.
```
##### [Return to Index](#index)
## Using Custom Colorful Icons
**(This is a BETA api, use if you are familiar with dear imgui and with your rendering back-end)**
- You can use the `ImFontAtlas::AddCustomRect()` and `ImFontAtlas::AddCustomRectFontGlyph()` api to register rectangles that will be packed into the font atlas texture. Register them before building the atlas, then call Build()`.
- You can then use `ImFontAtlas::GetCustomRectByIndex(int)` to query the position/size of your rectangle within the texture, and blit/copy any graphics data of your choice into those rectangles.
- This API is beta because it is likely to change in order to support multi-dpi (multiple viewports on multiple monitors with varying DPI scale).
#### Pseudo-code:
```cpp
// Add font, then register two custom 13x13 rectangles mapped to glyph 'a' and 'b' of this font
- Compile and use [binary_to_compressed_c.cpp](https://github.com/ocornut/imgui/blob/master/misc/fonts/binary_to_compressed_c.cpp) to create a compressed C style array that you can embed in source code.
- See the documentation in [binary_to_compressed_c.cpp](https://github.com/ocornut/imgui/blob/master/misc/fonts/binary_to_compressed_c.cpp) for instruction on how to use the tool.
- You may find a precompiled version binary_to_compressed_c.exe for Windows instead of demo binaries package (see [README](https://github.com/ocornut/imgui/blob/master/docs/README.md)).
- The tool can optionally output Base85 encoding to reduce the size of _source code_ but the read-only arrays in the actual binary will be about 20% bigger.
Then load the font with:
```cpp
ImFont* font = io.Fonts->AddFontFromMemoryCompressedTTF(compressed_data, compressed_data_size, size_pixels, ...);
```
or
```cpp
ImFont* font = io.Fonts->AddFontFromMemoryCompressedBase85TTF(compressed_data_base85, size_pixels, ...);
```

## About filenames
**Please note that many new C/C++ users have issues their files _because the filename they provide is wrong_.**
Two things to watch for:
- Make sure your IDE/debugger settings starts your executable from the right working directory. In Visual Studio you can change your working directory in project `Properties > General > Debugging > Working Directory`. People assume that their execution will start from the root folder of the project, where by default it oftens start from the folder where object or executable files are stored.
```cpp
// Relative filename depends on your Working Directory when running your program!
- In C/C++ and most programming languages if you want to use a backslash `\` within a string literal, you need to write it double backslash `\\`. At it happens, Windows uses backslashes as a path separator, so be mindful.
```cpp
io.Fonts->AddFontFromFileTTF("MyFiles\MyImage01.jpg", ...); // This is INCORRECT!!
io.Fonts->AddFontFromFileTTF("MyFiles\\MyImage01.jpg", ...); // This is CORRECT
```
In some situations, you may also use `/` path separator under Windows.

It is less error prone (less code and less bugs) than traditional retained-mode interfaces, and lends itself to create dynamic user interfaces.

**Which version should I get?**
I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported.

I first discovered the IMGUI paradigm at [Q-Games](http://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it.

- You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.
- Then build using `make` while in the `example_emscripten/` directory.
- Note that Emscripten 1.39.0 (October 2019) obsoleted the `BINARYEN_TRAP_MODE=clamp` compilation flag which was required with version older than 1.39.0 to avoid rendering artefacts. See [#2877](https://github.com/ocornut/imgui/issues/2877) for details. If you use an older version, uncomment this line in the Makefile:
## How to Run
To run on a local machine:
- Generally you may need a local webserver. Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-xhr) requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a [local webserver](https://emscripten.org/docs/getting_started/FAQ.html#faq-local-webserver) and then open http://localhost:8000/hello.html."_
- Emscripten SDK has a handy `emrun` command: `emrun example_emscripten.html` which will spawn a temporary local webserver. See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
- Otherwise you may use Python builtin webserver: `python -m http.server` in Python 3 or `python -m SimpleHTTPServer` in Python 2. After doing that, you can visit http://localhost:8000/.
## Obsolete features:
`#EMS += -s BINARYEN_TRAP_MODE=clamp`
- Emscripten 2.0 (August 2020) obsoleted the fastcomp back-end, only llvm is supported.
- Emscripten 1.39.0 (October 2019) obsoleted the `BINARYEN_TRAP_MODE=clamp` compilation flag which was required with version older than 1.39.0 to avoid rendering artefacts. See [#2877](https://github.com/ocornut/imgui/issues/2877) for details. If you use an older version, uncomment this line in the Makefile: `#EMS += -s BINARYEN_TRAP_MODE=clamp`

// - v0.61: (2019/01/15) added support for imgui allocators + added FreeType only override function SetAllocatorFunctions().
// - v0.62: (2019/02/09) added RasterizerFlags::Monochrome flag to disable font anti-aliasing (combine with ::MonoHinting for best results!)
