## Dear ImGui: Using Fonts
(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. The files in this folder are suggested fonts, provided as a convenience.

---------------------------------------
## Readme First
- 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.
- Make sure your font ranges data are persistent (available during the call to GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build().
- 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`:
![imgui_capture_0008](https://user-images.githubusercontent.com/8225057/84162822-1a731f00-aa71-11ea-9b6b-89c2332aa161.png)
- Make sure your font ranges data are persistent (available during the calls to `GetTexDataAsAlpha8()`/`GetTexDataAsRGBA32()/`Build()`.
- Use C++11 u8"my text" syntax to encode literal strings as UTF-8. e.g.:
```
u8"hello"
u8"こんにちは" // this will be encoded as UTF-8
```
- If you want to include a backslash \ character in your string literal, you need to double them e.g. "folder\\\filename".
---------------------------------------
## 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
**The C++11 version of those files uses the u8"" utf-8 encoding syntax + \u**
` #define ICON_FA_SEARCH u8"\uf002" `
**The pre-C++11 version has the values directly encoded as utf-8:**
` #define ICON_FA_SEARCH "\xEF\x80\x82" `
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
static const ImWchar icon_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 };
io.Fonts->AddFontFromFileTTF("fonts/fontawesome-webfont.ttf", 13.0f, &config, icon_ranges);
u8"hello"
u8"こんにちは" // this will be encoded as UTF-8
```
Example Usage:
##### [Return to Index](#index)
## Font Loading Instructions
**Load default font:**
```cpp
// Usage, e.g.
ImGui::Text("%s among %d items", ICON_FA_SEARCH, count);
ImGui::Button(ICON_FA_SEARCH " Search");
// C string _literals_ can be concatenated at compilation time, e.g. "hello" " world"
// ICON_FA_SEARCH is defined as a string literal so this is the same as "A" "B" becoming "AB"
ImGuiIO& io = ImGui::GetIO();
io.Fonts->AddFontDefault();
```
See Links below for other icons fonts and related tools.
---------------------------------------
## Font Loading Instructions
Load default font:
**Load .TTF/.OTF file with:**
```cpp
ImGuiIO& io = ImGui::GetIO();
io.Fonts->AddFontDefault();
ImGuiIO& io = ImGui::GetIO();
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
```
Load .TTF/.OTF file with:
```cpp
ImGuiIO& io = ImGui::GetIO();
ImFont* font1 = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
ImFont* font2 = io.Fonts->AddFontFromFileTTF("anotherfont.otf", size_pixels);
If you get an assert stating "Could not load font file!", your font filename is likely incorrect. Read "[About filenames](#about-filenames)" carefully.
// Select font at runtime
ImGui::Text("Hello"); // use the default font (which is the first loaded font)
ImGui::PushFont(font2);
ImGui::Text("Hello with another font");
ImGui::PopFont();
```
For advanced options create a ImFontConfig structure and pass it to the AddFont function (it will be copied internally):
**Load multiple fonts:**
```cpp
ImFontConfig config;
config.OversampleH = 2;
config.OversampleV = 1;
config.GlyphExtraSpacing.x = 1.0f;
ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, &config);
```
**Read about oversampling [here](https://github.com/nothings/stb/blob/master/tests/oversample)**
ImGuiIO& io = ImGui::GetIO();
ImFont* font1 = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
ImFont* font2 = io.Fonts->AddFontFromFileTTF("anotherfont.otf", size_pixels);
- 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.
// Select font at runtime
ImGui::Text("Hello"); // use the default font (which is the first loaded font)
ImGui::PushFont(font2);
ImGui::Text("Hello with another font");
ImGui::PopFont();
```
**For advanced options create a ImFontConfig structure and pass it to the AddFont() function (it will be copied internally):**
```cpp
ImFontConfig config;
config.OversampleH = 2;
config.OversampleV = 1;
config.GlyphExtraSpacing.x = 1.0f;
ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, &config);
```
**Combine multiple fonts into one:**
```cpp
// Load a first font
ImFont* font = io.Fonts->AddFontDefault();
// Add character ranges and merge into the previous font
// The ranges array is not copied by the AddFont* functions and is used lazily
// so ensure it is available at the time of building or calling GetTexDataAsRGBA32().
static const ImWchar icons_ranges[] = { 0xf000, 0xf3ff, 0 }; // Will not be copied by AddFont* so keep in scope.
ImFontConfig config;
config.MergeMode = true;
io.Fonts->AddFontFromFileTTF("DroidSans.ttf", 18.0f, &config, io.Fonts->GetGlyphRangesJapanese()); // Merge into first font
io.Fonts->AddFontFromFileTTF("fontawesome-webfont.ttf", 18.0f, &config, icons_ranges); // Merge into first font
io.Fonts->Build();
```
**Add a fourth parameter to bake specific font ranges only:**
```cpp
// Basic Latin, Extended Latin
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesDefault());
// Default + Selection of 2500 Ideographs used by Simplified Chinese
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesChineseSimplifiedCommon());
// Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesJapanese());
```
See [Using Custom Glyph Ranges](#using-custom-glyph-ranges) section to create your own ranges.
**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 ImFontGlyphRangesBuilder for this purpose, this will be the biggest win!
2. You may reduce oversampling, e.g. config.OversampleH = 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.

## Freetype Rasterizer, Small Font Sizes
Here's an application using icons ("Avoyd", https://www.avoyd.com):
![avoyd](https://user-images.githubusercontent.com/8225057/81696852-c15d9e80-9464-11ea-9cab-2a4d4fc84396.jpg)
##### [Return to Index](#index)
## Using FreeType Rasterizer
- 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/ folder.
- 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.
**Note**
- This code currently creates textures that are unoptimally too large (could be fixed with some work).
- Also note that correct sRGB space blending will have an important effect on your font rendering quality.

## Using Custom Glyph Ranges
---------------------------------------
## Building 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.

## 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.
- 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:
```
// Add font, then register two custom 13x13 rectangles mapped to glyph 'a' and 'b' of this font
ImFont* font = io.Fonts->AddFontDefault();
int rect_ids[2];
rect_ids[0] = io.Fonts->AddCustomRectFontGlyph(font, 'a', 13, 13, 13+1);
rect_ids[1] = io.Fonts->AddCustomRectFontGlyph(font, 'b', 13, 13, 13+1);

## Embedding Fonts In Source Code
##### [Return to Index](#index)
- Compile and use '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 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).
## Using Font Data Embedded In Source Code
- 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:
` ImFont* font = io.Fonts->AddFontFromMemoryCompressedTTF(compressed_data, compressed_data_size, size_pixels, ...); `
```cpp
ImFont* font = io.Fonts->AddFontFromMemoryCompressedTTF(compressed_data, compressed_data_size, size_pixels, ...);
```
or
`ImFont* font = io.Fonts- AddFontFromMemoryCompressedBase85TTF(compressed_data_base85, size_pixels, ...);
`
```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!
io.Fonts->AddFontFromFileTTF("MyImage01.jpg", ...);
// Load from the parent folder of your Working Directory
io.Fonts->AddFontFromFileTTF("../MyImage01.jpg", ...);
```
- 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.
