White space is way too small for monospaced font #2533

Closed rebior closed 1 year ago

rebior commented 1 year ago

  1. Description I created vlw font files from the font "Noto Sans Mono" on Linux. The space character is excluded as mentioned in the guide. I use drawString to put smooth text on the screen and all characters have equal width except for space characters, that are way smaller.

  2. IDE: PlatformIO/Arduino

  3. TFT_eSPI library version: 2.5.0

  4. Board package esp32dev (cant't find exact version)

  5. Procesor ESP32

  6. TFT driver ST7735_BLACKTAB

  7. Interface type SPI

The following screenshot shows the two strings "HOST: " and " IP: ", both left aligned at the same x position. I would expect for the colons to be vertically aligned (which is the case if there are only characters other than space) Screenshot

I can also provide a vlw file if it helps.

The vlw files don't specify a space with, so this is guessed from the font height here: https://github.com/Bodmer/TFT_eSPI/blob/master/Extensions/Smooth_font.cpp#L139

In your use case gxadvance would probably work.

This means I should set that value manually after loading the font?

Bodmer commented 1 year ago

Yes.

The pull request (#2540) provides a simple and backwards compatible solution for that issue. I tested it in my setup and the alignment is perfect. Some details: I added an additional enumeration argument to the loadFont methods with default value set to current behavior. With this enum the user can select how the space width is computed.
