When rotating, the origin point (0,0) changes — the idea is that it should be arranged at the top-left of the display for the other graphics functions to make consistent sense (and match all the function descriptions above). And in the example above, the yOffset would be negative, this is the offset from the current cursor position to the top of the bitmap to be drawn. These last four values will then contain the upper-left corner and the width & height of the area covered by this text — these can then be passed directly as arguments to fillRect(). size=2 will render the text at 10x16 pixels per character). One of these lines may vary from one example to the next, depending which display hardware it’s written to support. The latest update to the Adafruit_GFX Arduino library now includes support for proportionally-spaced bitmap fonts of various sizes and styles. For security reasons, an e-mail has been sent to you acknowledging your subscription. If this happens, use fewer or smaller fonts, or use the standard built-in font. The name assigned to the font structure within this file is based on the input filename and font size, not the output. Then the .h filename and font structure name can match. You can place this character at any location and with any color. If this happens, use fewer or smaller fonts, or use the standard built-in font. Arduino Mega or any 32-bit board should manage fine. The xAdvance value gives the number of pixels the cursor should be advanced after drawing a character. updated on Jul 29, 2012. drawRect() renders just the frame (outline) of the rectangle — the interior is unaffected — while fillRect() fills the entire area with a given color: To create a solid rectangle with a contrasting outline, use fillRect() first, then drawRect() over it. Initially this is set to (0,0) (the top-left corner of the screen). This is why I recommend using descriptive filenames incorporating the font base name, size, and "7p". This will be flicker-free but requires more RAM (about 512 bytes for the 128x32 pixel canvas shown above), so it’s not always practical on AVR boards with only 2K. From the Arduino “Sketch” menu, select “Include Library” then “Manage Libraries…”. The syntax for using this library (and the separate installation above) are admittedly a bit peculiar…it’s a side-effect of the way Arduino handles libraries. Building this tool requires the gcc compiler and FreeType library. An X and Y coordinate where the top-left corner of the image is positioned (this doesn’t need to be within screen bounds…the library will clip the image as it’s loaded). For most fonts this would be 32, which corresponds to the space character. Arduino Mega or any 32-bit board should manage fine.
