Gettextbounds library. Refer to the sketch I've included. g. From the Arduino “Sketch” menu, select “Include Library,” then “Manage Libraries…” In the Arduino Library Manager window, search for a display’s driver type (e. Jul 29, 2012 · The Adafruit_GFX library for Arduino provides a common syntax and set of graphics functions for all of our LCD and OLED displays and LED matrices. print("x1:"); Serial. zip. Jun 14, 2024 · Adafruit_GFX always works together with an additional library unique to each specific display type. println(x1); Serial. Jan 8, 2013 · First up I've concluded that the getTextBounds function includes an additional character. getTextBounds(power_output, 0, 0, &x1, &y1, &w, &h); Serial. I want to print a text line, centered horizontally, on the ILI9341 display. Jan 22, 2024 · I am using an ESP32 uProcessor to drive an MSP2807, ILI9341, 240 x 320 display using the Adafruit_GFX and Adafruit_ILI9341 libraries. In short, getTextBounds is to get the RECT of the exact text. Its possible to set function like "setCenter" for X,Y coordinates? (One time I set X,Y , then only "setCenter" for X,Y. getTextBounds_Issue_example_002. Feb 11, 2018 · getTextBounds expects a string, a starting cursor X&Y position (the current cursor position will not be altered), and addresses of two signed and two unsigned 16-bit integers. println(y1); Jul 29, 2012 · The Adafruit_GFX library for Arduino provides a common syntax and set of graphics functions for all of our LCD and OLED displays. These can be installed using the Arduino Library Manager. Pass string and a cursor position, returns UL corner and W,H. I'm running into an annoying issue with the Adafruit_GFX library; when I run display. getTextBounds("AQUAMATIC STATUS", x, y, &x1, &y1, &w, &h); w returns 124, which I think is incorrect. Jan 8, 2013 · getTextBounds (const __FlashStringHelper *s, int16_t x, int16_t y, int16_t *x1, int16_t *y1, uint16_t *w, uint16_t *h) Helper to determine size of a PROGMEM string with current font/size. The unknown character I am guessing is the termination character /0 of the char array. Jul 29, 2012 · Use getTextBounds() to determine the smallest rectangle encompassing a string, erase the area using fillRect(), then draw new text: Jan 8, 2013 · getTextBounds (const char *string, int16_t x, int16_t y, int16_t *x1, int16_t *y1, uint16_t *w, uint16_t *h) Helper to determine size of a string with current font/size. Letters are 5+1 wide, and the string has 16 chars, so shouldn't w be 95, since it should return the total box width -1? Jul 29, 2012 · Use getTextBounds() to determine the smallest rectangle encompassing a string, erase the area using fillRect(), then draw new text: Jan 8, 2013 · getTextBounds (const char *string, int16_t x, int16_t y, int16_t *x1, int16_t *y1, uint16_t *w, uint16_t *h) Helper to determine size of a string with current font/size. This allows Arduino sketches to easily be adapted between display types with minimal fuss…and any new features, performance improvements and bug fixes will immediately apply across our complete offering of color displays. print("y1:"); Serial. The different between getTextBounds and measureText is described with the image below. int16_t x1, y1; uint16_t w, h; display. . Oct 25, 2019 · Hello. The measureText is the length of the text, including the extra gap on the left and right. If I execute getTextBounds where my text is "Hello" the width is 60 but i expect 50. I have 2,42" OLED display with Adafruit library. For example, now I have 6 different text: ONE TWO THREE FOUR FIVE SIX some of them have different number of lettetrs, and I need to put different X,Y coordinates (6 times) to have all text in one position, center. Jan 15, 2017 · pLCD->setTextWrap(m_bWrap); pLCD->setFont(m_pFont); int16_t nX = 0, nY = 0; uint16_t nWidth = 0, nHeight = 0; pLCD->getTextBounds(m_strText, 0, 0, &nX, &nY, &nWidth, &nHeight); If m_nFontSize = 1, m_pFont = NULL, m_strText = "Irrigation controller settings" and m_bWrap = false then why would getTextBounds () be returning 65535 as the width Dec 8, 2013 · power_output += "W"; // Get the size of the bounding box to erase the old text. Jul 29, 2012 · Use getTextBounds() to determine the smallest rectangle encompassing a string, erase the area using fillRect(), then draw new text: Jan 8, 2013 · getTextBounds (const char *string, int16_t x, int16_t y, int16_t *x1, int16_t *y1, uint16_t *w, uint16_t *h) Helper to determine size of a string with current font/size. vphw lwxgwzv pimy lfapx xtul vgdoig fosr fsefbhhk oufbo cde
