typedef struct RotatedTextItemTemplate_t | RotatedTextItem_t |
Functions | |
static XImage * | MakeXImage (Display *dpy, int w, int h) |
Create an XImage structure and allocate memory for it. | |

Routine to mimic ‘strdup()’ (some machines don't have it) | |
static char * | my_strtok (char *str1, char *str2) |
Routine to replace ‘strtok’ : this one returns a zero length string if it encounters two consecutive delimiters. | |
static void | XRotAddToLinkedList (Display *dpy, RotatedTextItem_t *item) |
Adds a text item to the end of the cache, removing as many items from the front as required to keep cache size below limit. | |

Create a rotated text item. | |
int | XRotDrawAlignedImageString (Display *dpy, XFontStruct *font, float angle, Drawable drawable, GC gc, int x, int y, char *text, int align) |

static RotatedTextItem_t * | XRotRetrieveFromCache (Display *dpy, XFontStruct *font, float angle, char *text, int align) |
Query cache for a match with this font/text/angle/alignment request, otherwise arrange for its creation. | |
void | XRotSetBoundingBoxPad (int p) |
Set the padding used when calculating bounding boxes. | |
void | XRotSetMagnification (float m) |
Set the font magnification factor for all subsequent operations. | |
XPoint * | XRotTextExtents (Display *, XFontStruct *font, float angle, int x, int y, char *text, int align) |
Calculate the bounding box some text will have when painted. | |
float | XRotVersion (char *str, int n) |
Return version/copyright information. | |
