- * The GTF EXCEL(TM) SPREADSHEET, a sample (and the definitive)

- *
- * ftp://ftp.vesa.org/pub/GTF/GTF_V1R1.xls
- *
- *
- *
- * This program takes a desired resolution and vertical refresh rate,
- * and computes mode timings according to the GTF Timing Standard.
- * These mode timings can then be formatted as an XServer modeline
- * or a mode description for use by fbset(8).
- *
- *
- *
- * NOTES:
- *
- * The GTF allows for computation of "margins" (the visible border
- * surrounding the addressable video); on most non-overscan type
- * systems, the margin period is zero. I've implemented the margin
- * computations but not enabled it because 1) I don't really have
- * any experience with this, and 2) neither XServer modelines nor
- * fbset fb.modes provide an obvious way for margin timings to be
- * included in their mode descriptions (needs more investigation).
- *
- * The GTF provides for computation of interlaced mode timings;
- * I've implemented the computations but not enabled them, yet.
- * I should probably enable and test this at some point.
- *
- *
- *
- * TODO:
- *
- * o Add support for interlaced modes.
- *
- * o Implement the other portions of the GTF: compute mode timings
- * given either the desired pixel clock or the desired horizontal
- * frequency.
- *
- * o It would be nice if this were more general purpose to do things
- * outside the scope of the GTF: like generate double scan mode
- * timings, for example.
- *
- * o Printing digits to the right of the decimal point when the
- * digits are 0 annoys me.
- *
- * o Error checking.

+ *
+ *
+ *
+ * This program takes a desired resolution and vertical refresh rate,
+ * and computes mode timings according to the GTF Timing Standard.
+ * These mode timings can then be formatted as an XServer modeline
+ * or a mode description for use by fbset(8).
+ *
+ *
+ *
+ * NOTES:
+ *
+ * The GTF allows for computation of "margins" (the visible border
+ * surrounding the addressable video); on most non-overscan type
+ * systems, the margin period is zero. I've implemented the margin
+ * computations but not enabled it because 1) I don't really have
+ * any experience with this, and 2) neither XServer modelines nor
+ * fbset fb.modes provide an obvious way for margin timings to be
+ * included in their mode descriptions (needs more investigation).
+ *
+ * The GTF provides for computation of interlaced mode timings;
+ * I've implemented the computations but not enabled them, yet.
+ * I should probably enable and test this at some point.
+ *
+ *
+ *
+ * TODO:
+ *
+ * o Add support for interlaced modes.
+ *
+ * o Implement the other portions of the GTF: compute mode timings
+ * given either the desired pixel clock or the desired horizontal
+ * frequency.
+ *
+ * o It would be nice if this were more general purpose to do things
+ * outside the scope of the GTF: like generate double scan mode
+ * timings, for example.
+ *
+ * o Printing digits to the right of the decimal point when the
+ * digits are 0 annoys me.
+ *
+ * o Error checking.
