Could you please explain what you expect to see after saving a font file with this setting enabled?
I was having a go at producing a font starting with the picture in the following thread.
http://forum.high-logic.com:9080/t/creating-a-font-with-pictures-of-the-individual-letters/1380/1
I added six glyph positions at the end of a new font.
Into the first I put the result of importing the picture.
I then copied that into the other five.
For each in turn I deleted 4 rows of contours and moved the remaining line down so that the letters all sat on a base line of 0 vertically.
I then copied each of the five glyphs many times, placing the copies in the glyphs for the letters of which it contained the design.
So, for example, the third of the six extra glyphs, containing the second row, was copied eighteen times into each of S to A and 0 to 9.
I then went through all of the glyphs for the capitals A to Z, lowercase a to z and the digits and punctuation etc and deleted everything except the contours for one character from each glyph.
So, for example, in the glyph for U the contours for S to T and V to 0 were deleted.
Thus I had a font with only the contours for the appropriate character in each used position, correctly aligned vertically, yet with widely different offsets, when I needed them all to be zero.
For example, U had glyph metrics of Left Side Bearing of -3537 and Advance Width of 768.
The glyph information panel does, however, have White space before character: -3537 (x = 0) so maybe that x = 0 is the clue to what is happening.
I tried moving one glyph manually and it took a time, so I tried the glyph transformer to set the left side bearing to 0, yet it did not seem to do anything.
So I asked in the forum.
Some time later I started trying the Tools | AutoMetrics… in case that could do it and it produced the correct result. I cannot remember exactly what I did, which is ironic as I usually make detailed notes of what I do as I go along, however, it was late and I was just trying Tools | AutoMetrics before finishing.
Yet I still do not understand why the glyph transformer did not do what I expected.
I feel that I am missing something and hope that I can learn what it is so that I can understand what is happening.
