Re: convert line height value from pixel to pt

2001-11-22 Thread Peter B. West

lpkhoo,

Just on the point of pixel conversion - there is no rigorously defined 
value for pixel.  The FOP code assumes 1 point per pixel, but the actual 
size is up to the implementation and the medium, and may vary in the 
vertical and horizontal directions.  Users are warned in the spec 
against relying on pixels, which may be a minimum of 1 device unit 
(which will vary from output device to device), 1/72 (i.e. a point), 
1/90 or 1/92.  Don't use them.

 The line height is converted into points the same way that all other 
 units are converted.
 The problem is that the actual line height in the output is incorrect. 
 It sets the line height to the lineheight - half leading (depends on the 
 font) which is wrong. The line stacking is not done correctly anyway so 
 it is not simple to fix it properly.

 hello,

 Anyone know how to convert line height value, I need to convert the value
 from pixel to pt.

 I try to convert the value from pixel by multiple 0.75 (value * 0.75) ,

 When I run FOP 0.20.0,  I found the line height is wrong.

 So, I not sure how to convert the value from pixel to pt, anyone know how
 to calculate?


 Thank you.

 lpkhoo.
