APIers, This question was put to the forum without much luck getting an answer. I hope that someone who knows the API might also know more about the internal workings of OpenOffice and can explain this phenomenon before I have to resort to source code. Thanks.
Some information about the resolution used for XTextViewCursor.getPosition() would help. I can get the position of the cursor between two letters, but what is the resolution? Can I measure the width any more accurately than taking the cursor position left and right of a letter? See below... Keith I have written an extension that changes the colors of each letter in my document (for whatever reason). They each have a different color, or at least a color different than either of their neighbors. For example, they can alternate between red and black. When this runs for lines that are "tight" (have a very small amount of extra space before the margin), sometimes the word wrapping changes and the last word moves to the next line. Should this be happening? Why? I happen to be working with Windows but will now try to reproduce this on another platform. Perhaps someone can say if this theory is true. When there are no color changes between letters, a "run" of letters can be displayed or printed at once. The operating system can do this after being told coordinates of where to start. I'm not sure of the granularity of the coordinates, but it might be at the pixel. Some of the letters within the run might begin between pixels and use antialiasing or subpixels to be spaced just right. The operating system tells OpenOffice how long the run was, possibly rounded (up?) to the nearest pixel. OpenOffice then changes the color to red and draws the next character starting at some rounded or quantized pixel position. If these rounding errors accumulate, the line of text gets longer and the last word is forced off. Is this what happens? Is there any easy way to prevent it? --------------------------------------------------------------------- To unsubscribe, e-mail: api-unsubscr...@openoffice.apache.org For additional commands, e-mail: api-h...@openoffice.apache.org
