Re: Generating ppt through java
Hi Yegor, I need to read text in the cells (in the form of string) from an Excel 2007 file. I am using the package org.apache.poi.ss.usermodel.*. I tried to use the methods Cell.getRichStringCellValue().getString() and Cell.getRichStringCellValue().toString(). But these methods are returning null, when the cell's text is having different fonts (i.e. some part of the cell's text is bold and some part is plain). Is there any way I can get the plain text regardless of the font and format of the text ?

Re: Generating ppt through java
Hi Yegor,
The following method in PPGrapics2D is not implemented in the latest source
code in hslf.
Whether it is going to be implemented shortly ? The method paint() in
TextPainter class uses this method.
Is there any alternate way to display the text if we have corresponding
AttributedCharacterIterator and coordinates like below ?
public void drawString(AttributedCharacterIterator iterator, float x,
float y) {
log.log(POILogger.WARN, Not implemented);
}
Regards,
Dinakara

Generating ppt through java
I am trying to generate ppt through Java using Apache POI API. I am able to create table, bulletted text etc using this API. Please answer the following two questions, if anyone aware of this. 1. How to split text across two slides, if the row had to be broken across 2 slides because the row is so big that it can only be accomodated in 2 slide ? 2. How to resize table cell , if the text which is going to put in that cell is larger than table cell size ? -- View this message in context: http://www.nabble.com/Generating-ppt-through-java-tp18399673p18399673.html Sent from the POI - Dev mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Generating ppt through java
Thanks for the reply. Suppose I have some data and I want to put into some table cell, then how to calculate the table cell size (i.e. height or width) required. If the text is to be bold or font need to be changed then how to calculate the new height and width of the table cell ? dinshetty wrote: I am trying to generate ppt through Java using Apache POI API.

Re: Generating ppt through java
Hi, suppose I have some 9 rows of text. How can we find that only these many rows can be put into one slide and remaining can be put into another slide. i.e. How can we calculate that one slide can hold this much text. How can we calculate in the below cases ? 1. if we change font and make it bold etc) ? 2. if the alignment of the text is changed ? dinshetty wrote: I am trying to generate ppt through Java using Apache POI API.
