[HSLF] Bug 40143 - Font size
Hi List, any news about bug #40143 http://issues.apache.org/bugzilla/show_bug.cgi?id=40143? I'm experiencing the same problem described in some files. The font size returned is wrong, sometimes the correct information is being stored in other style like asian_or_complex, char_unknown_2 and even font.color. This is really annoying.

Re: PPT Unicode
Hi, I'm not changing the text. I just read it. My problem occurs when there is any TextCharsAtom because the platform I am using doesn't support Unicode, just ISO-8859-1. So I had to change the code replacing UTF-16LE by ISO-8859-1. So I think I have no way out but show the text, without styles. Thanks a lot, -- Tales Paiva Nick Burch wrote: On Tue, 5 Dec 2006, Tales Paiva Nogueira wrote: When PowerPoint stores text in Unicode a unknown char (byte value = 0) is placed between every normal char making the text 2 times longer than it really is. TextCharsAtoms, and other unicode containing fields in powerpoint files, are stored as UTF-16. That means two bytes are used to store every character. US-ASCII will be stored with the second byte zero, but other characters will need to make some use of the second byte. If you call getText() on a TextCharsAtom, it'll convert it to a string for you. You should really be using that, not getting the bytes directly. Is there any way to keep the style information and get the text as a TextByteAtom, instead of TextCharsAtom? Why? PowerPoint decided to make it a TextCharsAtom, rather than a TextByteAtom, since your string contained at least one character that couldn't be represented in a TextByteAtom. HSLF supports upgrading a TextByteAtom to a TextCharsAtom if you try to set text that can't be held in a TextByteAtom. It doesn't do the other way around. If you really want just the low order bytes, call getText() on the TextCharsAtom, and mangle the string yourself.

Unsupported features
Hi list, The questions I'm about to ask here are probably about non supported features by POI, but I'd like to get some hints to solve them even if I have to implement it. So Nick, Yegor and anyone who is working with POI, if you can give some directions I'll appreciate. 1. I'm trying to retrieve an image from the _pictures PictureData array. The problem I'm experiencing is in the case that the picture is a slide background because there isn't a Picture model object to get the corresponding image index in the array. 2. Another problem in the background issue is to get background colors. Every background has its color scheme or follows the master scheme, but when I change the background of a single slide, I can't get that color (that doesn't follows the master background). 3. I've already asked here about numbered lists, is there any flag that indicates if the list is numbered or bulleted? Some para_unknown field? 4. When there is a table in a ppt file and I resize it by the border lines, the anchor isn't updated. But when I change any column or row size, the anchor is updated, and I have the correct table size and position (anchor).

Re: Numbering formats of lines of text in PPT files

[HSLF] Indentation level identification
Hi,
I need to identify the indentation level of a text in a TextBox. For this
I created a method in the RichTextRun class as follows:
public int getTextOffset(){
return getParaTextPropVal(text.offset);
}
Assuming that the property name that holds this information is
text.offset, is it?
When I call it from my main class, it returns -1. I know this is because
the RichTextRun inherits the property from the Master.
Is there any other way to identify the indentation level for a given
RichTextRun?
Thanks a lot,
Tales Paiva

RE: TextBox bug
Hi,
I noticed this problem few days ago, I made a little change in the code,
and it worked properly for my needs. The change I made was add an test to
ensure that the _txtrun isn't null.
Below is the code for the setSheet(Sheet sheet) in the TextBox class:
public void setSheet(Sheet sheet){
_sheet = sheet;
//initialize _txtrun object.
//we can't do it in the constructor because the sheet is not
assigned yet
if(_txtrun == null) initTextRun();
if (_txtrun != null){
RichTextRun[] rt = _txtrun.getRichTextRuns();
for (int i = 0; i rt.length; i++) {
rt[i].supplySlideShow(_sheet.getSlideShow());
}
if (_fontname != null) {
setFontName(_fontname);
_fontname = null;
}
}
}
I hope it can help you.

I have an instance of Slide, and I call the getShapes() method (some of
the shapes are TextBox instances)

When you create a TextBox, it does create and set _txtrun (line 160 in
createSpContainer), so I'm not sure where your problem is?
Could you supply the code you use to generate the NullPointerExceptions?

RE: TextBox bug
This piece of code doesn't work in all cases, I made some tests and the
NullPointerException still happens.
This time it happens in the TextBox.getRichTextRuns() when it tries to
return _txtrun.getRichTextRuns().

Hi,
This is the changes I make (works just the same):
RichTextRun[] rt;
if (_txtrun == null) rt = new RichTextRun[0];
else rt = _txtrun.getRichTextRuns();

PPT Pictures
Hi, I'm having trouble extracting images from PPT files. When I have the same image more than once, the API identifies only one image even if the size differs from one to another. I use the readPictures method in the HSLFSlideShow class which puts the image streams in the a pictstream vector. For instance, if there are 3 pictures, being 2 of them the same picture, the returned vector length is 2. What can I do to get the real images number?
