I am using apache poi 3.17 for generating *.xlsx files.
For a reason I don't know, the setWrapText(true) (merged cells) function of the class CellStyleDesc does not trigger the resizing of the row's height as it should be.
Could someone help me?

I need to filter out excel colored text lines, I found that tFilterRow is not able to do it, is someone were able to resolve that using Java code or some other way?

I used docx4j for excel implementation.
By using code I drew text frame , then a table and then again a text frame.
I used xdr:absoluteAnchor instead of xdr:twoCellAnchor.
But i noticed that my last (3rd) text frame is moved slightly down.
Is there any way to avoid such shape auto re-placement(auto movement) ?
You should create a text frame in Excel which behaves as you wish, then create corresponding Java code, which you can do by feeding your sample xlsx into http://webapp.docx4java.org/OnlineDemo/PartsList.html
For more help, you'll need to add the XML to your question.
Recently, I've met a problem on how to set the text into the vertical top using XSSF, I need to put the text in the top of one cell, but when I use
cellStyle.setVerticalAlignment(CellStyle.VERTICAL_TOP);
it always show the text in the middle center of the cell, i'm so confused and don't know which method i need to change, very appreciate someone could give me some hints, thanks so much in advance!
How to make the text direction in Apache poi as Vertical.
I tried Vertical alignment. I am not able to get the desired results.
I don't want to rotate the text.
Something like :
T
E
X
T
You have to create a cellStyle, where You have a method setRotation(short rotation). Subsequently apply the cellstyle to Your cell.
docs, for setRotation

I wanted o know whether it's possible to compress a given image to a predefined size in apache POI.
Say I have an input image of 500X500, and I want to convert to a thumbnail size (40X40), can I do it in apache POI?
if not, does java library provide any image processing capabilities?
Right now, I was able to embed images using apache POI, but I have no control over forcing the image to be with in a certain cell size.
Thanks.
The Picture interface in POI has resize methods as in the Javadocs
void resize(double scale)
Parameters:
scale - the amount by which image dimensions are multiplied relative
to the original size. resize(1.0) sets the original size, resize(0.5)
resize to 50% of the original, resize(2.0) resizes to 200% of the
original.
Use either the HSSFPicture or XSSFPicture implementations
Since Apache POI is designed to deal with Microsoft Documents, I wouldn't say it isn't possible.
A quick look through the Java Doc and nothing jumps out at me.
Image resizing is a fun exercise with lots of trade offs and options.
