Apache POI will not set superscript inside a TextBox

Apache POI will not set superscript inside a TextBox - java

I need to use Apache POI(4.1.1) to write some text inside a textbox (or rectangle shape), and this text must have superscripts in it. I can get this to work for data inside a cell, but not when using a textbox. Here is a minimal example:
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Font;
import org.apache.poi.ss.usermodel.IndexedColors;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.*;
import java.io.FileOutputStream;
public class SuperScriptTest {
public static void main(String[] args) throws Exception {
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet ws = wb.createSheet("Sheet 1");
XSSFFont fontInfo = wb.createFont();
fontInfo.setFontName("Arial");
fontInfo.setFontHeightInPoints((short) 11);
XSSFFont fontInfoSuperscript = wb.createFont();
fontInfoSuperscript.setFontName("Arial");
fontInfoSuperscript.setFontHeightInPoints((short) 11);
fontInfoSuperscript.setTypeOffset(Font.SS_SUPER);
fontInfoSuperscript.setColor(IndexedColors.RED.getIndex());
Row row = ws.createRow(0);
Cell cell = row.createCell(0);
// Writing to a cell produces desired results:
XSSFRichTextString richString = new XSSFRichTextString("Level3");
richString.applyFont(fontInfo);
richString.applyFont(5, 6, fontInfoSuperscript);
cell.setCellValue(richString);
// Writing to a textbox does not:
XSSFDrawing drawing = ws.createDrawingPatriarch();
XSSFTextBox txtBox = drawing.createTextbox(new XSSFClientAnchor(0, 0, 0, 0, 0, 5, 2, 7));
XSSFRichTextString richString2 = new XSSFRichTextString("Level3");
richString2.applyFont(fontInfo);
richString2.applyFont(5, 6, fontInfoSuperscript);
txtBox.setText(richString2);
try (FileOutputStream fileOut = new FileOutputStream("Superscript.xlsx")) {
wb.write(fileOut);
}
}
}
The cell will give me the right font and size, and properly superscript the 3 and turn it red.
The textbox will give me the correct font and size, and will color the 3, but it will not superscript the 3.
Thank you for any help.

In Excel cells and text box shapes have different kinds of font settings. For Excel cells spreadsheet settings are used while for text box shapes drawing settings are used.
Because XSSFRichTextString mostly gets used for Excel cell values and shared strings, it internally uses spreadsheet settings. When it comes to XSSFRichTextStrings in context of shapes, the settings need to be converted. This is done in XSSFSimpleShape.setText(XSSFRichTextString str) using the method XSSFSimpleShape.applyAttributes(CTRPrElt pr, CTTextCharacterProperties rPr).
In spreadsheet settings CTRPrElt there is a CTVerticalAlignFontProperty used to set baseline, superscript or subscript. In drawing settings CTTextCharacterProperties there is a baseline attrtibute used which is 0 for baseline, +n% for superscript and -n% for subscript. There n% is the distance from the baseline.
Until now the XSSFSimpleShape.applyAttributes lacks converting CTVerticalAlignFontProperty to CTTextCharacterProperties.setBaseline. To get this, one could patching XSSFSimpleShape.applyAttributes like so:
private static void applyAttributes(CTRPrElt pr, CTTextCharacterProperties rPr) {
...
if (pr.sizeOfVertAlignArray() > 0) {
CTVerticalAlignFontProperty vertAlign = pr.getVertAlignArray(0);
if (vertAlign.getVal() == STVerticalAlignRun.BASELINE) {
rPr.setBaseline(0);
} else if (vertAlign.getVal() == STVerticalAlignRun.SUPERSCRIPT) {
rPr.setBaseline(30000); //30% distance from baseline == default superscript
} else if (vertAlign.getVal() == STVerticalAlignRun.SUBSCRIPT) {
rPr.setBaseline(-25000); //-25% distance from baseline == default subscript
}
}
}
For superscript 30% distance from baseline is choosen because that is the default when someone ticks text effect superscript in text box font settings. For subscript -25% distance from baseline is choosen because that is the default when someone ticks text effect subscript in text box font settings.

Setting axis title and adding values to the bar

I need to change the properties (like size of font) of the title axis (circled in red)
I'm using the apache-poi library and here's the part of the code which generates both titles
XDDFCategoryAxis bottomAxis = chart.createCategoryAxis(AxisPosition.BOTTOM);
bottomAxis.setTitle("Client Name");
XDDFValueAxis leftAxis = chart.createValueAxis(AxisPosition.LEFT);
leftAxis.setTitle("Value ("+clientDataObjectRequest.getDataFormatCodeValue()+")");
leftAxis.setCrosses(AxisCrosses.AUTO_ZERO);
leftAxis.setCrossBetween(AxisCrossBetween.BETWEEN);
I've already tried to use the method getOrAddTextProperties().setFontSize() but this change only the size of the labels (client names and numbers) and not the title itself.
In yellow, I would like to add the precisely number of the value. For example, the value of "client 3" is 53,78, so I need to put this value in the chart just after the end of the bar (marked as yellow).

The question about formatting the axes titles is answered already. See Resizing legend and axis title in a apache poi bar chart.
"To add the precisely number of the value" to the data bars means to have data labels set. This is not directly supported ny Apache POI until now. So using low level org.openxmlformats.schemas.drawingml.x2006.chart.* classes is necessary. See https://stackoverflow.com/search?tab=newest&q=user%3a3915431%20add%20data%20labels. Of course this is not very comfortable. So I have tried to create a method void setDataLabels(XDDFChartData.Series series, int pos, boolean... show) for this.
There int pos can be one of the following:
INT_BEST_FIT 1 - positions data label at best fit to be readable
INT_B 2 - positions data label at bottom
INT_CTR 3 - positions data label at center
INT_IN_BASE 4 - positions data label inside at base
INT_IN_END 5 - positions data label inside at the end
INT_L 6 - positions data label at left
INT_OUT_END 7 - positions data label outside at the end
INT_R 8 - positions data label at right
INT_T 9 - positions data label at top
Not all chart types support all positions.
The boolean... show is a list of boolean to tell what shall visible (true) or not visible (false) in the data labels. Sequence is as follows:
ShowVal, ShowLegendKey, ShowCatName, ShowSerName, ShowPercent, ShowBubbleSize, ShowLeaderLines

Resizing an EMF image in XSSFWorkbook

I am trying to resize an EMF image after inserting it into an XSSFWorkbook.
There is support resizing PNG, JPEG and DIB images.
private void addNormalFigure(XSSFSheet sheet, byte[] imgData){
XSSFWorkbook w = sheet.getWorkbook();
int picIdx = w.addPicture(imgData, Workbook.PICTURE_TYPE_EMF);
CreationHelper helper = w.getCreationHelper();
XSSFDrawing drawing = sheet.createDrawingPatriarch();
ClientAnchor anchor = helper.createClientAnchor();
// Column : A
anchor.setCol1(0);
// Row : 4
anchor.setRow1(4);
Picture pic = drawing.createPicture(anchor, picIdx);
double height = 2.0;
double width = 2.0;
// sets the anchor.col2 to 0 and anchor.row2 to 0
pic.getImageDimension().setSize(inchToPixel(width), inchToPixel(height));
// pic.resize(); -> this too sets the anchor.col2 to 0 and anchor.row2 to 0
}
private double inchToPixel(double in) {
return in * 96.0;
}
Is there any way we can workaround this problem?

Apache poi not provides to get image dimensions from Picture of type Workbook.PICTURE_TYPE_EMF. The used ImageUtils method getImageDimension only is able to get dimensions from JPEG, PNG and DIB pictures,
But apache poi provides org.apache.poi.hemf.usermodel.HemfPicture. So
import org.apache.poi.hemf.usermodel.HemfPicture;
...
HemfPicture hemfPicture = new HemfPicture(new ByteArrayInputStream(imgData));
System.out.println(hemfPicture.getSize());
...
will print the correct dimensions.
But then it lacks a possibility to set those dimensions to the anchor. There is a method scaleCell in ImageUtils but not public accessible. So only way would be to copy source code of that method into your code.
Following complete example does that. It uses methos scaleCell having same code as in ImageUtils. The method resizeHemfPicture resizes the Picture to the HemfPicture dimension.
This is tested and works using apache poi 5.0.0 and Java 12.

Java edit bar chart in ppt by using poi

I am a newbie to using POI at work.Now i'm going to use POI in java to read a bar chart in the PPT.I've added several series x to it in advance,which are the column headers of the excel to which the bar graph belongs.
But i can only read the first three columns by default with the POI.In addition,once I modify the column header of the bar chart,or want to add a fourth column(thar is,add a color)to a bar chart with only three columns, the bar chart cannot be edited when I open the PPT,indicating that the node of the bar chart is damaged.
So is there a master who can help talking how to use POI to prroperly add a color to the bar chart(add a series)?
Eg: when I debug to the "
long ptCatCnt = catDataSource.getStrRef().getStrCache().getPtCount().getVal();
It show nullpointerexecption, I don't know how structure in ppt the bar-chart is.So I want know how to update the bar-chart。
The code is :

Using current apache poi 5.0.0 updating a chart in PowerPoint is possible using the new XDDF classes. That avoids using the ooxml-schemas classes (CT... classes) directly. Using CT classes directly is error prone and needs very good knowlegde about the internally XML structure of Office Open XML.
What one needs to know is that chart data is stored in an embedded Excel workbook. So while updating the data the need is always updating the data in that workbook and updating the data in the chart.
The following example is a minimal reproducible example for how to do this.
The template BarChartSample.pptx contained a bar chart having only one series an one category. It defines the chart format. It looks like so:
The code is like this:

Issue with export CrossTab data into excel sheet using Java Apache POI 3.15 version

I am collecting data from my company portal and trying to export it into an excel sheet. I successfully completed for non-crosstab report data. But the issue is coming when the data has crosstab.
Data:
I have saved in data in ArrayList best on my best understanding.
1.
rowHeader:[Quarter, Subcategory]
2.
rowElement:[2016 Q1, 2016 Q2, 2016 Q3, 2016 Q4, Audio Equipment, Cameras, Computers, Electronics - Miscellaneous, TV's, Video Equipment]
3.
columnHeader:[Year, 2016]
4.
columnHeaders[Quarter, Subcategory, Year, 2016]
5.
metricsColumn:[Metrics, Profit, Profit Forecast, Profit Margin, Revenue, Revenue Forecast]
6.
listData:[[$9,579, $8,823, 19.42%, $49,320, $ 39,456], [$11,449, $9,619, 20.07%, $57,040, $ 53,047], [$4,901, $3,784, 20.02%, $24,480, $ 21,298], [$12,444, $9,525, 19.89%, $62,576, $ 53,815], [$8,820, $8,059, 20.19%, $43,675, $ 35,814], [$16,375, $12,986, 20.44%, $80,130, $ 70,514], [$8,526, $6,929, 15.78%, $54,020, $ 49,698], [$11,602, $9,578, 17.31%, $67,032, $ 63,680], [$4,675, $4,380, 16.83%, $27,780, $ 25,752], [$11,699, $9,421, 16.60%, $70,469, $ 54,966], [$9,386, $7,179, 17.52%, $53,563, $ 49,974], [$10,150, $9,213, 16.96%, $59,864, $ 48,490], [$8,508, $6,772, 17.16%, $49,571, $ 47,092], [$16,429, $13,529, 18.52%, $88,712, $ 83,389], [$6,009, $5,391, 18.05%, $33,295, $ 29,200], [$11,792, $9,791, 17.21%, $68,534, $ 64,285], [$9,243, $7,952, 17.15%, $53,886, $ 49,953], [$14,282, $11,679, 18.03%, $79,193, $ 74,441], [$10,999, $8,538, 15.60%, $70,511, $ 65,575], [$14,475, $11,433, 16.32%, $88,718, $ 78,515], [$5,765, $5,029, 16.77%, $34,373, $ 31,847], [$11,335, $9,567, 15.28%, $74,168, $ 62,672], [$11,990, $11,230, 16.83%, $71,255, $ 64,414], [$13,864, $11,328, 16.87%, $82,203, $ 70,695]]
Till so far, I successfully, completed exporting Headers section.
I am struggling, now exporting data into an excel sheet because of the crosstab we need to do column merge and row merge for every Quarters and Years.
If someone can help me, to write any sample code/ pseudo code for it, it would be a very very helpful for me. I ave stuck with this issue from the last 4 days. I am not getting how to do this part as I never used any exclsheet API. here I am using APACHE POI -3.15 version.
Code till so far, which export Header section:
//Create a Row
Row headerRow = sheet.createRow(0);
//int totalcolumns = rowHeader.size() + columnHeader.size();
int mergeHeader = 0;
if(metricsColumn != null) {
mergeHeader = 1;
}
//Create Cells //[Quarter, Subcategory, Year, 2016]
int j = rowHeader.size();
int row = 0;
for (int i = 0; i < columnHeaders.size(); i++) {
Cell cell = headerRow.createCell(i);
cell.setCellValue(columnHeaders.get(i));
if(j > 0) {
sheet.addMergedRegion(new CellRangeAddress(row, mergeHeader, i, i));
}
j--;
if (i == columnHeaders.size() - 1 && metricsColumn.size() > 0) {
sheet.addMergedRegion(new CellRangeAddress(0,0,i,i + metricsColumn.size() - 2));
}
cell.setCellStyle(headerCellStyle);
}
int k = 0;
int rowNum1 = 1;
int cellNum1 = 2;
Row row1 = sheet.createRow(rowNum1);
for (int i = rowHeader.size(); i < metricsColumn.size(); i++) {
while (k < metricsColumn.size()) {
Cell cell = row1.createCell(cellNum1++);
cell.setCellValue(metricsColumn.get(k));
cell.setCellStyle(headerCellStyle);
k++;
}
}

I would make the structures for headers and data a little bit different:
The headers for example:
String[][] headers = new String[][] {
new String[] {"Quarter", "Subcategory", "Year", "2016", null, null, null, null},
new String[] { null, null, "Metrics", "Profit", "Profit Forecast", "Profit Margin", "Revenue", "Revenue Forecast"}
};
Maybe List<List<String>> also would be possible.
The row headers:
String[] quarters = new String[]{"2016 Q1", "2016 Q2", "2016 Q3", "2016 Q4"};
String[] subcategories = new String[]{"Audio Equipment", "Cameras", "Computers", "Electronics - Miscellaneous", "TV's", "Video Equipment"};
Maybe List<String> also would be possible.
The values:
Double[][] values = new Double[][]{
new Double[]{9579d, 8823d, .1942, 49320d,39456d},
new Double[]{11449d, 9619d, .2007, 57040d, 53047d},
...
new Double[]{13864d, 11328d, .1687, 82203d, 70695d}
};
Maybe List<List<Double>> also would be possible.
Then I would also provide basic formatting instructions in structures. So it is later possible to set them using loops.
For example the basic table structure:
int[] columnWidths = new int[]{15*256, 15*256, 15*256, 13*256, 13*256, 13*256, 13*256, 13*256};
For example the headers horizontal alignment:
HorizontalAlignment[][] horizontalAlignments = new HorizontalAlignment[][]{
new HorizontalAlignment[]{HorizontalAlignment.LEFT, HorizontalAlignment.CENTER, HorizontalAlignment.LEFT, HorizontalAlignment.CENTER, null, null, null, null},
new HorizontalAlignment[]{null, null, HorizontalAlignment.RIGHT, HorizontalAlignment.CENTER, HorizontalAlignment.CENTER, HorizontalAlignment.CENTER, HorizontalAlignment.CENTER, HorizontalAlignment.CENTER}
};
And the merged regions for the headers:
int[][] headerMergedRegions = new int[][]{
new int[]{0, 0, 3, 7},
new int[]{0, 1, 0, 0},
new int[]{0, 1, 1, 1}
};
Then I would set the much used number formats in default column styles:
String[] columnCellStyles = new String[]{"default", "default", "default", "currency", "currency", "percent", "currency", "currency"};
...
// creating default cell style having default font
CellStyle defaultCellStyle = workbook.createCellStyle();
defaultCellStyle.setFont(defaultFont);
// we need currency style for numbers later
CellStyle currency = workbook.createCellStyle();
currency.cloneStyleFrom(defaultCellStyle);
currency.setDataFormat(format.getFormat("$#,##0"));
// we need percent style for numbers later
CellStyle percent = workbook.createCellStyle();
percent.cloneStyleFrom(defaultCellStyle);
percent.setDataFormat(format.getFormat("0.00%"));
...
// set default column styles
for (int c = 0; c < columnCellStyles.length; c++) {
String style = columnCellStyles[c];
if ("default".equals(style)) {
sheet.setDefaultColumnStyle(c, defaultCellStyle);
} else if ("currency".equals(style)) {
sheet.setDefaultColumnStyle(c, currency);
} else if ("percent".equals(style)) {
sheet.setDefaultColumnStyle(c, percent);
}
}
So when we set the values later, the cell styles can come from default column style. For this a method CellStyle getPreferredCellStyle(Cell cell) could be used.
For formatting I would rely on methods from CellUtil. So not all needed CellStyles needs to be created on workbook level but can be set to the cell into the loops.
For cell borders I would use PropertyTemplate. This makes setting borders much more easier.

CellStyle cellStyle = cell.getCellStyle();

How to move position of chart in excel by Java POI

I want to add row in excel by java POI and I try with both shiftRows() function and createRow() function
both function can add row in excel but below chart position is remain and not move
I also like to move (shift down) the position of chart
I use poi version 3.9
Can anyone give me the advice or idea to move the position of that chart image
As the fact, the data range of chart also not changed. I need not only to move the position of charts but also need to increase the data range of chart
thanks!!

The shifting of the drawing anchors which determine the chart positions is possible. The method void insertRowsShiftShapes(Sheet sheet, int startRow, int n) does this for all drawing anchors which are affected of row inserting process into the sheet.
The correcting of the chart data ranges which are affected of the row inserting into the sheet is complicated as said already. It is not well tested and not ready yet. But I will provide it as a working draft. I hope it is a useful start point for further programming.
For running the code the ooxml-schemas-1.3.jar is needed as mentioned in apache poi FAQ
A good resource for documentation of the ooxml-schema objects for me is grepcode
