Set the Font Color for the Text String on PDF
Spire.PDF for Java offers PdfSolidBrush class to set the brush color for the text. It supports to define the brush color based on a particular RGB color space or a HTML color code.
- Create a PdfDocument object.
- Add a new page in the PDF using PdfDocument.getPages().add() method.
- Create a PdfSolidBrush object based on a particular RGB color space or a HTML color code.
- Create an object of PdfTrueTypeFont to set the font name, size and style.
- Draw text on the page at the specified location using PdfPageBase.getCanvas().drawString() method.
- Save the document to another PDF using PdfDocument.saveToFile() method.
- Java
import com.spire.pdf.PdfDocument;
import com.spire.pdf.PdfPageBase;
import com.spire.pdf.graphics.PdfRGBColor;
import com.spire.pdf.graphics.PdfSolidBrush;
import com.spire.pdf.graphics.PdfTrueTypeFont;
import java.awt.*;
public class pdfBrush {
public static void main(String[] args) throws Exception {
//Create a PdfDocument object
PdfDocument doc = new PdfDocument();
//Add a page
PdfPageBase page = doc.getPages().add();
//Set the location
float y = 30;
//Create solid brush object and define the color
PdfRGBColor rgb1 = new PdfRGBColor(Color.green);
PdfSolidBrush brush1 = new PdfSolidBrush(rgb1);
//RGB Color
PdfRGBColor rgb2 = new PdfRGBColor(0,197,205);
PdfSolidBrush brush2 = new PdfSolidBrush(rgb2);
//HTML code color
Color color = Color.decode("#A52A2A");
PdfSolidBrush brush3 = new PdfSolidBrush(new PdfRGBColor(color));
//Create true type font object
Font font = new Font("Arial", java.awt.Font.BOLD, 14);
PdfTrueTypeFont trueTypeFont = new PdfTrueTypeFont(font);
//Draw text
page.getCanvas().drawString("Set the text color with brush", trueTypeFont, brush1, 0, (y = y + 30f));
page.getCanvas().drawString("Set the text color with RGB", trueTypeFont, brush2, 0, (y = y + 50f));
page.getCanvas().drawString("Set the text color with HTML code color", trueTypeFont, brush3, 0, (y = y + 60f));
//Save to file
doc.saveToFile("output/CreatePdf.pdf");
}

Set Background Color and Pattern for Excel Cells
The detailed steps are as follows.
- Create a Workbook object.
- Load a sample Excel document using Workbook.loadFromFile() method.
- Get a specified worksheet using Workbook.getWorksheets().get() method.
- Get a specified cell range using Worksheet.getRange().get() method.
- Set background color for the specified cell range using CellRange.getStyle().setColor() method.
- Set fill pattern style for the specified cell range using CellRange.getStyle().setFillPattern() method.
- Save the result to another file using Workbook.saveToFile() method.
- Java
import com.spire.xls.*;
import java.awt.*;
public class CellBackground {
public static void main(String[] args) {
//Create a Workbook object
Workbook workbook = new Workbook();
//Load a sample Excel document
workbook.loadFromFile("C:\\Users\\Administrator\\Desktop\\data.xlsx");
//Get the first worksheet
Worksheet worksheet= workbook.getWorksheets().get(0);
//Set background color for range "A1:E1" and "A2:A10"
worksheet.getRange().get("A1:E1").getStyle().setColor(Color.green);
worksheet.getRange().get("A2:A10").getStyle().setColor(Color.yellow);
//Set background color for cell E8
worksheet.getRange().get("E8").getStyle().setColor(Color.red);
//Set fill pattern style for range "C4:D5"
worksheet.getRange().get("C4:D5").getStyle().setFillPattern(ExcelPatternType.Percent25Gray);
//Save the document
workbook.saveToFile("CellBackground.xlsx", ExcelVersion.Version2013);
