Method Summary

static com.lowagie.text.pdf.PdfPTable	buildTable(java.util.List<Block> items, PJsonObject params, RenderingContext context, int nbColumns, TableConfig tableConfig) Creates a PDF table with the given items.
static com.lowagie.text.pdf.PdfPCell	createCell(PJsonObject params, RenderingContext context, Block block, int row, int col, int nbRows, int nbCols, TableConfig tableConfig) Create a PDF table cell with support for styling using the CellConfig stuff.
static com.lowagie.text.Image	createImage(RenderingContext context, double maxWidth, double maxHeight, java.net.URI url, float rotation)
static com.lowagie.text.Chunk	createImageChunk(RenderingContext context, double maxWidth, double maxHeight, java.net.URI url, float rotation)
static com.lowagie.text.pdf.PdfPTable	createPlaceholderTable(double width, double height, double spacingAfter, ChunkDrawer drawer, HorizontalAlign align, PDFCustomBlocks customBlocks) When we have to do some custom drawing in a block that is layed out by iText, we first give an empty table with the good dimensions to iText, then iText will call a callback with the actual position.
static java.lang.String	evalString(RenderingContext context, PJsonObject params, java.lang.String val) Evaluates stuff like "toto ${titi}"
static com.lowagie.text.Image	getImage(RenderingContext context, java.net.URI uri, float w, float h) Gets an iText image with a cache that uses PdfTemplates to re-use the same bitmap content multiple times in order to reduce the file size.
protected static com.lowagie.text.Image	getImageDirect(RenderingContext context, java.net.URI uri) Gets an iText image.
static com.lowagie.text.Phrase	renderString(RenderingContext context, PJsonObject params, java.lang.String val, com.lowagie.text.Font font)

Throws:

java.io.IOException

com.lowagie.text.DocumentException

getImageDirect

protected static com.lowagie.text.Image getImageDirect(RenderingContext context,
                                                       java.net.URI uri)

com.lowagie.text.DocumentException

createPlaceholderTable

public static com.lowagie.text.pdf.PdfPTable createPlaceholderTable(double width,
                                                                    double height,

When we have to do some custom drawing in a block that is layed out by iText, we first give an empty table with the good dimensions to iText, then iText will call a callback with the actual position. When that happens, we use the given drawer to do the actual drawing.
