| Method Summary | |
| protected static void | collectFonts(Set fonts, CSContent content, PDResources resources, boolean considerTR)
| | protected static PDFont | createLazyFont(PDDocument document, COSName name)
A builtin font created "on the fly"
A font was requested in a content stream that can't be looked up in the
associated resources. | | public static PDFont | getFont(PDDocument document, PDResources resources, COSName name)
The font name, looked up in resources. | | public static PDFont | getFont(PDResources resources, COSName name)
The font name, looked up in resources. | | public static List | getFonts(PDDocument doc)
Determine the fonts contained as objects within the document. | | public static float | getGlyphHeight(PDFont font)
The font height in user space coordinates. | | public static float | getGlyphHeightScaled(PDFont font, float size)
The scaled font height in user space coordinates. | | public static int | getGlyphWidth(PDFont font, byte[] codepoints, int offset, int length)
The sum of the length of all glyphs referenced by length
bytes from codepoints starting at offset. | | public static float | getGlyphWidthScaled(PDFont font, float size, byte[] codepoints, int offset, int length)
The scaled sum of the length of all glyphs referenced by
length bytes from codepoints starting at
offset. | | public static float | getGlyphWidthScaled(PDFont font, float size, int codepoint)
The scaled width of the glyphs referenced by codepoint . | | public static List | getUsedFonts(PDDocument doc, boolean considerTR)
Tries to determine which fonts are really used within the document
The following criteria are used to determine usage of a font. |
| createLazyFont | | protected static PDFont createLazyFont(PDDocument document, COSName name)(Code) | | A builtin font created "on the fly"
A font was requested in a content stream that can't be looked up in the
associated resources. Some PDF engines just omit the font object when
dealing with builtins - try to interpret as such.
Parameters:
document - The document requesting the font.
Parameters:
name - The fonts name A builtin font created "on the fly" |
| getFont | | public static PDFont getFont(PDDocument document, PDResources resources, COSName name)(Code) | | The font name, looked up in resources.
When no matching resource is found, a builtin font is created on the fly.
Parameters:
document -
Parameters:
resources -
Parameters:
name - The font name, looked up inresources. |
| getFont | | public static PDFont getFont(PDResources resources, COSName name)(Code) | | The font name, looked up in resources.
Parameters:
resources -
Parameters:
name - The font name, looked up inresources. |
| getFonts | | public static List getFonts(PDDocument doc)(Code) | | Determine the fonts contained as objects within the document.
Parameters:
doc - The PDDocument to parse Collection of all PDFont objects in the document. |
| getGlyphHeight | | public static float getGlyphHeight(PDFont font)(Code) | | The font height in user space coordinates.
Parameters:
font - The font to be used.
Parameters:
size - The font size The scaled font height in user space coordinates. |
| getGlyphHeightScaled | | public static float getGlyphHeightScaled(PDFont font, float size)(Code) | | The scaled font height in user space coordinates.
Parameters:
font - The font to be used.
Parameters:
size - The font size The scaled font height in user space coordinates. |
| getGlyphWidth | | public static int getGlyphWidth(PDFont font, byte[] codepoints, int offset, int length)(Code) | | The sum of the length of all glyphs referenced by length
bytes from codepoints starting at offset.
Parameters:
font -
Parameters:
codepoints -
Parameters:
offset -
Parameters:
length - The sum of the length of all glyphs referenced bylength bytes from codepointsstarting at offset. |
| getGlyphWidthScaled | | public static float getGlyphWidthScaled(PDFont font, float size, byte[] codepoints, int offset, int length)(Code) | | The scaled sum of the length of all glyphs referenced by
length bytes from codepoints starting at
offset.

codepoints -
Parameters:
offset -
Parameters:
length - The scaled sum of the length of all glyphs referenced bylength bytes from codepointsstarting at offset. |
| getGlyphWidthScaled | | public static float getGlyphWidthScaled(PDFont font, float size, int codepoint)(Code) | | The scaled width of the glyphs referenced by codepoint .
Parameters:
font -
Parameters:
size -
Parameters:
codepoint - The scaled sum of the length of all glyphs referenced bylength bytes from codepointsstarting at offset. |
| getUsedFonts | | public static List getUsedFonts(PDDocument doc, boolean considerTR)(Code) | | Tries to determine which fonts are really used within the document
The following criteria are used to determine usage of a font.
Any glyph of the font is referenced in
- the Contents stream of a page object
- the stream of a Form XObject
- the appearance stream of an annotation, including form fields
- the content stream of a Type 3 font glyph
- the stream of a tiling pattern
Parameters:
doc - The PDDocument to parse
Parameters:
considerTR - If true, considers font references with Text rendering mode 3as unused Set of all used fonts |
