PNMTextMaker

from panda3d.core import PNMTextMaker

class PNMTextMaker

Bases:

Bases: FreetypeFont

This object uses the Freetype library to generate text directly into an image. It is different from the TextNode/DynamicTextFont interface, which use the Freetype library to generate text in the scene graph, to be rendered onscreen via the Panda render traversal.

Inheritance diagram

enum Alignment

enumerator A_left = 0

enumerator A_right = 1

enumerator A_center = 2

__init__(font_filename: Filename, face_index: int): The constructor expects the name of some font file that FreeType can read, along with face_index, indicating which font within the file to load (usually 0).

__init__(copy: FreetypeFont)

__init__(copy: PNMTextMaker)

__init__(font_data: str, data_length: int, face_index: int): This constructor works as above, but it takes the font data from an in- memory buffer instead of from a named file.

calcWidth(text: str) → int: Returns the width in pixels of the indicated line of text.

calcWidth(text: str) → int: Returns the width in pixels of the indicated line of text.

generateInto(text: str, dest_image: PNMImage, x: int, y: int) → int: Generates a single line of text into the indicated image at the indicated position; the return value is the total width in pixels.

generateInto(text: str, dest_image: PNMImage, x: int, y: int) → int: Generates a single line of text into the indicated image at the indicated position; the return value is the total width in pixels.

getAlign() → Alignment

getDistanceFieldRadius() → int: Returns the radius previously set with setDistanceFieldRadius(), or 0 otherwise.

getFg() → LColor: Returns the foreground color of text that will be generated by future calls to generateInto().

getGlyph(character: int) → PNMTextGlyph: Returns the glyph for the indicated index, or NULL if it is not defined in the font.

getInterior() → LColor: Returns the color that will be used to render the interior portions of hollow fonts.

getInteriorFlag() → bool

isValid() → bool: Returns true if the PNMTextMaker is valid and ready to generate text, false otherwise.

setAlign(align_type: Alignment)

setDistanceFieldRadius(radius: int): If this is set to something other than 0, Panda will generate a signed distance field with the given radius.

setFg(fg: LColor): Sets the foreground color of text that will be generated by future calls to generateInto(). This is the color that all of the “on” pixels in the font will show as.

setInterior(interior: LColor): Sets the color that will be used to render the interior portions of hollow fonts in future calls to generateInto(). This is respected only if interior_flag is true.

setInteriorFlag(interior_flag: bool)

Sets the flag that indicates whether the interior of hollow fonts is identified as a preprocess as each glyph is loaded. If this flag is true, you may specify an interior color along with a fg and bg color when you place text; if the flag is false, the interior color is ignored.

It is generally best to set_native_antialias(0) when using this feature. Also, this works best when the pixel size is not very small.
