Overview

The Texture class contains methods for obtaining information about textures that are part of your materials in your model (within the In-Model section of the Materials Browser). Remember, textures are repeatable images that “tile” when painted on a surface.

Instance Method Details

↑ #average_color ⇒ Sketchup::Color?

The average_color method retrieves a color object with the average color found in the texture.

Examples:

model = Sketchup.active_model
materials=model.materials
# Adds a material as an in model material
m = materials.add "Test Color"
begin
  # Returns nil if not successful, path if successful
  m.texture = "c:\\Materials\\Carpet.jpg"
rescue
  puts $!.message
end
texture = m.texture
# Returns a color object
color = texture.average_color

Returns:

  • (Sketchup::Color, nil) —

    a color object (if successful), nil if unsuccessful.

  • SketchUp 6.0

↑ #filename ⇒ String

Note:

Since SketchUp 2021.0 this method will append a file extension matching the image format if the file extension is missing from stored filepath.

The #filename method retrieves the full path, if available, for a texture object.

Textures for materials shipping with SketchUp might only have a filename, since the path would be invalid on the end user's machine. Textures dynamically created from ImageRep objects may have an empty path unless saved with ImageRep#save_file or until the texture is saved with #write.

If you need only the filename of the texture use filename = File.basename(texture.filename).

Examples:

model = Sketchup.active_model
materials = model.materials
material = materials.add("Test Color")
material.texture = "c:\\Materials\\Carpet.jpg"
texture = material.texture
filename = texture.filename

Returns:

  • (String) —

    a string representation of the path and filename used for the texture.

Version:

  • SketchUp 6.0

↑ #height ⇒ Integer

The height method is used to get the height of a repeatable texture image, in inches.

Examples:

height = texture.height

Returns:

  • (Integer) —

    the height, in inches, of the texture pattern

Version:

  • SketchUp 6.0

↑ #image_height ⇒ Integer

The image_height method retrieves the height of the repeatable texture image, in pixels.

Examples:

imageheight = texture.image_height

Returns:

  • (Integer) —

    the height, in pixels, of the texture pattern

Version:

  • SketchUp 6.0

↑ #image_rep(colorized = false) ⇒ Sketchup::ImageRep

The #image_rep method returns a copy of a ImageRep object representing the texture pixel data.

Examples:

texture = Sketchup.active_model.materials[0].texture
image_rep = texture.image_rep

Parameters:

  • colorized (Boolean) (defaults to: false) —

    Set to true to obtain the colorized version.

Returns:

Version:

  • SketchUp 2018

↑ #image_width ⇒ Integer

The image_width method retrieves the width of the repeatable texture image, in pixels.

Examples:

imagewidth = texture.image_width

Returns:

  • (Integer) —

    the width, in pixels, of the texture pattern

Version:

  • SketchUp 6.0

↑ #size=(size) ⇒ Integer, Array(Integer, Integer)

The size= method allows you to set the size of the repeatable texture image, in inches,

Examples:

size = texture.size = 60
imagewidth = texture.width

if (imagewidth)
  puts imagewidth
else
  puts "Failure"
end

# Using two values which will not preserve ratio
width_height = texture.size = [10,100]

Parameters:

  • size (Integer, Array(Integer, Integer)) —

    The size, in inches, of the texture. This number will apply to height and width to keep aspect ratio. You can also pass as a parameter an array of two numeric values which will set width and height regardless of maintaining the height/width ratio.

Returns:

  • (Integer, Array(Integer, Integer)) —

    the size, in inches, of the texture. This number will apply to height and width to keep aspect ratio. If you have passed in an array of two numbers for width and height, the same array will be returned if successful.

Version:

  • SketchUp 6.0

↑ #valid? ⇒ Boolean

The valid? method ensures that a texture is valid.

Examples:

status = texture.valid?

Returns:

  • (Boolean)

Version:

  • SketchUp 6.0

↑ #width ⇒ Integer

The width method is used to get the width of a repeatable texture image, in inches.

Examples:

width = texture.width

Returns:

  • (Integer) —

    the width, in inches, of the texture pattern

Version:

  • SketchUp 6.0

↑ #write(path, colorize = false) ⇒ Boolean

Writes the texture to file with option to preserve the color adjustments made by the material.

Examples:

material = Sketchup.active_model.materials[0]
basename = File.basename(material.texture.filename)
path = File.join(Sketchup.temp_dir, basename)
material.texture.write(path)

Parameters:

  • path (String) —

    The file path to write the texture to.

  • colorize (Boolean) (defaults to: false) —

    Boolean - Allows for the texture to be exported with the color adjustments.

Returns:

  • (Boolean) —

    true if the method succeeded
