33 * has no shader, then the paint's color is used. If the paint has a
34 * shader, then the shader's color(s) are use instead, but they are
35 * modulated by the paint's alpha. This makes it easy to create a shader
37 * w/o having to modify the original shader... only the paint's alpha needs
48 * FIXME: This can be incorrect for a Shader with its own local matrix

96 * Returns true if the shader is guaranteed to produce only opaque
97 * colors, subject to the SkPaint using the shader to apply an opaque

140 * Called sometimes before drawing with this shader. Return the type of
141 * alpha your shader will return. The default implementation returns 0.
204 // Reference to shader, so we don't have to dupe information.
240 * Returns true if this shader is just a bitmap, and if not null, returns the bitmap,
254 * Iff this shader is backed by a single SkImage, return its ptr (the caller must ref this
255 * if they want to keep it longer than the lifetime of the shader). If not, return nullptr.
266 * If the shader subclass can be represented as a gradient, asAGradient
320 * If the shader subclass is composed of two shaders, return true, and if rec is not NULL,
321 * fill it out with info about the shader.
356 * Returns a GrFragmentProcessor that implements the shader for the GPU backend. NULL is
372 * If the shader can represent its "average" luminance in a single color, return true and

386 * The specified matrix will be applied before any matrix associated with this shader.

400 * Call this to create a new "empty" shader, that will not draw anything.
405 * Call this to create a new shader that just draws the specified color. This should always
406 * draw the same as a paint with this color (and no shader).
411 * Create a shader that draws the specified color (in the specified colorspace).
