slint::platform::SoftwareRenderer::TargetPixelBuffer Struct

template <typename PixelType>
struct TargetPixelBuffer;

C++

#include <slint-platform.h>

C++

Abstract base class for a target pixel buffer where certain drawing operations can be delegated. Use this to implement support for hardware accelerators such as DMA2D, PPA, or PXP on Microcontrollers.

Note: This class is still experimental - its API is subject to changes and not stabilized yet. To use the class, you must enable the SLINT_FEATURE_EXPERIMENTAL=ON CMake option.

Public Functions

~TargetPixelBuffer (virtual)

slint::platform::SoftwareRenderer::TargetPixelBuffer< PixelType >::~TargetPixelBuffer()

line_slice (pure virtual)

std::span< PixelType > slint::platform::SoftwareRenderer::TargetPixelBuffer< PixelType >::line_slice(std::size_t line_number)=0

Returns a span of pixels for the specified line number.

num_lines (pure virtual)

std::size_t slint::platform::SoftwareRenderer::TargetPixelBuffer< PixelType >::num_lines()=0

Returns the number of lines in the buffer. This is the height of the buffer in pixels.

draw_texture (pure virtual)

bool slint::platform::SoftwareRenderer::TargetPixelBuffer< PixelType >::draw_texture(const DrawTextureArgs &texture, const PhysicalRegion &clip)=0

Draw a portion of provided texture to the specified pixel coordinates. Each pixel of the texture is to be blended with the given colorize color as well as the alpha value.

fill_background (pure virtual)

bool slint::platform::SoftwareRenderer::TargetPixelBuffer< PixelType >::fill_background(const Brush &brush, const PhysicalRegion &clip)=0

Fill the background of the buffer with the given brush.

draw_rectangle (pure virtual)

bool slint::platform::SoftwareRenderer::TargetPixelBuffer< PixelType >::draw_rectangle(const DrawRectangleArgs &args, const PhysicalRegion &clip)=0

Draw a rectangle specified by the DrawRectangleArgs. That rectangle must be clipped to the given region.
