Render a texture using alternate blending mode, with red and blue channels flipped in the shader.

Parameters:

  • texture – OpenGL texture ID

  • texture_area – the area in the window to render the texture in

  • opa – opacity to blend the texture with existing contents

  • disp_w – width of the window/framebuffer being rendered to

  • disp_h – height of the window/framebuffer being rendered to

  • h_flip – horizontal flip

  • v_flip – vertical flip

void lv_opengles_regular_viewport(int32_t x, int32_t y, int32_t w, int32_t h)

Set the OpenGL viewport, with vertical co-ordinate conversion

Parameters:

  • x – x position of the viewport

  • y – y position of the viewport

  • w – width of the viewport

  • h – height of the viewport
