поменял AddImage на AddImageRounded и ничего

рендери картинку не от начала экрана и до конца, а от начала окна и до конца окна, ток тебе надо будет еще 2 аргумента поменять какую область текстуры рендерить

рендери картинку не от начала экрана и до конца, а от начала окна и до конца окна, ток тебе надо будет еще 2 аргумента поменять какую область текстуры рендерить

Попробовал сделать так

void _draws(ImDrawList* drawList, const ImVec2& p_min, const ImVec2& p_max, float alpha) noexcept
    {
        createTextures();
        createShaders();

        if (!blurTexture1 || !blurTexture2)
            return;

        drawList->AddCallback(&begin, nullptr);
        for (int i = 0; i < 8; ++i) {
            drawList->AddCallback(&firstPass, nullptr);
            drawList->AddImageRounded(reinterpret_cast<ImTextureID>(blurTexture1), p_min, p_max, ImVec2(0,0), ImVec2(1, 1), IM_COL32_WHITE, 10, ImDrawFlags_RoundCornersAll);

        }
        drawList->AddCallback(&end, nullptr);
        drawList->AddCallback(ImDrawCallback_ResetRenderState, nullptr);

#ifdef _WIN32
        drawList->AddImageRounded(reinterpret_cast<ImTextureID>(blurTexture1), p_min, p_max, ImVec2(backbufferWidth * 1, backbufferHeight * 1), ImVec2(backbufferWidth * 1, backbufferHeight * 1), IM_COL32(150, 150, 150, 255 * alpha), 10, ImDrawFlags_RoundCornersAll);
#else
        drawList->AddImage(reinterpret_cast<ImTextureID>(blurTexture1), p_min, p_max, ImVec2(backbufferWidth * 1, backbufferHeight * 1), ImVec2(backbufferWidth * 1, backbufferHeight * 1), IM_COL32(255, 255, 255, 255 * alpha));

тоже самое

тоже самое

p_min и p_max чему равно?
p_min = ImGui::GetWindowPos( );
p_max = ImGui::GetWindowSize( );
так?

p_max = ImGui::GetWindowPos( ) + ImGui::GetWindowSize( );*

p_max = ImGui::GetWindowPos( ) + ImGui::GetWindowSize( );*

ну я хотел ему сказать что к размеру нужно позицию добавлять
но ладно
