I’m using drivework and I want to make the font size larger, but I can’t find the interface for font size. Can you help me?

Dear @deng.shigang,
May I know which font? Is it the output text in the GL window?

yes.

In the sample_stereo_disparity example, I wanted to change the code so that the font size for the depth values displayed when the mouse clicks is larger. But I don’t know where to modify.

Dear @deng.shigang,
We have dwRenderEngine_setFont to set the font of render engine. If you asking to change the size of display text when mouse is clicked, you can do like below in the code.

// Render depth on mouse click
                if (m_depthFlag[side])
                {
                    uint32_t imageRow = static_cast<uint32_t>(m_depth[side].y * m_disparityCPU[side]->prop.height);
                    uint32_t imageCol = static_cast<uint32_t>(m_depth[side].x * m_disparityCPU[side]->prop.width);
                    uint32_t disp     = m_disparityCPU[side]->data[0][imageRow * m_disparityCPU[side]->prop.width + imageCol];
                    char depth[10];
                    sprintf(depth, "%.1f", m_focalLength[side] * m_baseline / (disp * m_depthGain));


#Newly added snippet in code to increase font size                   
                    dwRenderEngineFont newFont = DW_RENDER_ENGINE_FONT_VERDANA_64;
                    dwRenderEngine_setFont(newFont, m_renderEngine);
                    std::cout << "Depth font is " << font << std::endl;
                    


CHECK_DW_ERROR(dwRenderEngine_setColor(DW_RENDER_ENGINE_COLOR_WHITE, m_renderEngine));
                    CHECK_DW_ERROR(dwRenderEngine_renderText2D(depth, dwVector2f{m_depth[side].x, m_depth[side].y}, m_renderEngine));
                }
            }

Thank you very much. Problem solved
