How to scale with display.drawJpg?



  • I know this is not completely the right topic.
    Anyway,
    I want to scale my jpg, lets say to half its size. I am trying to understand the syntax, but no luck.
    This is what I use :
    display.drawJpg(JPG_buffer_processed, Append_this_Struct.JPG_size, 0, 0, Append_this_Struct.JPG_width,Append_this_Struct.JPG_height, 1.0f, 0.5f)
    assuming the last two floats are a scale factor.
    But my jpg stays the same size.
    Anyone any idea how to scale my jpg ?
    thanks



  • You are better off scaling the images in GIMP and save the smaller images to the core





  • Thanks,
    Indeed,
    This works :
    display.drawJpg(JPG_buffer_processed, Append_this_Struct.JPG_size, 0, 0, Append_this_Struct.JPG_width,Append_this_Struct.JPG_height,0,0,JPEG_DIV_2);
