    • semi transparency of GUI_MEMDEV_PunchOutDevice

      We try Windows simulation " SimulationTrial.vcxproj " of V6.20 for the sample code GUI_MEMDEV_PunchOutDevice on page 2465, it is OK that background color is black color for mask device, we change the background color into the other color to obtain the semi transparency of mask device, the result fails. Do we mistake the method of GUI_MEMDEV_PunchOutDevice ? Thanks

    • Hi,

      After running the example in the manual, I would expect the circle to be anti-aliased, but it was not. You can see my output in the attachments.

      We will look into this issue.

      Best regards,
      Florian

    • Hi,

      The issue has been fixed and the fix will be released with the next general release (emWin V6.22). This issue only occurs with GUI_USE_ARGB == 1 and because GUI_DM_TRANS is used in the sample.

      Best regards,
      Florian
