Guest Gleb Posted June 5, 2018 Report Posted June 5, 2018 Hi, can you tell me how to draw a picture with translucency using ugfx. Sorry for my English)
Joel Bodenmann Posted June 5, 2018 Report Posted June 5, 2018 Hi, You just need to use an image format which supports transparency. The existing GIF and PNG image decoders will handle transparency out of the box.
Guest Gleb Posted June 5, 2018 Report Posted June 5, 2018 Thanks for the answer! Transparency works only with 100% absence or availability. If the color has a transparency of 50%, then it will by default be absent in these places.
Joel Bodenmann Posted June 5, 2018 Report Posted June 5, 2018 It seems that you're confusing transparency and alpha-channel. If you're using GIF then that's expected as GIF doesn't support alpha buy only transparency. If you're using PNG you should refer to the documentation: https://wiki.ugfx.io/index.php/Images#Alpha_.26_Transparency
Guest Gleb Posted June 6, 2018 Report Posted June 6, 2018 Thank you, will there be once an alpha channel with a transparent background picture, at least with the transfer of the background color to the method?
Joel Bodenmann Posted June 9, 2018 Report Posted June 9, 2018 Sorry, I do not understand your question.
