Image problems using TFT_eFEX library #37

Closed stephensaid closed 1 year ago

stephensaid commented 3 years ago

Thanks, Bodmer.

I've implemented TFT_eFEX.

I now have a problem with the images. The following image is not right. IMG_20210302_205633

It should look like: image

I have other images with the same behaviour.

I've tried changing tft.setSwapBytes(true); to tft.setSwapBytes(false); but it has no effect.

Please help.

I don't have enough information to help. You need to provide a complete sketch that illustrates the problem and describe your hardware setup.

hi the same for me ... the sketch is the demo : Rotated_Sprite_3 and image is the original eye. thanks for help!

Bodmer commented 3 years ago

@fotosettore the OP question is for TFT_eFEX, Rotated_Sprite_3 in an example of TFT_eSPI so please raise a new issue.

Dear Bodmer,

Hope you are doing well.

It has been a while but had other things to work on and temporarily abandoned this project. I appreciate that you have left this issue open since then.

I updated TFT_eSPI to 2.3.70 and am running TFT_eFEX 0.0.8.

Please view the source here.

This is very much under construction and I am learning as I go.

As soon as you run the code, the first thing you will see is the splash screen which I have posited in my first post. There are other icons that have the same issue. You might want to replace config_sample.txt with config.txt and edit SSID and Password. Be sure to upload config.txt and most importantly the images and fonts to SPIFFS.

Many thanks in advance. Stephen

Hi,

Changing fex.drawJpeg to fex.drawJpgFile fixed this issue.
