Hi guys,
I am using 3.5" TFT display with Arduino uno, Mcufriend_kbv library to display the 24 bit bitmap image on the tft display.
I am trying to display a image but image is getting detoriated as attached in the figure below.
Figure 1 is the original image.
Figure2 contains the image displayed on the tft display.
Sketch I am using is also attached below.
Please help me in solving the problems guys.

You can attach many types of file e.g. C, CPP, ZIP, PNG, ...

Simply put every file into your ZIP.

I would like to see the original BMP file(s) that you are trying to render.
And photos of what you actually get on the screen.

David.

It is not taking my attachments.
Well that is anti-social. I had all ready replied to you several times and you post again and delete the other postings.

Why did you remove the sketch.zip attachment?
Please post the sketch you are using.

It was not taking the image and code so I had to post it several time.
Sorry for the trouble guys.

How are you loading the image to the display?

You bundle everything into a single zip archive and attach it.
plain and simple.

You did not need to start posting all over again.
You reply to the original posting just like we do.

The original image in the image.zip file; it that the image before you copied it to the SD card or is it the image from the SD card?

The SD card holder is on the TFT display?

Can you please provide the make and model of the TFT display.

I provided a "landscape" picture.   i.e. 320x200 24bits per pixel.

I can't remember whether the example rotates the screen to display landscape.   Or just stops in portrait mode.

Your Figure1.bmp seems to be 200x200 but skewed.

How did you produce a skewed picture?
Photos are normally PNG, JPG, ... and not BMP
You can edit the BMP on the PC.

You can read the screen and recreate another BMP with your Arduino.   But it is a lot easier with PC tools.

There is a arduino tft shield we are connecting it directly.

Can you provide a link in the proper tags to the TFT display?

Waiting on the circuit diagram.
Waiting on the sketch in a zip archive.
