swap not declared

I'm using arduino IDE 1.6.6 with arduino uno. All examples sort the same error

C:\Users\Eraldo\Documents\Arduino\libraries\SWTFT\SWTFT.cpp: In member function 'void SWTFT::drawLine3Byte(int16_t, int16_t, int16_t, int16_t, uint8_t, uint8_t, uint8_t)':

C:\Users\Eraldo\Documents\Arduino\libraries\SWTFT\SWTFT.cpp:629:16: error: 'swap' was not declared in this scope

 swap(x0, y0);

            ^

C:\Users\Eraldo\Documents\Arduino\libraries\SWTFT\SWTFT.cpp:634:16: error: 'swap' was not declared in this scope

 swap(x0, x1);

            ^

exit status 1
Errore durante la compilazione

Anyone has an idea? Thanks

Display is white. It doesn't show any text after uploading the code. Any fixes?

BMP files

I tried the example tftbmp, but with guidance set to 1 or 3 is not working.

Wont work on Leonardo?

Hi, any idea what is needed for this to work on a Leonardo please?

drawPixel() doesn't work after setRotation()

drawPixel() alters its behaviour based on the rotation data member. But if you've called SWTFT::setRotation() the hardware is already dealing with it, so it's applied "twice". The rendering gets messed up; pixels pile up on the edges.

tftpaint doesn't compile

The three of the four examples work (great, many thanks!) , but tftpaint does not compile :-(
Below is the compiler output. Hope you can help.

thanks,
Ewald....

display flickers on mega

Hello!
If I connect the display to the arduino mega it flickers only.

DUE compatibility; if anyone have made a due_24_shield.h , please share

subject says all :)

When rotated, images are not displayed correctly

On my display, when I rotate, images are not diplayed correctly.
The rotationtest works flawless. But on tftbmp, only the non-rotated woofs display correctly. The rotated ones look "blurry". I am guessing the image needs to be read columns wise, not row wise, but I am not sure.

I used tftbmp to display just a single landscape image (bmpDraw()) and used tft.setRotation(1) before the draw. All inside setup(), loop() is empty. The image is messed up. Portrait images work like expected.
