[RESOLVED] GRRLIB_ScrShot output does not contain hole screen
Hello,
I face the following problem with the GRRLIB_ScrShot() method. I have a wide screen LCD television. When i call the GRRLIB_ScrShot( ) method the output contains a PNG file with 640x480 pixels but i miss the lower part of the screen.
See the following picture as example http://www.plaatsoft.nl/wiibrew/wp-cont … 165333.png
Is this a bug?

Ho NoNameNo,
No difference with the normal (wide screen disabled) tv mode. Still missing the lower part of the png image.

PAL / NTSC? 50hz / 60hz?
There are so many different video modes.. but you can try the following:
In the GRRLIB.c, find this line:
Code:
ErrorCode = PNGU_EncodeFromYCbYCr(pngContext, 640, 480, xfb[fb], 0);
and change it to:
Code:
ErrorCode = PNGU_EncodeFromYCbYCr(pngContext, rmode->fbWidth, rmode->efbHeight, xfb[fb], 0);

Hi Xane,
Your code adaption works fine. The picture format is now 640x528 pixels and contains the complete screen! Thanks!

What is the difference between:
ErrorCode = PNGU_EncodeFromYCbYCr(pngContext, rmode->fbWidth, rmode->efbHeight, xfb[fb], 0);
And using this:
errorCode = PNGU_EncodeFromYCbYCr(pngContext, rmode->viWidth, rmode->viHeight, xfb[fb], 0);
