Todo : find why STBI_ONLY_JPEG breaks Alignment mark

[nliaudat]

The Feature

As mentionned in #1721 ,STBI_ONLY_JPEG breaks alignment marks

STBI_ONLY_JPEG can save 2% of Flash

Todo :
debug the alignment marks to find why ClassFlowAlignment.h is linked to stb_image.h

I did not find why :
ClassFlowAlignment.h includes CAlignAndCutImage.h
CAlignAndCutImage.h includes CImageBasis.h (works if STBI_ONLY_JPEG enabled)
CImageBasis.h includes stb_image.h ( works if STBI_ONLY_JPEG enabled)

The images as seen in the Recognition page are stored on the sd-card as BMP images, see http://<IP>/fileserver/img_tmp/.

I guess thats the reason.

We should check with @jomjol what the reason to pick BMP is. Maybe it simply could be switched to JPG as well?

[jomjol]

Bitmaps are choosen, because I wanted to avoid lossed due to compression. If we would change the settings of the jpeg, that might work as well.

[caco3]

thanks!

I think if you set the jpeg compression to minimum it should be ok

[jomjol]

Would be needed to test.
BUT: if we remove the BMP option, we will loose the backward compatiblity, because up to now every image is stored as BMP.

[caco3]

I tested your PR #1789 and it works for me.

If it breaks the backwards compatibility,what impact does this have?
The recognition page seems to be ok after the first round.
And I like that the image are shown larger now.

[jomjol]

I checked everything and it does not break the backward compatility. I made a mistake while checking. So we can implement this change.

fixed in #1789
