Add 'runall' target.
...
The ‘runall’ target runs the rotation on different sizes:
- 512x512
- 1024x1024
- 3000x3000
2014-07-24 22:17:55 +02:00
760d6244d0
Have different quantifications.
...
I now have a precise quantification for point position and a more
approximate one for pixel interpolation.

Change Point type to int64_t.

Add TPoint operators +=, -=, *=, /=
2014-07-24 00:40:27 +02:00
e7802e30fd
Compute src position in quantified coordinates.
...
Instead of relying on floating values for the position in the
source image, we quantify all positions with a power of 2.
We lose some precision and the delta step is less accurate, leading in
some offset at the end.
For now the rotation is not correct.
2014-07-23 23:44:14 +02:00

7e152c29fc
Add support for PGM format.
...
The code has been split into different source files.
This breaks for now rotation for tiled images and PPM format. The focus
is now on the PGM format.
2014-07-21 06:57:08 +02:00
53974a4116
Add PGM images of Lena of various sizes.
2014-07-20 13:14:51 +02:00

Clean Makefile indentation.
2014-07-16 22:07:30 +02:00
c918ca5504
Remove out-of-bounds check for tiled images.
...
Since tiles have an overlap, if the absolute point is inside the source
image, we can interpolate.
2014-07-16 21:50:25 +02:00

Implement RGBX for tiled images.
...
Interpolation is now done with SIMD with -DSIMD for tiled images as
well.
2014-07-16 20:44:32 +02:00
bcf16680ae
Remove RGBX structure.
...
The pixels are still packed as RGBX in memory but
no structure is created, it’s just a contiguous buffer.
Interpolation is now done with SIMD on integer values.
- Add SIMD define.
2014-07-16 02:08:32 +02:00
cce4d45ba6

Create small overlap in tiles.
...
Tiles overlap on the bottom line and the right column.
Having an overlap allows us to get neighbor points for each point in a
tile, regardless of its position.

049228b377
Fill a temp buffer for each line.
...
We don’t write into the memory right away, we first write to a temp
buffer that we blit into the rotated image.
2014-07-04 08:23:06 +02:00
e3e0d3c20a
Fix first rotated tile on each row.
...
The first tile on each row seemed to be missing values.
This was due to the ‘continue’ statement that would prevent
src_rotated_point to be incremented properly.
2014-07-04 00:34:06 +02:00
7f29bd192a
Pass tile to rotate_pixel() instead of image.
