Hallo
Another try. I added some debug output to the source. If I have exposure
blinking enabled and try to rotate counter clockwise
(one click - so one degree), I get the following output:
X. Scale [0.262622], img-w [619], rot-w [2357] Y. Scale [0.263068], img-h
[926], rot-h [3520]
X: [617], CropX2: [2347] Y: [923], CropY2: [3505]
X. Scale [0.397971], img-w [1412], rot-w [3548] Y. Scale [0.176397], img-h
[423], rot-h [2398]
X: [935], CropX2: [2347] Y: [423], CropY2: [3505]
The corresponding function looks like this:
void ufraw_get_scaled_crop(ufraw_data *uf, UFRectangle *crop)
{
ufraw_image_data *img = ufraw_get_image(uf, ufraw_transform_phase, FALSE);
float scale_x = ((float)img->width) / uf->rotatedWidth;
float scale_y = ((float)img->height) / uf->rotatedHeight;
printf("X. Scale [%f], img-w [%d], rot-w [%d] ", scale_x, img->width,
uf->rotatedWidth);
printf("Y. Scale [%f], img-h [%d], rot-h [%d]\n", scale_y, img->height,
uf->rotatedHeight);
crop->x = MAX(floor(uf->conf->CropX1 * scale_x), 0);
int x2 = MIN(ceil(uf->conf->CropX2 * scale_x), img->width);
crop->width = x2 - crop->x;
crop->y = MAX(floor(uf->conf->CropY1 * scale_y), 0);
int y2 = MIN(ceil(uf->conf->CropY2 * scale_y), img->height);
crop->height = y2 - crop->y;
printf("X: [%d], CropX2: [%d] ", x2, uf->conf->CropX2);
printf("Y: [%d], CropY2: [%d]\n", y2, uf->conf->CropY2);
}
Why on earth does the values for scale_x and scale_y change that drastic?
