--- Comment #12 from Tomaz Vajngerl <qui...@gmail.com> 2012-06-01 03:16:58 PDT --- Hi, I have already implemented Lanczos resampling but I need to test that the result is comparable to IrfanView. I will create a patch during weekend - with the resampling enabled only for PDF Export. Lanczos resampling uses separable convolution which has many other uses like alternative methods of resampling like BiCubic, Mitchell, ... but differ only on the kernel function. In the second step I will also implement those resampling methods. With separable convolution it is also possible to implement filters like Gaussian blur (smooth filter) and unsharpen masking,... Because the processing is separable (horizontal and vertical 1D convolution), it is also faster than currently implemented Gaussian Blur which uses 2D convolution. So in the third step I will replace Gaussian Blur with separable Gaussian Blur and implement some additional filters. Is it better to have for step 2 and 3 a new bugzilla entry or I should do everything under this bugzilla or what is your suggestion? I was searching the source code and did not find where resampling is done in Export function. Looks like I will have to debug like you suggested to find the correct place.
