Subject: Scale transformation of images
Date: Sun, 16 Jun 2019 09:16:36 +0300 [thread overview]
Message-ID: <8475F4F0-00E8-44A9-BD60-6D3894E86EB0@gnu.org> (raw)
If I insert an image into a buffer with insert-image, and then position point on the image and press '-' to make it smaller, the scale factors I see in the transform matrix are greater than 1. This is because image_set_size does this:
double xscale = img->width / (double) width;
and similarly for yscale. Shouldn't we divide width by img->width instead?
