Hi, Working on converters, I had some ugly behavior with image rendering.
It appears that, inserting an image into TeXmacs leads, by default to a bad typesetting because the image is stretched by a factor approx 5/3. To reproduce it, copy paste : <image|http://upload.wikimedia.org/wikipedia/meta/6/6d/Wikipedia_wordmark_1x.png||||> In typeset_image () in src/Typeset/Concat/concat_active.cpp, I don't understand the line 318 : double pt= ((double) env->dpi*PIXEL) / 72.0; i) env->dpi is related to font's DPI and I don't know why should it imply image resizing. ii) I wonder if magnification should not play a role here. iii) I suppose that PIXEL is the ratio tmpt / px. iv) If we should translate the size from pixels to tmpt, I wonder why the calculus "pt= PIXEL * zoom_factor", following the documentation (length.en.tm), is wrong (at least, it gives a result very different than the current result). v) By the way, current calculus on my computer gives pt= 2133.33, (with default DPI= 600 and PIXEL= 256) whereas the "wanted size" of the picture is obtained with a pt approx 1280. Any suggest about this ?
