Hi,

I noticed that the image you included in your first example (toutou.png) is pretty big: 1533 × 1031. The files only 45 kb, but 1.5 Mb when is uncompressed (1533x1031=1.580.523). Maybe this is the reason TeXmacs is having so many problems when there are dozens of theses images. It runs out of memory. (I hope that I made the right reasoning.)

I noticed that Geoalbegra is able to export graphics to EPS. Maybe the solution is to use that format instead of PNGs. See http://wiki.geogebra.org/en/Export_Graphics_Dialog

hi and thanks to those how have tried my bugging files

i have an idea now

a simple .tm file with 100 linked images makes a texmacs crash at export

the images are 100 times the same .png geogebra picture

an other .tm file with 1200 linked images takes a few minuts for export

the images are 1200 times the same .png max os X screenshot

i deduce from this that there seems to be a problem with pictures exported by geogebra

my knowledges about pictures are not enough, however, to be able to formulate the problem in technical terms

if anyone of you has an idea how to ask the question on geogebra forum

geogebra pictures has .ps export problem themselves because of transparency

texmacs perfers .ps (thank you Martial) and geogebra prefers .png

i was just trying to work as fast and efficient as possible

i think that now, for each geogebra picture i want to insert into texmacs

- i export it to png

- i convert the png to ps with graphic converter

- i link the ps image in texmacs

are geogebra and texmacs borned to be enemys ? :-)

I tried your file with TexMacs (1.0.7.14)  on Linux (Ubuntu 9.04)

I changed the path of the png file, and produced a .ps file with preview (Ctr-P, then saved with ghostview) =>
very big file (~300 Mbytes)

Then, I converted the png file => eps (with Gimp : loaded as png then saved as eps)
I changed the .tm file, then preview => ps : much faster, and a final .ps much smaller (~23 Mbytes)


I works with TeXmacs every year (physics course) on a final big document (~ 300 pages) with many pictures, graphs, ... never had any problem with eps files.

hi all

i have put here

http://elodouwen.ouvaton.org/MYGOD/

an example

the .html file contains explanations

it is a very simple texmacs file with 99 times the same linked image (45Ko image)

99 is not a big number; in a book, 500 images (not so light all) is something quite possible.

i am very interested in your analysis

i will soon have to export some ps/pdf for editor

for the moment i can not do it

Sacha
