Earlier, I tried with exporting PNGs (that have a transparent background) but when importing these PNGs into pdf docs, the JPEGReader adds the colored background (black in my case). Another solution would be to see if Artefact can allow embedding Forms in Pharo into PDF docs directly (currently it does not) or it can provide a plugin for PNG images. > > Ben > > On Jun 15, 2013, at 11:56 PM, Usman Bhatti <usman.bhatti(a)gmail.com> wrote: > > I need to export JPEG images in Pharo to later import then in my PDF > document.

use png. Jpegs have background, so you will not go very further in this direction (if I understood well your problem ^^) Ben On Jun 15, 2013, at 11:56 PM, Usman Bhatti <usman.bhatti(a)gmail.com> wrote: > I need to export JPEG images in Pharo to later import then in my PDF document.

JPEG export producing images with black background

by Usman Bhatti

I need to export JPEG images in Pharo to later import then in my PDF document. When I export JPEG files with Pharo, the background is black, which makes the exported image meaningless. To reproduce the problem, do the following in the latest moose image (the image can be obtained from here<https://ci.inria.fr/moose/job/moose-latest-dev-4.8/> ): |window| window := ESExamples new kiviat2. window model canvas imageForm writeJPEGfileNamed: 'fileName.jpg'. The file will be produced in the image folder. If someone could suggest how to make the background white or transparent, it'll be a great help. Usman

So, just to be clear, if I wanted to help, all i would have to do is fork the repo, write / improve a section and then issue a pull request? yes We can also add you as a contributor.

I'm working (I should do another pass) on a minimal logging framework that the the compiler should be able to use and that the user gets presented with a list of log objects such as this references to unknown variables. In fact I started a object logging framework just because of this poor approach. I hate transcript and strings just for this unstructured and stupid behavior (you have to open the transcript before else â¦. :) Stef so I will kick myself and restart to work on it. > > Thanks > > Paul > > > > On 06/15/2013 01:02 AM, StÃ©phane Ducasse wrote: >> Hi Paul >> >> what was doing the recompile?

Re: [Pharo-users] recompile a class via menu item in Pharo 2?

by Paul DeBruicker

Hi Stef, I would recompile a class or "class with subclasses" hierarchy manually with the Transcript open after removing an inst var definition from a class to see if I left any references to the inst var. The 'recompile' menu option only appeared once you had limited the refactoring scope in some way.
