Re: [Pharo-users] JPEG export producing images with black background

by Olivier Auverlot

Hi Husman, A little piece of code to use an intermediate morph that has not a transparency background. When the morph is exported, the JPEG file is correct. |window m graph | window := ESExamples new kiviat2. graph := window model canvas imageForm asMorph. m := Morph new extent: graph extent; color: Color white. m addMorph: graph; position: 1@1. m imageForm writeJPEGfileNamed: 'test.jpg' We can probably do best Hope that can help you Olivier ;-) Le 16 juin 2013 Ã 09:49, Usman Bhatti a Ã©crit : > On Sun, Jun 16, 2013 at 12:00 AM, Benjamin <benjamin.vanryseghem.pharo(a)gmail.com> wrote: > use png. > > Jpegs have background, so you will not go very further in this direction (if I understood well your problem ^^) > > The thing is that I am using Artefact framework for PDF images and it uses JPEG plugin for embedding images.

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. After we will offer a web application where we can edit the code. But for now we are streamlining the process.

<<< have a look on git https://github.com/SquareBracketAssociates/PharoForTheEnterprise-english I started to convert all the zinc documentation that sven wrote. We can add a new chapter on Zinc Usage. We are working on a format that generates autoamtically PDF and html for the next books. Stef >>> What a cool idea!
