From eaf55aec004d24ba009756442dee6c5445e70695 Mon Sep 17 00:00:00 2001 From: vince damiani Date: Fri, 4 Nov 2016 16:37:01 +0100 Subject: [PATCH 1/6] multiple-files MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. Re-arranged html structure, used html5 features. 2. Added multiple images capability, images can be added one-by-one or selecting them with ctrl/cmd from the file dialog. 4. Output for multiple images can be represented by a single byte array or with a byte array for each images, its identifier will be increased with a trailing counter. 3. Added ‘GFXfontBitmap’ support. 4. Other smaller improvement.
