Image editor PNG
Ik had zelf een PHP/Ajax based imageeditor gedownload. Nu heb ik uren ervoor nodig gehad om het in te bouwen in mijn systeem, nu heb ik het dan eindelijk werken.
Echter support dit systeem alleen JPEG, dus dacht ik, ik haal het betreffende stuk uit het bestand, en plaats het in image.jpeg.php. Ik koppieerde het, naar image.png.php en replaced alle jpeg tot png. In het hoofd bestand controlleerde ik dan de image op de mimetype en include zo het juiste bestand. Helaas is het in praktijk niet zo makkelijk.
JPEG werkt nogsteeds uitstekend, maar png wil niet werken. Dit is de source:
