20031030 Laurent G. Beaudet - Corrected the computation of height vs width
Please don't delete names in the script. Thanks.
This class creates a thumbnail of an image. Size of thumbnail is determined with maximum width and height of an thumbnail.
*/
// ==========================================================================================
// Changings: by Gotti
// Purpose of changes: If thumb with same size already exists we don't need to write it again.
// Support for GD1 added.
// GD does not support .gif so we handle them as .jpg
// Added missing function 'imagedestroy()'
// Changed lines: 135-146, 165-170, 199
// Homepage: http://www.mambo.i-d-sign.com
// Author: Gotti
// Date: 10.02.2004

Tessuto non Tessuto NOSTRA PRODUZ. |

Utilizzando il Polimero Polipropilene, una delle resine più versatili oggi prodotte, la nostra tecnologia consente di ottenere un TESSUTO NON TESSUTO dalle eccellenti caratteristiche, da non trascurare il fatto che è un prodotto di NOSTRA PRODUZIONE
Clicca qui per vedere le macchine con cui lo produciamo
Il Polimero Polipropilene allo stato solido viene fuso e, tramite un estrusione, spinto attraverso speciali "filiere" dotate di fori sottilissimi; da questi escono sottili filamenti continui che, dopo il raffreddamento, vengono depositati su di un nastro trasportatore fino a formare un tappeto continuo ed omogeneo. Questo tappeto viene poi sottoposto all'azione simultanea di temperatura e pressione affinché i singoli filamenti si saldino tra di loro: ciò genera una superficie tessile di varie grammature, morbida e molto resistente, dalle infinite applicazioni. |
