C/C++ - Convertire immagini da bmp a jpg

11/07/07 14:10
Salve ho necessità di convertire un immagine bitmap a jpg.

Ho provato ad usare la libreria Cximage ma anche se ho scaricato la versione adatta al mio compilatore (microsoft visual c++ 8) non riesco a farla funzionare ottenendo infiniti messaggi di "unresolved external symbols" (anche se ho compilato e linkato tutte le librerie necessarie)

Qualcuno potrebbe consigliarmi un metodo funzionante con il compilatore che uso e magari anche semplice?
Grazie anticipatamente per la risposta

Ciao

se guardi Beatrix ha una funzione per covnertire le bmp in jpg, e usa anche la libreria jpeg.lib, se linkavi anche questa e ti da ancora errori prova ad aggiungere questo:

#pragma comment(lib,"CxImage/CxImage.lib"
#pragma comment(lib,"Jpeg/jpeg.lib"
tenendo le lib in cartelle chiamate CxImage e Jpeg allo stesso livello del progetto

Non ostante abbia linkato tali librerie e usato il medesimo codice continuo a ricevere milioni di questi errori:

posto sotto gli errori di compilazione forse potete aiutarmi 8-|

o il vs8 è incompatibile o ci deve essere qualche lib che fa conflitto.

Per curiosità prova a compilare beatrix, se non funziona neanche quello sono proprio le librerie che non vanno in questa versione di vs.

no non riesco a compilare neanche beatrix ho degli errori simili.

Non esiste qualche alternativa semplice e compatibile (si immagino che esista ma quale?)

grazie ancora per l'aiuto.

io ho risolto però uso una dll che non mi pare molto buona..è lemtissimo

cmq col devc++ ho aggiunto libjpg
è un po lungo il codice (2k) chi vuole il progetto mi può contattare :k:
il codice non l'ho fatto interamente io però va
