}Crop(Rectangle)
Scopri l’immagine.
public override void Crop(Rectangle rectangle)Parameters
rectangle Rectangle
Il rectangolo .
GetOriginalOptions()
Riceve le opzioni in base alle impostazioni del file originale.Questo può essere utile per mantenere la profondità del bit e altri parametri dell’immagine originale invariati.Ad esempio, se caricamo un’immagine PNG in bianco e nero con 1 bit per pixel e lo salviamo utilizzando ilAspose.Imaging.DataStreamSupporter.Save(System.String) méthode, l’image PNG de sortie avec 8 bits par pixel sera produite.Per evitare e salvare l’immagine PNG con 1 bit per pixel, utilizzare questo metodo per ottenere le opzioni di risparmio corrispondenti e passare loroà la méthode Aspose.Imaging.Image.Save(System.String,_Wl17. ImageOptionsBase) comme deuxième paramètre.
public override ImageOptionsBase GetOriginalOptions()Returns
Le opzioni basate sulle impostazioni del file originale.
ReleaseManagedResources()
Assicurati di non rilasciare risorse non gestite qui, poiché potrebbero essere già state rilasciate.
protected override void ReleaseManagedResources()RemoveMetadata()
Supprimer les métadonnées de cette image en définissant ces valeurs Aspose.Imaging.Xmp.IHasXMPData.xmpDate et VL16 .Exif.IhasExivDato.ExIFDat à Null.
public override void RemoveMetadata()Resize(int, int, resizeType)
Ristrutturare l’immagine.
public override void Resize(int newWidth, int newHeight, ResizeType resizeType)Parameters
newWidth int
La nuova larghezza.
newHeight int
La nuova altezza.
resizeType ResizeType
Il tipo di ritorno.
Rotate(fleat, bool, couleur)
Immagini girate intorno al centro.
public override void Rotate(float angle, bool resizeProportionally, Color backgroundColor)Parameters
angle float
L’angolo di rotazione in gradi. valori positivi gireranno in orologio.
resizeProportionally bool
se impostato a ’true’ avrai la dimensione dell’immagine modificata in base alle proiezioni rettangoli rotate (punti angolare) in caso diverso che lascia le dimensioni non toccate e solo i contenuti dell’immagine interna sono rotati.
backgroundColor Color
Il colore del background.
SaveData(Stream)
Économisez les données.
protected override void SaveData(Stream stream)Parameters
stream Stream
Le flux pour sauvegarder les données.
UpdateDimensions(int, int)
