El método ayuda a que las resoluciones horizontales y verticales sean iguales.
public void AlignResolutions()CopyFrame(TiffFrame)
Copia todo el marco (duplicado).
public static TiffFrame CopyFrame(TiffFrame tiffFrame)Parameters
tiffFrame TiffFrame
El cuadro tiff para copiar.
Returns
El recién copiado tiff frame.
CreateFrameFrom(TiffFrame y TiffOptions)
Crea el marco de la tiffFrame’ especificada utilizando las opciones especificadas.Los datos de pixel se conservan pero se converten en el formato deseado.
public static TiffFrame CreateFrameFrom(TiffFrame tiffFrame, TiffOptions options)Parameters
tiffFrame TiffFrame
El marco tiff para crear de.
options TiffOptions
Las nuevas opciones a utilizar.
Returns
El nuevo marco creado.
Examples
El siguiente ejemplo muestra cómo crear una copia de grayscale de un marco existente y agregarlo a una imagen TIFF.
string dir = "c:\\temp\\";
Aspose.Imaging.ImageOptions.TiffOptions createTiffOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
// Create a permanent, not temporary file source.
createTiffOptions.Source = new Aspose.Imaging.Sources.FileCreateSource(dir + "multipage.tif", false);
createTiffOptions.Photometric = Aspose.Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.Rgb;
createTiffOptions.BitsPerSample = new ushort[] { 8, 8, 8 };
using (Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)Image.Create(createTiffOptions, 100, 100))
{
// The linear gradient from the left-top to the right-bottom corner of the image.
Aspose.Imaging.Brushes.LinearGradientBrush brush =
new Aspose.Imaging.Brushes.LinearGradientBrush(
new Aspose.Imaging.Point(0, 0),
new Aspose.Imaging.Point(tiffImage.Width, tiffImage.Height),
Aspose.Imaging.Color.Red,
Aspose.Imaging.Color.Green);
// Fill the active frame with a linear gradient brush.
Aspose.Imaging.Graphics gr = new Aspose.Imaging.Graphics(tiffImage.ActiveFrame);
gr.FillRectangle(brush, tiffImage.Bounds);
// Grayscale options
Aspose.Imaging.ImageOptions.TiffOptions createTiffFrameOptions = new Aspose.Imaging.ImageOptions.TiffOptions(Aspose.Imaging.FileFormats.Tiff.Enums.TiffExpectedFormat.Default);
createTiffFrameOptions.Source = new Aspose.Imaging.Sources.StreamSource(new System.IO.MemoryStream());
createTiffFrameOptions.Photometric = Imaging.FileFormats.Tiff.Enums.TiffPhotometrics.MinIsBlack;
createTiffFrameOptions.BitsPerSample = new ushort[] { 8 };
// Create a grayscale copy of the active frame.
// The pixel data is preserved but converted to the desired format.
Aspose.Imaging.FileFormats.Tiff.TiffFrame grayscaleFrame = Aspose.Imaging.FileFormats.Tiff.TiffFrame.CreateFrameFrom(tiffImage.ActiveFrame, createTiffFrameOptions);
// Add the newly created frame to the TIFF image.
tiffImage.AddFrame(grayscaleFrame);
tiffImage.Save();
}Crop(Rectangle)
Crotando la imagen.
public override void Crop(Rectangle rectangle)Parameters
rectangle Rectangle
El rectángulo.
GetOriginalOptions()
Obtenga las opciones basadas en las configuraciones de archivo original.Esto puede ser útil para mantener la profundidad del bit y otros parámetros de la imagen original sin cambios.Por ejemplo, si cargamos una imagen de PNG en blanco y negro con 1 bito por píxel y luego la guardamos utilizando elAspose.Imaging.DataStreamSupporter.Save(System.String) método, la imagen PNG de salida con 8 bits por pixel se producir.Para evitarlo y ahorrar la imagen PNG con 1 bits por píxel, utilice este método para obtener las opciones de ahorro correspondientes y pasarlaspara el método Aspose.Imaging.Image.Save(System.String,Aspose.Imaging.ImageOptionsBase) como el segundo parámetro.
public override ImageOptionsBase GetOriginalOptions()Returns
Las opciones basadas en las configuraciones de archivo original.
ReleaseManagedResources()
Asegúrese de que los recursos no gestionados no se liberan aquí, ya que pueden haber sido ya liberados.
protected override void ReleaseManagedResources()RemoveMetadata()
Elimina estos metadatos de instancia de la imagen al configurar los valores de Aspose.Imaging.Xmp.IHasXMPData.xmpDat y Wl17.Exif. Nula.
public override void RemoveMetadata()Resize(int, int, resizeType)
Recupera la imagen.
public override void Resize(int newWidth, int newHeight, ResizeType resizeType)Parameters
newWidth int
La nueva amplitud.
newHeight int
La nueva altura.
resizeType ResizeType
El tipo de residuos.
Rotate(float, bool, color)
Imagen rotativa alrededor del centro.
public override void Rotate(float angle, bool resizeProportionally, Color backgroundColor)Parameters
angle float
El ángulo de rotación en grados. valores positivos rotarán de manera horaria.
resizeProportionally bool
si se establece a ‘verdad’ tendrás su tamaño de imagen cambiado de acuerdo con las proyecciones rectangulares rotadas (puntos de esquina) en otro caso que deja las dimensiones no tocadas y sólo los contenidos de la imagen interna son rotados.
backgroundColor Color
El color del fondo.
SaveData(Stream)
ahorrar los datos.
protected override void SaveData(Stream stream)Parameters
stream Stream
El flujo para salvar los datos a.
UpdateDimensions(El int, int)
Actualizar las dimensiones de la imagen.
protected override void UpdateDimensions(int newWidth, int newHeight)Parameters
newWidth int
La nueva imagen es amplia.
newHeight int
El nuevo tamaño de la imagen.
