我使用LibTiff.net来裁剪平铺Tiff的一部分并将其导出为平铺的Tiff,但遇到了"无法将平铺图像写入剥离图像的问题"。虽然" Tiff.open(" out.tif"," w")制作一个剥离图像,但如何创建一个平铺Tiff来填充输入数据呢?
using (Tiff input = Tiff.Open(@"E:\Sample_04.tif", "r"))
{
int width = input.GetField(TiffTag.IMAGEWIDTH)[0].ToInt();
int height = input.GetField(TiffTag.IMAGELENGTH)[0].ToInt();
int tileWidth = input.GetField(TiffTag.TILEWIDTH)[0].ToInt();
int tileLentgh = input.GetField(TiffTag.TILELENGTH)[0].ToInt();
int samplesPerPixel = input.GetField(TiffTag.SAMPLESPERPIXEL)[0].ToInt();
int bitsPerSample = input.GetField(TiffTag.BITSPERSAMPLE)[0].ToInt();
int photo = input.GetField(TiffTag.PHOTOMETRIC)[0].ToInt();
int config = input.GetField(TiffTag.PLANARCONFIG)[0].ToInt();
int tiles = 0;
int tileSize = input.TileSize();
byte[][] buffer = new byte[tileSize][];
int tileHeightCount = height / tileLentgh;
int tileWidthCount = width / tileWidth;
for (int y = 0; y < tileLentgh*5; y += tileLentgh)
{
for (int x = 0; x < tileWidth*5; x += tileWidth)
{
buffer[tiles] = new byte[tileSize];
input.ReadTile(buffer[tiles], 0, x, y, 0, 0);
tiles++;
}
}
// writing
using (Tiff output = Tiff.Open("out.tif", "w"))
{
output.SetField(TiffTag.SAMPLESPERPIXEL, samplesPerPixel);
output.SetField(TiffTag.IMAGEWIDTH, width );
output.SetField(TiffTag.IMAGELENGTH, height);
output.SetField(TiffTag.BITSPERSAMPLE, bitsPerSample);
output.SetField(TiffTag.ROWSPERSTRIP, output.DefaultStripSize(0));
output.SetField(TiffTag.PHOTOMETRIC, photo);
output.SetField(TiffTag.PLANARCONFIG, config);
int c = 0;
for (int y = 0; y < tileLentgh*5; y += tileLentgh)
{
for (int x = 0; x < tileWidth*5; x += tileWidth)
{
output.WriteTile(buffer[c], x, y, 0, 0);
c++;
}
}
}
}
System.Diagnostics.Process.Start("555.tif");
}
答案 0 :(得分:0)
要创建平铺的TIFF,请不要使用
output.SetField(TiffTag.ROWSPERSTRIP, output.DefaultStripSize(0));
在使用TiffTag.TILEWIDTH
方法之前,您绝对必须设置TiffTag.TILELENGTH
和WriteTile
字段。
