Re: Urgent...Image compression!

I am using Leadtools 15 .! how can i compress tiff file ?

I have tried to use this command but the size is still too big.

codecs.Save(image, filename, RasterImageFormat.Tif,
8, 1, image.PageCount, 1, Leadtools.Codecs.CodecsSavePageMode.Overwrite);

let suppose if you have file it size 2.7 MB after compression how should be it size?

please help me, and if you have a code tha't more wonderful..

a waiting your replay

I understand from your code that you want to save as 8-bit
(grayscale or color) TIF. However, using the RasterImageFormat.Tif file type saves images as TIF without compression.

To save as compressed 8-bit TIF, then you can use any of these constants:

1. TifLzw (LZW Compression and RGB color space)

2. TifJpeg (JPEG compression and YUV 4:4:4 color space Lossless)

3. TifJpeg422 (JPEG compression and YUV 4:2:2 color space)

4. TifJpeg411 (JPEG compression and YUV 4:1:1 color space)

5. TifCmp (CMP Compression)

6. TifJbig (JBIG Compression)

7. TifJ2k (JPEG 2000 Compression)

8. TifCmw (Wavelet CMP Compression)

There are also other compressed TIFF sub-types but they work with bits per pixel values other than 8.

For more details, please read the help topic "File Formats: TIFF (Tagged Image File Format)" in the Raster .NET help file.
