2004.09.01 05:23 "DPI setting", by <poom@kosugi-msoft.jp>
Hi,
Now I can generate TIFF file .However,when I check my tiff file
with photoshop,my picture's DPI value is strange!
On setting tag ,I setted like this.
TIFFSetField(tif, TIFFTAG_IMAGEWIDTH, imageW);
TIFFSetField(tif, TIFFTAG_IMAGELENGTH, imageH);
TIFFSetField(tif, TIFFTAG_BITSPERSAMPLE, 8,8,8);
TIFFSetField(tif, TIFFTAG_SAMPLESPERPIXEL, 3);
int rowperstrip =TIFFDefaultStripSize(tif, imageW*3);
TIFFSetField(tif, TIFFTAG_ROWSPERSTRIP, rowperstrip);
TIFFSetField(tif, TIFFTAG_COMPRESSION, 1);
TIFFSetField(tif, TIFFTAG_PHOTOMETRIC,PHOTOMETRIC_RGB);
TIFFSetField(tif, TIFFTAG_PLANARCONFIG, PLANARCONFIG_CONTIG);
TIFFSetField(tif, TIFFTAG_XRESOLUTION,300);
TIFFSetField(tif, TIFFTAG_YRESOLUTION,300);
TIFFSetField(tif, TIFFTAG_RESOLUTIONUNIT, RESUNIT_INCH);
But resulted TIFF file 's DPI was 72 .
I try to correct this problem but now I can't found the way.
Please tell me the right way to solve it.
Thank you so much
