Poor Quality of EPS file

Hi,
I am using followings commands for converting a TIFF file to EPS file:
convert -alpha off -strip tiffile.tif[0] -density 100 epsfile.eps
convert -alpha off -strip tiffile.tif[0] -resample 100 epsfile.eps
I have tried above commands but no command produced epsfile.eps file with resolution 100X100. The above commands produced a result with 72X72 resolution. And the produced eps file is like an x-ray image.
Note: When I am applying profile to this file, then EPS file is produced with good quality. But I want this EPS file generation without applying any profile

You are putting a raster file into an eps vector shell. EPS is normally a vector format. But with a raster file imbedded it will be the same as the raster file. When displaying the eps file you will need to define a new density in order for it, since it has no implicit density or resize the tif file first before converting it.
This works for me
convert rose: rose.eps
Now compare
display rose:
to
display -density 400 rose:
The latter is larger.

Hi,
For converting a TIFF file to EPS file I have used the following command:
convert -alpha off -strip -resample 150 TEST_0201_2.tif[0] -profile /tmp/ICCProfiles/Recommended/USWebCoatedSWOP.icc -profile "/tmp/ICCProfiles/Recommended/sRGB Color Space Profile.icm" /tmp/TestFiles/tif_test_tif_resample_temp_1.eps
When I used this command to generate a EPS file, I was able to find two files in the destination folder having "-0" or "-1"(tif_test_tif_resample_temp_1-0.eps & tif_test_tif_resample_temp_1-1.eps). And one of the file is a
blank white screen and other is the
xray image of the Tiff file.
When I used the below command I am able to produce only one file as output, but the output EPS file looks like a x-ray image:
convert -alpha off -strip -resample 150 -background White TEST_0201_1.tif -profile /tmp/ICCProfiles/Recommended/USWebCoatedSWOP.icc -profile "/tmp/ICCProfiles/Recommended/sRGB Color Space Profile.icm" -flatten /e2/tiftoepsconverter.eps
I have taken the screen shot of the EPS generated. Please find the screenshot in the below link:

Thanks in advance...............

convert -alpha off -strip -resample 150 TEST_0201_2.tif[0] /tmp/ICCProfiles/Recommended/USWebCoatedSWOP.icc -profile "/tmp/ICCProfiles/Recommended/sRGB Color Space Profile.icm" /tmp/TestFiles/tif_test_tif_resample_temp_1.eps
The command is badly formed.
You should read the input, process it, then write it.
You put /tmp/ICCProfiles/Recommended/USWebCoatedSWOP.icc in the place where IM expects an input image. So it reads it as an image, which is why it writes two output images.
A better command would be:
Code: Select all
convert ^
TEST_0201_2.tif[0] ^
-alpha off -strip -resample 150 ^
-profile /tmp/ICCProfiles/Recommended/USWebCoatedSWOP.icc ^
-profile "/tmp/ICCProfiles/Recommended/sRGB Color Space Profile.icm" ^
/tmp/TestFiles/tif_test_tif_resample_temp_1.eps
(Windows syntax, so line-continuation character is "^").
Can you put your input tiff somewhere like dropbox.com and post the URL here?

Thanks snibgo, I have run wrong command. Now I have updated the command.
convert -alpha off -strip -resample 150 TEST_0201_2.tif[0] -profile /tmp/ICCProfiles/Recommended/USWebCoatedSWOP.icc -profile "/tmp/ICCProfiles/Recommended/sRGB Color Space Profile.icm" /tmp/TestFiles/tif_test_tif_resample_temp_1.eps
Its working on machine having ImageMagick - 6.8.7-5 and not working on machine having ImageMagick - 6.5.4-7
Is there any solution for making it to work with ImageMagick - 6.5.4-7

v6.5.4 is very old. Perhaps "-profile" worked differently then. I suppose the input tiff is CMY or CMYK, and perhaps "-colorspace" will help.
Can you put your input tiff somewhere like dropbox.com and post the URL here?

As these files are customer specific files. I could not give those files to you........

convert -alpha off -strip -resample 150 TEST_0201_2.tif[0] -profile /tmp/ICCProfiles/Recommended/USWebCoatedSWOP.icc -profile "/tmp/ICCProfiles/Recommended/sRGB Color Space Profile.icm" /tmp/TestFiles/tif_test_tif_resample_temp_1.eps
I think this command is still wrong. You should read the tif file first, then turn alpha off and resample after converting with profiles. Try
convert TEST_0201_2.tif[0] -alpha off -strip -profile /tmp/ICCProfiles/Recommended/USWebCoatedSWOP.icc -profile "/tmp/ICCProfiles/Recommended/sRGB Color Space Profile.icm" -resample 150 /tmp/TestFiles/tif_test_tif_resample_temp_1.eps
