convert png with transparency to eps3 file, -compress lzw
Posted: 2015-08-10T09:43:18-07:00
Hello,
this is the second bug:
start gimp, create a new image with 720x359 with alpha channel, fill the image with anything, check that there are no transparent pixels any more. Save the image as png file with transparency.
you will get a broken EPS file. Photoshop will produce a transparent box on the top left, ghostscript will refuse to load the file:
-> the image must have an alpha channel
-> the image must be exactly 720x359
-> RGB and alpha channel
-> there may not be any transparent pixels
I think the problem is related in LZWEncodeImage()
this is the second bug:

Code: Select all
convert 720x359-alpha.png -compress lzw eps3:/tmp/broken.epsCode: Select all
