Hello. I am trying to convert pdf to png. And i found this problems:
1. I don't need transparency. Document should stay white. If i turn -alpha off, i get corrupted document.
2. Border. If i set 1x1 border, for some unknown reasons all my document turn into big blue border.

Examples below:

Code: Select all

C:\imagemagick>convert.exe -resize "300x300>" -density 300 test.pdf test.png

Code: Select all

C:\imagemagick>convert.exe -resize "300x300>" -density 300 -background white -bo
rdercolor blue -border 1x1 test.pdf test.png

Code: Select all

C:\imagemagick>identify.exe -verbose test.pdf
