Converting image

As our Designer was fired because of crisis - I had to change images size. So imagemagic is excelent for this use.

mogrify -gravity Center -crop 30X22+0+0 *.png
mogrify -format png *.jpg
mogrify -resize 30x22+0+0 *.*
mogrify -resize 120% *.*

identify -format "%wx%h \n" *.*


Hibernate Custom Type

Database has for example wrong state and can't save 1 or 0, 'Y' or 'N', 'YES' or 'NO'
So you need to save state as 1 and 2. Seems that database need refactoring... yes you are right but if you can't? Here is decision - custom type

package com.types;

import java.io.Serializable;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;

import org.hibernate.HibernateException;
import org.hibernate.usertype.UserType;

public class OneTwoBooleanType implements UserType{

private final static int DB_TRUE = 1;
private final static int DB_FALSE = 2;

public Object assemble(Serializable cached, Object owner) throws HibernateException {
return cached;
}

public Object deepCopy(Object value) throws HibernateException {
return value;
}

public Serializable disassemble(Object value) throws HibernateException {
return (Serializable) value;
}

public boolean equals(Object x, Object y) throws HibernateException {
if(x==null){
return false;
}
return ((Boolean)x).equals(y);
}

public int hashCode(Object x) throws HibernateException {
return x.hashCode();
}

public boolean isMutable() {
return false;
}

public Object nullSafeGet(ResultSet rs, String[] names, Object owner) throws HibernateException, SQLException {
Number val = (Number) rs.getObject(names[0]);
if(val==null){
return false;
}
return val.intValue() == DB_TRUE ? true : false;
}

public void nullSafeSet(PreparedStatement st, Object value, int index) throws HibernateException, SQLException {
int dbValue;
if(value==null){
dbValue = DB_FALSE;
} else {
dbValue = (Boolean) value ? DB_TRUE : DB_FALSE;
}
st.setInt(index, dbValue);
}

public Object replace(Object original, Object target, Object owner) throws HibernateException {
return original;
}

public Class returnedClass() {
return Boolean.class;
}

public int[] sqlTypes() {
return new int[]{Types.SMALLINT};
}

}

And It's usage

@Column(name="INTERNAL_STATUS_ID")
@Type(type="com.types.OneTwoBooleanType")
private boolean isVisible;
