     I managed to find a work around to generate the PDF and trigger a download via the browser instead and thought I should post incase anyone stumbles across this.

     //Create PDF in Bytes Uint8List pdfInBytes = pdf.save(); //Create blob and link from bytesfinal blob = html.Blob([pdfInBytes], 'application/pdf');final url = html.Url.createObjectUrlFromBlob(blob);final anchor = html.document.createElement('a') as html.AnchorElement ..href = url ..style.display = 'none' ..download = 'pdf.pdf';html.document.body.children.add(anchor); //Trigger the download of this PDF in the browser. RaisedButton( child: Text('Press'), onPressed: () { anchor.click(); Navigator.pop(context); }, )

   • sample active directory ldif file with apacheds

     Add the following (it's the minimal fragment of Microsoft's schema that contains sAMAccountName) at the beginning of users.ldif file:

     dn: cn=microsoft, ou=schemaobjectclass: metaSchemaobjectclass: topcn: microsoftdn: ou=attributetypes, cn=microsoft, ou=schemaobjectclass: organizationalUnitobjectclass: topou: attributetypesdn: m-oid=1.2.840.113556.1.4.221, ou=attributetypes, cn=microsoft, ou=schemaobjectclass: metaAttributeTypeobjectclass: metaTopobjectclass: topm-oid: 1.2.840.113556.1.4.221m-name: sAMAccountNamem-equality: caseIgnoreMatchm-syntax: 1.3.6.1.4.1.1466.115.121.1.15m-singleValue: TRUEdn: ou=objectclasses, cn=microsoft, ou=schemaobjectclass: organizationalUnitobjectclass: topou: objectClassesdn: m-oid=1.2.840.113556.1.5.6, ou=objectclasses, cn=microsoft, ou=schemaobjectclass: metaObjectClassobjectclass: metaTopobjectclass: topm-oid: 1.2.840.113556.1.5.6m-name: securityPrincipalm-supObjectClass: topm-typeObjectClass: AUXILIARYm-must: sAMAccountName[rest of users.ldif]

     Now add new objectClass to person entries:

     [...]dn: cn=rod,ou=people,dc=springframework,dc=orgobjectclass: topobjectclass: personobjectclass: organizationalPersonobjectclass: inetOrgPersonobjectclass: securityPrincipal <--- new objectClasscn: Rod Johnsonsn: JohnsonsAMAccountName: roduserPassword: koala[...]

     It's not enough to have new entries. ApacheDS' configuration in Spring Security has disabled schema interceptor, so new schema entries are not created by default. We can turn it on by creating BeanPostProcessor that fixes this:

     package com.example.test.spring;-import java.util.List;-import org.apache.directory.server.core.interceptor.Interceptor;import org.springframework.beans.BeansException;import org.springframework.beans.factory.config.BeanPostProcessor;import org.springframework.security.ldap.server.ApacheDSContainer;import static org.springframework.util.CollectionUtils.isEmpty;public class ApacheDSContainerConfigurer implements BeanPostProcessor { private List<Interceptor> interceptors; @Override public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException { if (bean instanceof ApacheDSContainer){ ApacheDSContainer dsContainer = ((ApacheDSContainer) bean); setInterceptorsIfPresent(dsContainer); } return bean; } private void setInterceptorsIfPresent(ApacheDSContainer container) { if (!isEmpty(interceptors)) { container.getService().setInterceptors(interceptors); } } @Override public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException { return bean; } public void setInterceptors(List<Interceptor> interceptors) { this.interceptors = interceptors; }}

     We have to register and configure bean in application context:

     <bean class="com.example.test.spring.ApacheDSContainerConfigurer"> <property name="interceptors"> <list> <bean class="org.apache.directory.server.core.normalization.NormalizationInterceptor"/> <bean class="org.apache.directory.server.core.authn.AuthenticationInterceptor"/> <bean class="org.apache.directory.server.core.referral.ReferralInterceptor"/> <!--<bean class="org.apache.directory.server.core.authz.AciAuthorizationInterceptor"/>--> <!--<bean class="org.apache.directory.server.core.authz.DefaultAuthorizationInterceptor"/>--> <bean class="org.apache.directory.server.core.exception.ExceptionInterceptor"/> <!--<bean class="org.apache.directory.server.core.changelog.ChangeLogInterceptor"/>--> <bean class="org.apache.directory.server.core.operational.OperationalAttributeInterceptor"/> <bean class="org.apache.directory.server.core.schema.SchemaInterceptor"/> <bean class="org.apache.directory.server.core.subtree.SubentryInterceptor"/> <!--<bean class="org.apache.directory.server.core.collective.CollectiveAttributeInterceptor"/>--> <!--<bean class="org.apache.directory.server.core.event.EventInterceptor"/>--> <!--<bean class="org.apache.directory.server.core.trigger.TriggerInterceptor"/>--> <!--<bean class="org.apache.directory.server.core.journal.JournalInterceptor"/>--> </list> </property></bean>

     It should be working now.

   • Sample with more samples at the begining and end of sample space

     Top Answer

     Answered Jul 18, 2019 · 3 votes

     This will give you more samples to the end of the intervall:

     np.sqrt(np.linspace(0,100,5))array([ 0. , 5. , 7.07106781, 8.66025404, 10. ])-

     You can choose a higher exponent to get more frequent intervalls towards the ends.

     To get more samples towards beginning and end of the intervall, make the original linspace symmetrical to 0 and then just shift it.

     General function:

     def nonlinspace(xmin, xmax, n=50, power=2): '''Intervall from xmin to xmax with n points, the higher the power, the more dense towards the ends''' xm = (xmax - xmin) / 2 x = np.linspace(-xm**power, xm**power, n) return np.sign(x)*abs(x)**(1/power) + xm + xmin

     Examples:

     >>> nonlinspace(0,10,5,2).round(2)array([ 0. , 1.46, 5. , 8.54, 10. ])>>> nonlinspace(0,10,5,3).round(2)array([ 0. , 1.03, 5. , 8.97, 10. ])>>> nonlinspace(0,10,5,4).round(2)array([ 0. , 0.8, 5. , 9.2, 10. ])

   So i have implemented my own algorithm ( its name is traprange ) to parse tabular data in pdf files. Following are some sample pdf files and results: Input file: sample-1.pdf, result: sample-1.html. Input file: sample-4.pdf, result: sample-4.html. Visit my project page at traprange.

   Code sample

   File pdf = new File("mypdf.pdf");

   String outfile = "mytxt.txt";

   String proc = "/usr/bin/pdftotext";

   ProcessBuilder pb = new ProcessBuilder(proc,"-layout",pdf.getAbsolutePath(),outfile);

   Let's assume that we have a text-based PDF document generated as an output by a piece of software. It contains tabular data, and we want to extract it and present in a digital format. There are two main ways to detect tables: 1. Manually, when you detect column borders by eye and mark table columns by hands 2. Automatically, when you rely on progra...
