Joseph Vychtrle commented on TIKA-689:
--------------------------------------
You're right Nick, although I got it working, I don't know what was the reason,
because I always tracked the file path of FileInputStream in debugger and
opened it with open office Impress. Simple text file wouldn't be opened with it.
> MimeTypes detector detects text/plain content type of a PPT file
> ----------------------------------------------------------------
>
> Key: TIKA-689
> URL: https://issues.apache.org/jira/browse/TIKA-689
> Project: Tika
> Issue Type: Bug
> Components: mime
> Affects Versions: 0.9, 1.0
> Reporter: Joseph Vychtrle
> Labels: MimeTypes,
>
> If I create a PPT file like this
> {code}
> import org.apache.poi.hslf.model.Slide;
> import org.apache.poi.hslf.model.TextBox;
> import org.apache.poi.hslf.usermodel.RichTextRun;
> import org.apache.poi.hslf.usermodel.SlideShow;
> private void createPPTDocument(String from, File file) throws Exception
> {
> SlideShow ppt = new SlideShow();
> Slide slide = ppt.createSlide();
> TextBox shape = new TextBox();
> RichTextRun rt = shape.getTextRun().getRichTextRuns()[0];
> shape.setText(from);
> rt.setFontSize(7);
> slide.addShape(shape);
> shape.setAnchor(new java.awt.Rectangle(50, 50, 500, 300));
> //position of the text box in the slide
> slide.addShape(shape);
> FileOutputStream out = new FileOutputStream(file);
> ppt.write(out);
> out.close();
> }
> {code}
> And then :
> {code}
> MediaType mediaType = MediaType.parse(tika.detect(is));
> {code}
> It results in text/plain, MimeTypes detector used, the magic header simply
> doesn't match and then it falls back to text/plain.
