multiple problems on page rendering.

[guiann]

Hi !

I'm really interested in this project,

did you have good result so far ?

I cannot render pdf pages, it gives me a lot of

com.sun.pdfview.PDFParseException: Expected a number here. java.nio.BufferUnderflowException java.lang.NullPointerException

this is not crashing down the app but the page is never fully rendered : there is missing text or missing picture on each page and at random position...

can I send you a pdf file so you could try on it and maybe fix this problem ?

Unfortunately, this project mainly just wrapped an existing PDF rendering library so I don't know much about the internals. If you can attach a sample PDF or put it somewhere that I can download it, I'll be glad to take a look though and see if I can figure it out.

I have same problem. But it don't give exception. (In AlternateColorSpace class fcomp[3] is not available). Look at that class maybe solve your exception. My Solution is

AlternateColorSpace CLASS

Original Code

@Override
public int toColor(float[] fcomp) {

    float average = 0;
    if (function != null) {
        // translate values using function
        fcomp = function.calculate(fcomp);
    }
    float k = fcomp[3];
    float w = 255 * (1 - k);
    float r = w * (1 - fcomp[0]);
    float g = w * (1 - fcomp[1]);
    float b = w * (1 - fcomp[2]);
    return Color.rgb((int) r, (int) g, (int) b);
}

My Code

@Override
public int toColor(float[] fcomp) {

    float average = 0;
    float k;
    if (function != null) {
        // translate values using function
        fcomp = function.calculate(fcomp);
    }
    //checks fcomp lenght...
    if (fcomp.length <= 3) {
        //this is not a good solution
        k = 1;
    }
    float w = 255 * (1 - k);
    float r = w * (1 - fcomp[0]);
    float g = w * (1 - fcomp[1]);
    float b = w * (1 - fcomp[2]);
    return Color.rgb((int) r, (int) g, (int) b);
}

Finally i found the problem. It is like a joke.

PdfViewerActivty

Original code

line 78

public static final boolean DEFAULTKEEPCACHES = false;

My Code

line 78

public static final boolean DEFAULTKEEPCACHES = true;

solves my problem.

@jblough thank you very much for all of your work.

if you change DEFAULTKEEPCACHES to true, you will have OutOfMemory issue.

I included the PdfViewer.jar in my project and extended, so I only have the .class and I can't make the change in there. Please how do I change the DEFAULTKEEPCACHES to true. I'm sorry if this question is trivial.
