Example 31 with PackagePart

use of org.apache.poi.openxml4j.opc.PackagePart in project poi by apache.

the class XWPFPictureData method equals.

@Override

    /*
         * In case two objects ARE equal, but its not the same instance, this
         * implementation will always run through the whole
         * byte-array-comparison before returning true. If this will turn into a
         * performance issue, two possible approaches are available:<br>
         * a) Use the checksum only and take the risk that two images might have
         * the same CRC32 sum, although they are not the same.<br>
         * b) Use a second (or third) checksum algorithm to minimise the chance
         * that two images have the same checksums but are not equal (e.g.
         * CRC32, MD5 and SHA-1 checksums, additionally compare the
         * data-byte-array lengths).
