Bug ID: 65839
Summary: The resize method takes INFINITY, causing an infinite
loop
Product: POI
Version: 5.2.0-FINAL
Hardware: PC
OS: Mac OS X 10.1
Status: NEW
Severity: major
Priority: P2
Component: HSSF
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
When the image is damaged, the length and width value of the image is 0, and
the scale may change to INFINITY during calculation, causing the program to
loop endlessly
package org.apache.poi.hssf.usermodel;
@Override
public void resize(double scaleX, double scaleY) {
HSSFClientAnchor anchor = getClientAnchor();
anchor.setAnchorType(AnchorType.MOVE_DONT_RESIZE);
HSSFClientAnchor pref = getPreferredSize(scaleX,scaleY);
int row2 = anchor.getRow1() + (pref.getRow2() - pref.getRow1());
int col2 = anchor.getCol1() + (pref.getCol2() - pref.getCol1());
anchor.setCol2((short)col2);
// anchor.setDx1(0);
anchor.setDx2(pref.getDx2());
anchor.setRow2(row2);
// anchor.setDy1(0);
anchor.setDy2(pref.getDy2());
}
