Well I'm having some troubles when creating new pages.
I get my data from a query.
Sorry if I post a lot of code, but it's all needed and I'm not sure how to do a MCVE as I'm pretty new at working with PDF.
This issue is:
Before writing next block of code I check current Y coord, I can achieve this, but when I need to create new Page and start writing again, well happens this
Here are the codes used in the PDF:
public float checkContentStream(float y) throws Exception {
float newY = checkYCoord(y, 3, 10);
if (newY == 700) {
if (content != null) {
content.close();
}
File file = new File(logoPath);
PDJpeg logoImg = new PDJpeg(doc, new FileInputStream(file));
PDPage page = new PDPage(PDPage.PAGE_SIZE_LETTER);
doc.addPage(page);
content = new PDPageContentStream(doc, page);
content.drawImage(logoImg, 50, 720);
rHeader();
}
return newY;
}
This method checks if reached BOTTOM MARGIN = 60
private float checkYCoord(float y, int lines, int space) {
float newY = y;
for (int i = 0; i < lines; i++) {
if ((newY - space) <= BOTTOM_MARGIN) {
newY = 700f;
return newY;
} else {
newY = newY - space;
}
}
return y;
}
This method does the same as 1st but used both, I know I shouldn't and must not use hardcoded values, like 10 or 3.
public float checkContentStream(float y, int lines, int space) throws Exception {
float newY = checkYCoord(y, lines, space);
if (newY == 700) {
if (content != null) {
content.close();
}
File file = new File(logoPath);
PDJpeg logoImg = new PDJpeg(doc, new FileInputStream(file));
PDPage page = new PDPage(PDPage.PAGE_SIZE_LETTER);
doc.addPage(page);
content = new PDPageContentStream(doc, page);
content.drawImage(logoImg, 50, 720);
rHeader();
}
}
public float rText(float x, float y, int space, String labelField, String value, int fieldSize) throws Exception {
if(fieldSize == 1){
return rText(x, y, space, labelField, value, FIELD_WIDTH, VALUE_WIDTH);
}
else{
if(fieldSize == 2){
return rText(x, y, space, labelField, value, FIELD_WIDTH, DESC_WIDTH);
}
else{
return rText(x, y, space, labelField, value, FIELD_WIDTH, TEXT_WIDTH);
}
}
}
I'm almost sure the error comes from this method:
public float rText(float x, float y, int space, String labelField, String value, int fieldWidth, int valueWidth) throws Exception {
PDFont font = PDType1Font.TIMES_BOLD;
content.setFont(font, 9);
float y1 = 0f;
float y2 = 0f;
//y = y >= 700 ? 700 : checkContentStream(y, 3, 10);
if (value == null) {
//y = checkYCoord(y, 1, 10);
return rText(labelField, fieldWidth, x, y - 19, space, font, false);
}else {
//y = checkYCoord(y, 3, 10);
y1 = rText(labelField, fieldWidth, x, y - 20, space, font, false);
font = PDType1Font.TIMES_ROMAN;
content.setFont(font, 9);
y = checkYCoord(y, 3, 10); // Comment / Uncoment this line
y2 = rText(value, valueWidth, x + fieldWidth + 10, y - 20, space, font, true);
if (y1 >= y2) {
return y2;
} else {
return y1;
}
}
}
This method paints text
private float rText(String text, int width, float x, float y, int space, PDFont font, boolean isValue) throws Exception {
float newY = y;
int rowHeight = 0;
ArrayList<String> rowList = getRows(text, width, font);
if(isValue){
newY = checkContentStream(newY);
newY = newY == 700 ? 680 : newY;
for (String row : rowList) {
if(rowHeight >= 10){
newY = checkContentStream(newY - 10);
newY = newY == 700 ? 680 : newY;
}
else{
newY = checkContentStream(newY);
newY = newY == 700 ? 680 : newY;
}
content.beginText();
content.moveTextPositionByAmount(x, newY);
content.drawString(row);
content.endText();
rowHeight = rowHeight + 10;
}
}
else{
newY = checkContentStream(newY, rowList.size(), space);
newY = newY == 700 ? 680 : newY;
for(String row : rowList){
content.beginText();
content.moveTextPositionByAmount(x, newY - rowHeight);
content.drawString(row);
content.endText();
rowHeight = rowHeight + 10;
}
newY -= (rowHeight - 9);
}
return newY;
}
This method which is in another class brings data from query:
private float renderSubscriptionNew(PdfRenderingPC pdf, float y, SubscriptionNew sNew) throws Exception {
DataResponse dr = dataSvc.buildResponse(folio, sNew, unitSvc);
List<Data> dataList = dr.getDataList();
int i = 0;
int j = 0;
float y2[] = new float[3];
for (Data data : dataList) {
String labelField = constants.getString(data.getName());
String value = getValue(data);
float xCoord = 0;
boolean getNewRow = false;
int fieldSize = 1;
switch (i) {
case 0:
case 4:
xCoord = LEFT_MARGIN;
break;
case 1:
case 5:
xCoord = MIDDLE_COL;
break;
case 2:
case 6:
xCoord = RIGHT_COL;
getNewRow = true;
break;
case 3:
xCoord = LEFT_MARGIN;
getNewRow = true;
break;
}
if (getNewRow) {
if(j == 0){
y = pdf.rText(xCoord, y, 10, labelField, value, fieldSize);
}
else{
y = pdf.rText(xCoord, y, 10, labelField, value, fieldSize);
float min = y;
for(int k = (j - 1); k >= 0; k--){
if(y2[k] < min){
min = y2[k];
}
}
y = min;
j = 0;
}
} else {
y2[j] = pdf.rText(xCoord, y, 10, labelField, value, fieldSize);
j++;
}
i++;
}
Any help, guide, would be pretty apreciated and thanks in advance
