The file A1-20140111.sla was made with Scribus 1.4 on a Mac. I compared the file on both Scribus 1.4.3 and 1.5.0svn on Linux. It is good in Scribus 1.4, but the "Associated Press Photos" line has too much space before it in Scribus 1.5. The extra space pushes the story headline into the story body. It looks like the difference is how Scribus 1.5 treats blank lines. In the story editor, the first two lines are 48pt, while the blank third line is 18pt. Scribus 1.4 handles that correctly, but Scribus 1.5 seems to reserve 48pt for the 18pt third line if the line is empty but 18pt if the line has text. In Scribus 1.5, PageItem_TextFrame::layout() in scribus/pageitem_textframe.cpp around line 2013, when it finds the empty line with only a paragraph mark, it increments current.yPos by style.lineSpacing(). This ends up as 41, which seems to come from the 48pt text on the previous line. I think that it should increment current.yPos by only font.ascent(style.charStyle().fontSize() / 10.0), which reflects the style of the paragraph separator. Frame and text sizes in points in the story 93.09 (1.4 needs 89.50, 1.5 needs 76.50) Headline WC 18: 48pt A coach Headline WC 18: 48pt of enthusiasm 49.19 (1.4 needs 36.50 points in this frame to make the text fit, while 1.5 needs 75.90 points, 75.90 - 36.50 = 39.40) Headline WC 18: 18pt (The empty line that causes the problem.)

An analysis of the sla shows that the emtpy lines which trigger the observed behavior have a fixed linespacing of 41pts which override the style linespacing. Given that fact, the 1.5.0svn rendering seems correct, and it seems the issue is in 1.4.x. >> when it finds the empty line with only a paragraph mark, it increments current.yPos by style.lineSpacing(). This is correct behavior. A line spacing based on the font size exclusively is incorrect. |

Thanks for looking at the file. When I compared the Scribus 1.4 and 1.5 code, I noticed that Scribus 1.5 has some additional tests for line spacing, and those tests might be the fixes for issues in Scribus 1.4 that you mentioned. Can you tell me where the fixed line spacing of 41 comes from? The style sets "Automatic Linespacing". The first two lines of text have a 48 point font, and the third (empty) line has an 18 point font. Also, if I place a lower case "x" on the third line, the line takes up less space with an "x" than when it is empty. I do not need this particular page to work, but before the new PDF printing options were back-ported from 1.5 to 1.4, a few people posted to the list that they had 1.4 documents that did not open correctly in 1.5. This might be a simple example of the problem. I would like to understand how the 41 is calculated and why adding a character to a blank line makes the line take up less space instead of more space. An explanation of the rules to calculate line spacing might also help people trying to move from 1.4 to 1.5. |

Thanks! I see those lines in the SLA. I should have looked there first. I found where to set the line spacing in the GUI. I attached a screen capture scribus14-linespacing-1sep14.gif from Fedora 20's Scribus 1.4.3. When I click on the blank line inside the frame, the Text section of the Properties window shows the 41pt line spacing, but the space is less than 18pt, so this looks like a problem in Scribus 1.4 that was fixed in 1.5. |

Closing as this is an issue in 14x that we won't reintroduce in 1.5.x. |
