Well, firstly, I am not expert at using Serif PagePlus: I have learned it as I have gone along in order to produce various results, such as a pdf, a png or a demonstration of my OpenType fonts performing.
So, I can say why I used a quickshape. As to the “instead of” part, it did not occur to me to do it that way and I did not realize that I could. I hope to try that method later now that you have mentioned it.
I used a quickshape as I am used to a text frame containing black text with a transparent background. So I simulated a piece of yellow paper to print it on.
Maybe there is a better way to achieve the result.
Well, I grouped the text frame and the quickshape prior to exporting the image as a png file.
Although the highlighted are for exporting the object was 512 pixels by 512 pixels, the dialogue panel offered 535 pixels wide by 512 pixels high.
Upon inspection in Paint, there was a white pale at the right side of the image, 23 pixels wide. So I adjusted the width within Paint to 512 pixels.
The overall effect was black lettering upon the yellow background.
So, as a check, I filled the background as red from somewhere near the middle of the surrounding area. This revealed a few lines of slightly different yellow near the edges. So I filled them red so that the whole of the area surrounding the lettering was red.
I then used the colour picker tool within Paint to pick the colour from the centre of the capital O and then I filled the area surrounding the lettering with that picked colour.
I then saved the image. That is the image in the first post in this forum thread.
I have thought of asking why the white pale is in the image in the Serif forum, though I am thinking of trying to produce a similar image using Arial rather than one of my own fonts, just in case the problem does not occur with Arial. The text in the text frame was justified with auto-hyphenation turned off. I did choose, and edit, the text so as to try to produce a good result.
As for using Paint, well, I learned Paint thoroughly during the late 1990s and find that it is good for images at a pixel level.
I do not know how I could have resolved the problem using only Serif software. Maybe it can be done, maybe very straightforwardly, it is just that I do not, at the present time, know whether it can be done and, if it can, exactly how one would do it.
I am interested in learning.
