Graphic scaling question
Posted by: antone <antone@...>
printing. Setting up the field is easy. What I'm having trouble with is
determining the size of the original picture so that I can calculate the
picture field rectangle. The original picture is created in the program
with picture on/picture off statements. When I try to get the pictures
rectangle using the method of the example in the handbook:
DIM rect.8
rect;8 = (myPict&)+_picFrame
I get numbers out like:
rect.top% = 14080
rect.bottom% = -30768
rect.left% = 202
rect.right% = 206
Also, if I run the program several times (and create the same picture
everytime), the numbers change every time the program runs. This leads
me to believe that the numbers have nothing to do with the picture
itself. Can someone tell me what I'm missing? Are the dimensions of a
picture contained in the file, and can they be accessed easily?
The final goal of this project is to check if the size of the original
picture is larger than the printable area of the paper. If not, I want
to print the original picture, original size. It so, I want to scale it
proportionally so as not to distort the picture, but it should fit in the
printable area. Am I on the right track, or is there a better way to
approach this?
