Command line tool running under Mac OS X to generate the PDF or png.
PageComposer consumes custom file format *.pcd either from STDIN:
./PageComposer < stdin.pcd
or a file:
./PageComposer file.pcd
You can also provide output file name with -o option instead of the path in pcd like this:
./PageComposer -o output.pdf file.pcd
LineHeight設定了以後會讓英文字、中英混排時高度不同。所以設定單行文字要對齊底線時，建議不要設定 LineHeight 然後透過 BaselineOffset, BaselineOffsetCJK 對齊中英字形基線，然後再透過 TextVerticalAlign:bottom-baseline 來指定底線位置。（文字框高度要多留 bottom-baseline 的高度）- PageComposer 並不是 EXIF Orientation awared。也就是說他對於旋轉的資訊都是要透過外部程式判斷好 EXIF 方向再設定 ContentRotation。
The PCD format specify a graphic context whose coordinate system places the origin at bottom left.
You can use quotation mark (") to specify string containing space or tab. The following are legal string literals:
simplestring"string contains spaces""string contains escaped \"quotation\", tab(\t) and backslash(\\)"

simpleimage [url_to_image] [x] [y] [w] [h]
# The origin is at the left bottom.
# Draw the image and strech to fill the rect define by (x, y, w, h)
# image could be jpg/png/pdf.
## DPI limitation ##
set MaxDPI [dpi]
# Limit the max DPI. If the file is too large, it will scale down according to the MaxDPI specified.
# Only applied to jpg/png.
# Only affect the next draw image command.
## Content rotation ##
set ContentRotation [clockwise|counter-clockwise|half]
# Rotate the image first.
# Currently only support jpg/png.
## Rounded corner ##
set radius [r]
# Draw the next simpleimage with [r] point radius rounded corner.
# Only affect the next draw image command.
simpleimage image_a x_a y_a w_a h_a
simpleimage image_b x_b y_b w_b h_b
# Hence, image_a has r points radius rounded corner with MaxDPI limit.
# image_b doesn't have rounded corner and no DPI limit.
## Crop source image ##
image [url_to_image] [from_x] [from_y] [from_w] [from_h] [x] [y] [w] [h]
# Crop image from rect (from_x, from_y, from_w, from_h) and draw to (x, y, w, h)
# If from_x, from_y, from_w, from_h is of the form "[xX*][0-9\.]+", for example, x0.01, *0.5
# Then the actual cropping rect will be
# from_x * image_width, from_y * image_height, from_w * image_width, from_h * image_height
# Currently only support PNG and JPEG. PDF not yet support crop.
## JPEG compression ##
simpleimage_compress [url_to_image] [compress_ratio] [x] [y] [w] [h]
# Only allows JPEG image.
# The compress_ratio is between 0.0 ~ 1.0, where 0.0 results max compression, 1.0 results no compression.
image_compress [url_to_image] [compress_ratio] [from_x] [from_y] [from_w] [from_h] [x] [y] [w] [h]
# Crop image from rect (from_x, from_y, from_w, from_h) and draw to (x, y, w, h)
