# Known issues & Limitations: |
|
48
|
|
|
# ------------------------------- |
|
49
|
|
|
# Not so much an issue, the image is destroyed on the deconstruct rather than |
|
50
|
|
|
# when we have finished with it. The reason for this is that we don't know |
|
51
|
|
|
# when we're finished with it as you can both save the image and display |
|
52
|
|
|
# it directly to the screen (imagedestroy($this->imageResized)) |
|
53
|
|
|
# |
|
54
|
|
|
# Opening BMP files is slow. A test with 884 bmp files processed in a loop |
|
55
|
|
|
# takes forever - over 5 min. This test inlcuded opening the file, then |
|
56
|
|
|
# getting and displaying its width and height. |
|
57
|
|
|
# |
|
58
|
|
|
# $forceStretch: |
|
59
|
|
|
# ------------------------------- |
|
60
|
|
|
# On by default. |
|
61
|
|
|
# $forceStretch can be disabled by calling method setForceStretch with false |
|
62
|
|
|
# parameter. If disabled, if an images original size is smaller than the size |
|
63
|
|
|
# specified by the user, the original size will be used. This is useful when |
|
64
|
|
|
# dealing with small images. |
|
65
|
|
|
# |
|
66
|
|
|
# If enabled, images smaller than the size specified will be stretched to |
|
67
|
|
|
# that size. |
